We’ve had news of the new Sigma Art HSM high speed wide angle full frame zoom – 24-35mm f/2.
It will be available in Nikon, Canon and Sigma mounts only (release date not yet confirmed) according to Sigma in the UK.
Note that this will be a bit of monster with its 82mm filter thread, 117mm long barrel and substantial petal lens hood.
Sigma does not make a full frame DSLR. Sony is now a major market for high end full frame lenses. What’s going on here? We’ll just have to wait and see. Maybe Sigma just reckon every FF Sony mirrorless owner will have a Canon AF adaptor and maybe their HSM – which works pretty well on the A7II – will even allow fast AF on the new A7R II.
Well, I never really liked what Hasselblad did with the smaller Sony cameras – but what they did with the A99 is pretty cool, with the different body skin and control details. At the original price? A rip-off!
For $3999 including a 24-70m CZ lens and a special case – a bargain. This is still an amazing camera. OK, at the official price of $11,999 it would have been the badge of a wealthy eejit. At $3999 it’s a snap-up deal for anyone wanting the highly capable A99 in a form which will have wedding guests keeping their mouths shut even if they do have a cheap old Canon 5D MkIII round their neck.
B&H have this offer right now.
And for purists, they have an equally extreme reduction on the Sony NEX-7. Make no mistake, this is still a top end classic with excellent controls and it works with the older Sony hot shoe. It is only $498 with the 18-55mm lens, all in black. That’s amazing.
B&H NEX-7 with 18-55mm – reduced from $1248 to $498.
(Updated June 15th after press conference)
The new Sony A7R II is the camera I’ve been waiting for, which everyone has predicted, and which seems to tick every box without having a huge price label on its own. I find the $3,200 (UK coinfirmed £2,600) matches its stated specifications well. Others may disagree, but they’re probably influenced by the price collapse of the original A7R, now occasionally found for under £1k.
Even so, at $3,200 the A7R II commands a $1,500 premium over the A7 II and much of that must be what you pay the new sensor – which does not seem to be licensed or sold to any other brand. Not even to Nikon, yet. The A7S remains the most expensive model despite the minimal 12 megapixel capture and lack of in-body stabilisation (SS in Sony terms, or IBIS generically).
On Monday June 15th I flew to London to have a look at the A7R II and the new RX10 II (£1,200) and RX100 IV (£850). This was a bit like a motoring journalist going to a car launch and being told, you can sit in the seat, waggle the gearstick but don’t start the engine as no photography was allowed with any of the demonstraton cameras. I was surprised to find it was a European conference, as this normally means journalists from across the Channel have a facility trip to be present, and that seems very extravagant just to look at cameras which can not be tried out. I wish I lived in France not Scotland – it might not have cost me almost £300 to be there, eight miles from Heathrow (but an eight miles which might as well be a fifty Scots miles!).
Don’t expect to get one on June 17th, as B&H’s information and too many bloggers have repeated. We are told by B&H it won’t arrive until August even though pre-orders open on June 17th in the USA. It may be later arriving in some regions. Demand is going to be so high that if you want one, you’ll need to crash into that queue…
But you can snag a Canon EOS 5DS – 50 megapixels – for only $3,699 right now
A7R II – or A7 II R?
In brief, the A7R II consists of an A7 II body with a new 42.4 megapixel backside-illuminated CMOS sensor, same Bionz X processor allowing 5fps at full resolution, new 399-point Phase Detection AF on the sensor covering most of the field (up from 117 points), a similar EVF with improved eyepiece giving a genuinely impressive 0.78X instead of 0.71X virtual magnification, the same rearRGBW bright LCD, plus silent shutter and HD 4K movie functions improving on the offering of the A7S. The new shutter mechanism is claimed to have a 500,000 actuation life expectancy which puts it ahead of almost every pro DSLR yet made. The back of the camera body is magnesium, where it’s solid composite plastic in the A7II. And it has, unlike the A7R, five-axis sensor stabilisation which talks to Sony OSS lenses for the best blend of anti-shake methods ever devised.
The new EVF size, to the eye – compared with the old (A7II, A7R, A7) 0.71X view below (A7R, Sigma 12-24mm at 12mm, Canon EF fit, on Commlite EF-FE adaptor).
You will read in the specifications and promo blurb that it has a new LCD double the brightness, new tough body and strengthened mount, new shutter release and controls but all these ‘improvements’ are listed by Sony over the A7R and already existed in the A7 II. Instead of making comparisons with the A7 II – which this is really a development from – Sony has listed many advances made relative to the A7R. It is not an A7R II. It’s really an A7 II R.
The eyepiece surround is much improved, wider and softer still than the A7II which in turn is softer on specs then the earlier models. Eyepoint and position flexibility both improve and there are no unsharp zones at all even if you shift your eye around.
It’s important to understand that many of the improvements already exist in the A7 II partly as a result of criticisms of the original A7R made by objective reviewers, not Sony artisans or staff or sponsored bloggers. You don’t owe this camera to the success of its predecessors or the daily Facebook sermons of awestruck evangelists – you owe its features to corrections made to the shortcomings of the models so far. And to those who have had no vested interest (other than ownership) persuading them to weaken critical appraisal. The further improvements in the A7R II are either extremely technical – serious core improvements in the sensor and focusing – or minor refinements and carries-over from the A7II.
42.4 versus 36 point anything
If you really think 42.4 megapixels is going to take you to realms far beyond your 36 megapixel sensor, think again. It is the same step up as from 18 megapixels to 21 megapixels, a move Canon made without absolutely transforming the images created, or about the same as from 10mp to 12mp. There’s one big difference – it does not make the jump to any larger common print or repro size. Remember going from 6 to 8? That was from sub-full-page to a decent full page resolution, for US or A-size documents at a touch under 300dpi. 24 megapixels took us to a really sharp A2, 36 megapixels takes us to a acceptable A1, and all that 42 does is to make a slightly better A1 but not 300dpi.
Above you can see the actual, real size difference (in proportion) between a 36 megapixel shot and a 42 megapixel shot. If you click on the bigger version, it will take you to my pBase page with a full A7R II sized version of this A7R shot. Zeiss? No – a 45 year old Asahi Pentax Super-Multi-Coated Macro Takumar 50mm f/4, used at f/11, and a 30 second exposure at ISO 50 lit using the ICE Light 2 moved round the subject in horseshoe shaped path for 15 seconds, laid flat, and then moved under the perspex for the remaining 15.
In practical terms, it’s 7980 x 5320 pixels (or very close – Sony has been extremely coy about releasing full specifications, even at the conference I could not find this out) versus 7360 x 4912 for the A7R. In perspective, make a big print from the A7R and it’s 24.5 inches long at optimum resolution; use the A7R II and you get one inch extra each end on the long side, 2/3rds of a inch extra top and bottom. The A7R makes a 16.3 x 24.5 inch print to perfection; the A7R II makes a 17.7 x 26.6 inch print.
Anything smaller than A4 printed, it’s got no great advantage over the 12 megapixel A7S – but you are getting close to enabling a 2X crop (one quarter of the frame) to look as good as the A7S full frame. Sony showed A3 prints. They could, honestly, all have been shot on the Sony A100 from 2006 and no-one would have been any the wiser. One enlarged section was the only real test of the camera. I’m sure the model’s dermatologist loves it.
Where it does count most is when using crop frame mode. In APS-C crop mode, the A7R II file is large enough for a 300dpi double page fine art magazine spread, just under 18 megapixels. I’d say that where 42.4mp is not a critical size, 18mp actually is. You can get away with 16, and for Nikon, Panasonic, and Olympus this had been an important baseline. Cropped frame FF from Sony now rises above that baseline instead of sitting just below it.
What I’d like to see would be 1:1, 4:3, 5:4 ratios implemented with the EVF and LCD screens cropped to match – and ideally the raw files reduced in size the same way. A square 1:1 would be 28 megapixels and that crop allows so many APS-C lenses (like the Zeiss Touit 12mm) to be used without vignetting or limits of coverage distortion issues. The example above is from the A7R and it’s a square crop 24 x 24mm from a frame taken with the 10-18mm f/4 Sony OSS, at 11mm; the lens would have allowed a 4:5 crop equally well.
Important edit: just read another ‘Sony artisan’ blog post asking the (redundant) question as to whether Sony lenses will be up to this new resolution. Anyone who owns an A6000, NEX-7, or A77 is already shooting at well above this resolution (full frame will need to match the Canon 5DS 50 megapixels to beat them). The resolution of the A7R II is slightly lower than that of the base level entry A3000. Don’t panic. Plenty of old legacy lenses will match it well, let alone any new Sony FE and A-mount designs.
I checked out the 20mm f/2.8 SEL lens with the new version 2 wide and fisheye black converters on full frame at the Sony event. Really, this lens comes so close to doing a good full frame and the converters even leave much of the area intact for a much bigger crop than APS-C.
And that’s all without removing rear baffles or doctoring the built-in lens hoods of the converters!
When we get a chance to use the camera, the following points will be of interest:
Has the mount been upgraded again? It still has only four attachment screws, compared to Fujfilm X system’s six screws (and the A-mount uses six too). My two camera bodies and two changes of mount on the A7R, to Tough E mount and then 2nd generation Tough E mount, all produce unpredictable degrees of slop, smoothness or jam-on tightness from various adaptors showing that no matter what, tolerances are broad. Comment: can’t tell from changing lenses at the event, it feels much the same as the A7 II.
Has the Memory position, 1 and 2 on the mode dial, been improved to remember MORE of the important settings – notable, Setting Effect ON and OFF, for saving a studio flash preset mode with the EVF/LCD setting effect disabled? Answer: No.
Is the hot shoe part of the Multi Function Accessory Shoe hampered by paint, or tolerances in fit, or does it readily accept all standard ISO hot shoe simple flash devices and triggers? Looks clear.
Canon 85mm f/1.8 USM on Focus EF-FE adaptor (also works perfectly with Commlite) on A7R. The 40mm f/2.8, and Sigma 12-24mm in EF mount work well on my A7R with these two sub-Metabones price adaptors. At the press event we found the 85mm just didn’t focus at all with any adaptor on any of the pre-production A7R II bodies, but the 40mm was fine.
Will the promised ability to use PD-on-sensor AF with Canon and other lenses rely on Metabones as the only adaptor, or is it generic? The microlenses on a backside illuminated sensor have a large effective aperture than traditional design, and this means the PD-lenses (a special variant of the microlenses used on sensel pairs) will be similarly improved. This may make some difference, but it’s actually the focus motor control via lens to body data communication which will enable fast and sure operation with Sony SSM on LA-EA3, Canon USM on EF-adaptor, and so on. Remember, this does not make screw drive or SAM, or micromotor Canon AF pre-USM lenses, function any better. It will only apply to ultrasonic, piezo, linear motor and similar finely controllable AF mechanisms with close to zero play and accurate (8 contacts, not 5) distance and ‘state’ reporting. Note, too, that Sony’s revised lenses (SSM II) are not just optical and weatherproofing reworks – the new SSM is designed to work with contrast detection, as found on the A7R, much better.
Comment: we found that the Canon 85mm f/1.8 USMdidn’t work on any adaptor on the A7R II, while the 40mm f/2.8 activated the PDAF points and focused very rapidly, and a 24mm f/2.8 USMf/2.8 focused fast – and that various different demo A7R II bodies responded differently and one malfunctioned a lot of the time even with Metabones. Sony said this was known and the final retail stock should at least work OK with Metabones IV and probable firmware updates, but other cheaper adaptors will not be tested.
The new camera’s mode dial has a central lock button, and a slightly lighter click action without risk of being turned by mistake. We’d had liked to have seen a lock on the +/- EV compensation dial too, but this just has slightly strengthened clicks.
The same small battery has been used yet again despite the II body design having what looks like enough room for a full sized Alpha battery (see below – carefully positioned batteries with A7 II body). Let’s hope for upgraded batteries from Sony.
Please, Sony, you provided a GPS pinout in the new shoe – you have never rolled out a GPS module or firmware. It’s three years now and no news. Hell, I nearly bought a brand new boxed A99 at Dixons Heathrow Terminal 2 shop for £1075 inc VAT maanger’s special, I miss GPS so much!
Please let the Lens Data entered into the menu for SS of manual lenses, without data communication, be embedded into EXIF so if I enter 50mm, my files say so. And ideally, please make it possible to enter the focused distance (this would improve stabilisation) and the aperture in use (just to complete the EXIF data).
Sony pointed out that the latest version of the lens correction App will record the focal length and aperture as you enter them, in EXIF. It has its own SS on/off setting and automatically recognises whatever focal length you have entered. You can name and recall each different lens, and if for example you normally use your 24mm f/3.5 Samyang shift lens at f/16 for architecture, you can enter f/16 as the lens’s aperture and that will be corrected embedded in your EXIF. But to get this you must run the app, not just shoot with a manually set focal length for SS.
Please change the Memory 1 and 2 registers to save and recall ALL the camera settings and not just those in the first bank of the menu system (but see the vital point above about Setting Effect On/Off). Until I test the camera, no more to say – but Sony does not usually keep quiet about changes, and has not mentioned this aspect.
The existing rear screen – the II design, left, improves on the original A7R but this is still a basic, amateur level screen to be working with and a fully articulated design would be better.
Though you’ve missed the boat with this camera, the crudely hinged and angled rear screen needs to be replaced with a fully articulated screen that can be reversed to the camera for protection and to prevent distracting light when working in the dark.
Out of the loop
I’ve been out of reviewing new Sony gear for some time, as it has not proved possible to get hold of it early enough or for long enough to give any meaningful assessment which Joe Photographer anywhere in the world couldn’t appear to do themselves. For six or seven years I have bought and sold new Alpha gear to fill the gaps between the occasional availability of review kit, but recently that has become so expensive it exceeds any margins available from the three magazines I publish, or any fees I can obtain from other media. Like politicians, people who write about gear either need an independent mind or independent means – without one of these, you’re always in someone’s corporate pocket or feeding from crumbs under the main table.
The result, as we see all the time, is that many early users or reviewers of Sony kit are no longer all that independent and much of the first wave of information now comes through the channel of ‘artisans’ (as it does with ‘ambassadors’ for all makes). And we see plenty of others who are clearly of independent means, whose main purpose in life is to be the first to post pictures taken with new item X regardless of the cost.
So maybe I don’t need to push to get hold of an A7R II for the too-short two week period of any review loan, after a six month wait while other consumer-orientated magazines and blogs take priority – or indeed rush to buy one.
But… like the RX10 which I use all the time… like the A6000 kit which is co affordable and compact it’s essential… like the RX100 MkIII which goes where even the RX10 is not welcome… like my A7 II with stabilisation which has transformed a box of assorted lenses into a solid outfit… this one’s possibly something to buy because I actually need it and will use it.
I may not even cosy anything as it will make both the A7R and A7II redundant, because it does both jobs and also covers the A7S I did manage to borrow but never bought. And it does more.
So, thinking whether or not to bother with this upgrade is a bit irrelevant. Even if it was still ‘just’ 36mp the other improvements would mean it still replaced the need for a handful of A7 models, all in one.
My one doubt is that the A7R II may be beaten in practical terms by the RX10 II. Please note that so many incorrect snippets of info have gone around about the ‘stacked’ sensor design, I thought it referred to RGB stacking. It does not, the sensor is a conventional Bayer pattern, and what is stacked is the electronic substructure. This does not affect the top side of the sensor and the performance in image quality should be similar to the existing models. What it does is greatly speed data transfer and enables over 1000 (lower resolution) frames per second to be clocked through from photon received to movie frame recorded.
The RX10 and 100 new versions offer ridiculous levels of high speed slow motion capture, clean 4K video and other technical benefits which come with a very small chance of dust on sensor, unlike the A7R II which is almost guaranteed to be a dust devil. Why do I say that? Because a backside illuminated sensor renders dust on its cover glass even more sharply than a conventional one! We know the RX models are not dustproof and if you are unlucky enough to get a spot on the sensor it’s a service visit to get it removed, but in my experience with five or them so far I have never had a single dust spot.
So what? Just retouch? Not when making movies! Admittedly most movie makers will open up the lenses to max or only a stop down on these 1″ sensor cameras, and would open up lenses just the same on the A7R II and never see dust even if it was there. But what about the time you want that ‘American take’ – f/22 at 20mm? Traditionally they were taken in dusty settings for the spaghetti westerns!
All I can say is that the RX10 has come very close indeed to removing the need for any other camera and it’s been a pleasure to work with the raw files. The RX10 MkII might be so much better that I forget about DSLRs or mirrorless systems and just get on with capturing great images. Or then again…

Twenty years ago I was operating one of the first full service digital photo studios in the world. I had already published, back in 1986, the world’s first desktop published commercial periodicals and won the UK Printing Industries Research Association inaugural DTP Awards, in 1987, for this. We’d bought the first Apple laser printer in provincial Britain and when Letraset’s ReadySetGo layout package failed to produce usable output for our first such magazine, Aldus stepped in and provide a pre-release beta of PageMaker. In 48 hours, I had to re-create the entire magazine – and it worked.
From then on we progressed, through having the first separation-capable film imagesetting in Scotland to reproducing the first magazine cover from Kodak Photo-CD and soon after the first full colour page from a Kodak DCS camera. By the beginning of 1995 we had Photon, the first major photo-mag style website, in by the end of that year we had a Leaf Lumina based studio with Scandles lighting. There’s an article about this in our repository of occasional articles, dphotoexpert – http://www.dphotoexpert.com/2007/08/06/the-leaf-lumina-scanning-camera-1995/
That year, Shirley had planted an entire bed of flowers specifically for drying. They make good photographic subjects. The (now relocated) university college of St Margaret’s in Edinburgh asked me to give a lecture about the new technology – and so the Leaf Lumina (a scanner on a tripod with a Micro Nikkor up front, and an Apple Mac Powerbook on the end of a SCSI-2 cable) went along with the fluorescent studio light heads and a tray of the dried flowers. We also took our Kodak dye-sub printer, which had made hundreds of prints alongside other printers during that year, when Shirley completed her M.Sc.Colour Science and created pre-ICC colour tables to reproduce fabric colours accurately. With this carload of gear, we were able to shoot and produce a print on the spot.
The picture remained on file – a 25MB TIFF, roughly 8 megapixels, but equal to 8 megapixels in the Sigma Foveon sense as every pixel was true RGB with no Bayer filter involved. The exposures took over a minute, limiting it to still life, but the quality was not exceeded until 12 megapixel Bayer cameras like the Sony A700 appeared. And a few months later, we were producing Paterson’s catalogues and price lists and needed a cover. One list covered black and white and colour chemicals, the former mostly from Paterson and the latter from Photo Technology. Photoshop offered an easy way to take the image, and divide it accordingly. So that’s what we proposed, and what was used for the cover.
It was intended to show the gamut from plain monochrome through toning to colour and it did look very good in print, because relatively low overall contrast combined with high detail contrast is easily handled by litho.
Now, forward two decades, and I’m looking for subjects to test out the latest Elinchrom ELB400 portable li-ion powered two head flash kit. This has LED modelling lights over twice as bright as its predecessor and they now really show how the light is falling even when using light shapers. I wanted to show texture using my optical Mini Spot attachment, which works very well with these new heads and their cool-running LEDs.
On top of a wardrobe, in a basket, were the dried flowers. They are called everlasting and apart from gathering loads of dust, they are. The most difficult job was holding each flower against the nozzle of a handheld vacuum cleaner to remove 19 years of dust.
The first shot I took was with the Sony A7II, 24 megapixels, using my Pentax SMC Macro Takumar 50mm f/4. Like the flowers, this is also everlasting. It’s not yet 50 years old even though the lens design, a simple Tessar-type corrected for magnifications from 1:2 (50%) to 1:10, is well over 100 years old. It’s also a tolerable lens for general scenes, though the extreme resolution it achieves centrally only covers the full frame when you focus close. With Pentax’s original multicoating in every way a match for the latest Zeiss T* as found on new Sony Zeiss lenses, and a deeply recessed very small optical unit, it has a contrast and colour saturation you just don’t find from lenses using hybrid or moulded aspherics or many more air to glass surfaces.
This picture appears, fairly small, in my review of the ELB40 in f2 Freelance Photographer magazine July/August 2015. When editing it, I was struck by the extreme resolution. Within the planes of sharp focus, it was exceptional.
So, I decided I’d shoot a new shot, and improve on the use of the spotlight attachment on the Quadra head to cast the shadows and create a sunlight-like effect – and this time, use the A7R with its 36 megapixel resolution. Although the A7R has no AA filter and is sharper in theory, the larger pixel count calls for a smaller aperture to secure a little more depth of field for the larger viewing scale, and this when using any macro lens always risks diffraction limits on fine detail contrast. For example, at half life size a setting of f/12.5 (between f/11 and f/16) which I found desirable for best sharpness distribution gives an actual f-stop of c.f/19 and this does cause some sharpness loss. If the lens was extended on a tube to give 1:1, a setting of f/16 as nearly always needed for depth of field is really a true f/32 for diffraction calculations and light readings alike.
Fortunately, our brains are sensitive to perceived scale, and we ‘see’ close ups as sharper than distant subjects even when they are not. The A7R and the Pentax macro lens also combine to produce an extreme level of textural detail, the information our eyes and brains use to see 3D solidness, shape and form in a flat photograph. So in practice you can shoot macro and use whatever aperture the subject depth demands, without resorting to focus stacking techniques.
And here, anyway, is the result. You can click on this image and it will take you to a pBase hosted full size, JPEG compression level 12 version (this is over 24MB of image data, and it is not compressed like Facebook or indeed a WordPress image – though it’s still not ‘virgin’ data).
In a couple of days, I have another SMC Takumar of the same era arriving. It’s a 35mm f/3.5, which was the cheapest of the line back in 1970 when Shirley bought me my very first brand new, marque brand lens for Christmas! We were both only 18 and that represented an entire month of her basic salary working behind the counter at Dixons in Sheffield… helped by a staff discount. It was my first Super-Multi-Coated lens and I can remember still how the high contrast and bright colours could even be seen through the viewfinder – and how amazing the first box of slides looked, midwinter close-ups of fallen leaves rimmed by frost and frozen puddles.
These lenses have never lost the edge they had, if they have been looked after, but the truth is we never knew how good they really were. We can now focus them within a fraction of a millimetre. I’ll probably never compare the 50mm f/4 SMC Macro Takumar with the 55mm f/1.8 CZ (I’ve used it, but only for low light high ISO tests on the A7S) or the 35mm f/3.5 with the CZ 35mm f/2.8 because it’s unlikely I’ll ever buy the new lenses with their inflated prices and reliance, however marginal, on software correction to be ‘good’.
I know I have not written much about the A7R, or the A7II I’m using, or about any of the new lenses I can not manage to borrow from Sony and can’t afford to buy. I have an amazing set of lenses from 12mm to 500mm for full frame, including tilt-shift, wide aperture and mirror but just one single Sony FE lens for convenience (the 28-70mm FE kit lens). In contrast, my A6000 kit is all Sony plus the Samyang 12mm f/2 because it is just so good it had to have a place.
So, please do take a look at the full size file. The critical plane for focus crosses the smooth surfaces of the two poppy seed heads and it’s in this relatively low contrast zone that the quality of the lens shows up. Elsewhere in the image the defocused quality is very pleasant (there was no CA to correct and there’s no bad colour bokeh) and the plane of sharpness passes through a few other more interesting flower details.
Finally, a word for A7II users. If you use a manual macro lens, as I do, remember that when you program in the focal length for Steady Shot you should only enter the actual focal length for distant views. For my 1:2 macro Pentax, most often used in the range from quarter to half life size, I program in 70mm as the focal length because this represents the view angle. Using a macro at 1:1, you should enter double the focal length to get the correct Steady Shot compensation. Sony and Minolta macro lenses with the D chip (eight contacts) convey accurate extension information, so the auto Steady Shot works perfectly with them. But manual, or Canon lenses on adaptors which may or may or not pass the right information through, are best used with the Steady Shot focal length entered via the menu screen and adjusted to allow for the actual lens extension.

Sometimes you find a chunk of glass which just works. One of the problems with lenses is that you can never have too many. They overlap, they duplicate each other, and yet they can be so different that you need every single one. The new Samyang 12mm f/2 for mirrorless APS-C systems is one of these. It’s the budget alternative the Carl Zeiss Touit Distagon 12mm f/2.8 T*, and so far everyone I’ve found who has used both lenses – including me – rates it as better optically. This isn’t what you expect from a lens with twice the maximum aperture at half the price.
I have good reasons for not owning a Touit 12mm. I already have a Sony 10-18mm f/4 OSS E, and rather like the Fujinon XR OIS 10-24mm f/4 this lens offers nearly perfect performance as a working ultra-wide zoom and adds the benefit of stabilisation for video or tripod-free interior shots.
The Sony appears to have very fine detail sharpness wide open, little sign of fall off in illumination or sharpness, and good geometry.

However, the Samyang when used on the same Sony NEX-6 16 megapixel camera forced a reappraisal. It offers sharpness on a different level and manages to do so even at f/2, with corners far more detailed and clean than any lens with a 99° angle of view should manage.
It is equivalent to an 18mm on full frame, and this is around my favourite angle for an architectural, street and general lens. Where the 24mm angle is a common feature of consumer zooms and easy enough to use, lenses in the 17-21mm equivalent range produce a distinctive result but need careful composition and an understanding of perspective and lens geometric projection. Lenses like this separate the experienced user from the unskilled masses.
Stopping down to f/16 secures great depth of field (the Canarian cacti are not huge, bush sized and very close not tree size!) with just a hint of sharpness loss. Click image for a full 16 megapixel file
Weighing only 245g, it’s not a big lens though it has a generous 67mm filter thread round a much smaller front element which does not protrude. The bayonet lens hood is removable and reversible for storage, with a soft pouch supplied to hold everything. You can use circular filters without cut-off provided they are reasonably slim-line, and filter systems from 75mm rectangular upwards. Our sample was in a matt silver finish, with conventional black as an alternative. The focusing down to 20cm is very smooth, with a travel of 135°, and the aperture is click stopped gently but positively in half steps all the way to f/22. The mount is metal, as is the barrel skin, though plastic components are used internally. It is an advanced design with 14 elements in 10 groups using both low dispersion and compound aspheric glass, nano-coated with Samyang’s water and dirt resistant hard NCS multiple layers.

Though this lens had to be manually focused and lacks any electronic connections, it rapidly proved to be a reliable companion. Auto exposure tended to be slightly under, and auto white balance was nearly always too cold. On the NEX-6 manual exposure and a fixed daylight or custom set white balance proved better than relying on auto setting.
The results are the reward. For its aperture and angle, it defies the laws of trade-off. The geometry, even without creating a profile or applying the slight barrel correction sometimes needed, is so good that uncorrected raw conversions worked perfectly. The example above is a full frame, with no correction at all (you can click the image to open the full size file, though remember it has strong compression for storage and display here).
Here is the same view taken with the Sony 10-18mm, at 12mm, and at f/11, exactly the same compression
For some subjects, a two-pixel blue chromatic aberration correction removed a barely visible tendency to purple fringes, more likely to affect high contrast patterns than high contrast edges. The lens has such high resolution that moiré patterns appear from many subjects.
Compared to the Sony 16mm f/2.8 fitted with a 12mm ultra-wide converter – the original Sony solution from 2010 – it’s like moving from small to medium format.
Here’s an example which shows the geometry of the lens pretty well (click for full size)
And here’s the same historic suspensioon bridge, again at f/11 to get the necessary depth of field. But the sharpness is not destroyed and a 100% clip shows the spiders have been busy (compression almost loses the strands of the webs which are easily seen in the original file):
It does not have enough circle of coverage in reserve to make it valuable on full frame, but a near-24mm square can be cropped on the A7 series.
This lens would be a dream to use if it incorporated a chip to convey EXIF data including the aperture. AF really doesn’t matter, after a few days I learned to preset the focus manually and only check the most critical wide-open subjects using magnified manual focus view. At under £300, it’s so tempting just to have it for the sheer sharpness right into the extreme corners and the straight-line rendering. Much though I like my £700 10-18mm it has had less use since the Samyang arrived – and that says it all. My main reason for sticking with the 10-18mm is its ability to work well on the A7R for 15mm shots, and its full recording of EXIF data along with full control from the body. Much though I like my boxful of manual lenses, after a year and more using them, I am missing the vital data – as going back a year to look at original files shows. Unless I made a special note at the time, I often have no idea what lens was used let alone what aperture. For these shots, of course, I noted the details.

Just got this link from B&H, ideal for our US readers – http://www.bhphotovideo.com/c/product/817858-REG/Sony_SLT_A77V_SLT_A77_Digital_Camera_Body.html
It’s for the original A77, body only, at $549.
This is a ridiculously low price for a body with GPS which, bar a small improvement in high ISO performance stated to be 20% (I think it’s a bit more) is not far from the A77 MkII and if you have older flashguns or triggers like the Pixel King set I’ve bought recently remains ideal for flash work.
That is a single shot at ISO 100 using an iLux Summit 600C flash head set on 10fps strobe, with the 16-80mm CZ lens at f/20 (it’s a powerful flash) and wireless triggering. Owl in our studio, working in complete darkness. The A77 didn’t suddenly stop being a great camera because the A77 MkII arrived! At $549 with (apparently) $77.38 of free accessories this ‘holiday special’ looks like a steal.

Machined from brass and chrome-plated, in the tradition of lens mounts from 50 years ago and not necessarily the best solution for precision or lifetime wear, Fotodiox’s TOUGH E-mount is a replacement body mount bayonet which you can fit to your existing A7R, A7, NEX-7, A6000 or any other metal-mount E-mount body in a few minutes. You need a clean well lit work table, a small engineer’s or large jeweller’s crosshead screwdriver, and a similar flathead screwdriver or old credit card.
The NEX/A bodies are fitted with a three-part lens mount. Here’s what a bonded, single piece, original Alpha lens mount looks like when removed from an old Minolta 7000 –
This mount is stainless steel, which would be prohibitively expensive for a small shop engineering replacement on the E-mount. It’s in two parts, a front surface and the inside with a bonded bayonet spring pressure action, a thin shim with bent ‘arms’ forming three pressure points to hold the lens tight to the mount.
From Fotodiox comes this neat box taking 10 days to the UK from USA –
Since I also ordered a focusing Leica M to E adaptor, my overall value was marked as $80 and I had an £8 admin charge and a little over £7 in VAT to pay.
Inside, the TOUGH E-Mount is boxed and bagged without instructions. For these, you visit the Fotodiox site and watch a video:
Here’s the rear face of the Fotodiox mount, which does not have any second layer of spring metal to grip the lens:
However, as we will see, this component (fixed to the mount for the A-mount design) is a separate loose item which sits in the camera body mount recess on the E-mount, and performs exactly the same function. You could probably remove it and bond it to the new mount.
So, why replace the E-mount on a £1200+ camera body like the A7R, which has a magnesium body casting into which the lens mount is anchored by four screws? The reason given by Fotodiox is that an intermediate plastic moulding is used behind a simple unprofiled mount face, so two parts make up the overall thickness. The tensioning ring sits behind the plastic ring, forming a three-part sandwich to make up the mount. The front mount is a relatively soft, crudely CNC lathed alloy.
Here’s my camera after 10 months of use. This camera has shown signs of light leaks, and has not been sent back for a fix. The mount flange is a completely flat item, relatively thin, and the leaks may be partly down to slight distortion of the front plane face, as shown by uneven wear from lens mounting.
Here’s a detail. You can see the lathe circles on the mount face, and you can see where the metal has abraded and either collected plastic from a plastic lens mount (most likely my MEIKE extension tubes) or paint from a cheap adaptor (my Novoflex and Fotodiox adaptors don’t use paint, they are anodised).
The mount is very simple indeed. It can be removed from all the cameras without disturbing the electronic contacts or the lens release mechanism.
Fotodiox video shows the camera on its back and warns about dropped screws etc. I just prefer to unscrew each screw in turn with the camera held vertically on my table, so that if the screw drops it won’t go inside the camera. Care is taken not to allow the spring loaded lens changing pin to disassemble itself, but that’s really very easy.
One removed, you can compare the Sony ‘washer’ (which is really more or less is!) with the Fotodiox mount – a much thicker unit, stepped to fit the recess on the camera body. A point worth noting is that the original mount has no recesses at all to fit over the four threaded posts on the camera body. Its position is maintained by two pins (at 9 and 3 o’clock) which engage in two holes on the otherwise plain flat rear face of the mount. The Fotodiox mount not only engages with these pins, as it replaces the plastic secondary mount shown below, but also has holes into which the threaded posts fit. It is better proofed against rotation.
You now see the plastic middle part of the sandwich. This is secured by a very thin double-sided tape in places. A flat blade screwdriver or a suitable cut piece of old credit card (or indeed a guitar pick!) pushed gently under the plastic at various point all round will free it. It lifts out easily. Unless you are amazingly clumsy you are not going to go anywhere near the sensor but if you have a clean 40.5mm filter or lens cap around, you can pop it in to cover the sensor safely. I used a 62mm filter to place over the whole mount when checking instructions and looking at the parts, as I don’t want to risk hairs and dust covering the upturned unit.
Underneath the plastic component you’ll find the third part of the mount, the thin flexible stainless steel tensioning ring which acts to pull the lens tight against the front face of the mount. You may note that if your lenses ever begin to seem slack, it would be easy to re-tension this ring by a gentle bend to the three arms. The four screw holes are in metal posts mounted directly into the magnesium body. The plastic ring can be argued to have no effect on precision, as the original mount rests on these posts, leaving the plastic and the stainless tension ring more as a ‘lubricated’ assembly with a little ‘give’, affecting only the tightness of the lens to the body. The plastic has no sacrificial role, as it does in many lenses (Sigma, Tamron, Nikon, and Canon all use plastic to create weak points where the lens will break on hard impact rather than having it shear the body mount off the camera – not sure about Sony).
The final step is to place the new mount, aligned with its white dot and cut-outs and screw holes, in the only position it will fit. Please note that the TOUGH wording goes inside and is not shown on the camera front! Again, I don’t place the camera on its back, and prefer the control given by holding both the camera and the screwdriver (which if properly chosen will support the screw). No pressure is needed to locate the screws for a few turns. I rotated the camera so that the screw hole being worked on was always below the sensor. Finally, when tightening up each screw in turn to a firm fit, the camera was laid on its back and my 62mm filter was placed to cover the mount opening, held firmly. You can also just place a finger against the screwdriver on the ‘inside’ while tightening up, so that if for any reason it slips, you block it from entering camera.
Once fitted, there’s little more to say. It looks a touch classier than the cheaply machined soft metal Sony original, it is a snug and perfect fit, and lens mounting has a slightly more solid feel without resistance or any scraping sensation. Fotodiox may be taking the mickey by suggeting you give the old mount to the cat to play with, of course you should keep it carefully. While doing this I discovered that the original old Minolta SR bayonet shares the screwhole locations and almost perfectly matches the overall size of the E-mount. I could actually take a Minolta SR bayonet off the front of some old extension tubes and fit an E-mount in place. This would serve no purpose but it’s a fascinating hint at the pedigree of the new system – it has a three-flange bayonet so similar to the SR mount, introduced 52 years after Minolta’s SLR debut!
Everything worked perfectly as expected once fitted (see notes below). Cost – $39.95 plus shipping. I consider it a good upgrade.
Notes on infinity focus, fit, and light leak issues
While Sony native E mount lenses seem fine, some of my third party adaptors are not fitting well, and very short focal length lenses show that the infinity focus may be affected. If you use lenses 12mm to 20mm on adaptors, proceed with caution. I am not able to get the Kipon tilt shift adaptor to mount without a forceful twist, though a similar age Kipon shift-only adaptor is happy enough (just no longer able to hit infinity with my chosen 20mm lens).
Infinity collimation after tests and measurements – I’ve now checked infinity focus using stars. I’m just OK on all but one lens and adaptor combination, and all Sony E or FE lenses are fine, as they have loads of spare adjustment (no hard infinity stop – they will all focus way beyond infinity and can handle big differences in camera assembly accuracy). Same with LA-EA3 and LA-EA4 adaptors and Min/Sony A lenses, the worst case lenses hit infinity at exactly infinity, most focus just past.
Kipon Nikon Tilt-Shift – extremely tight fit, so tight it has to pulled off the camera physically. Here I’m thinking that some very gently polishing or ultra fine emery (the sort I use for polishing guitar frets) might ease the adaptor.
Novoflex Leica M adaptor – will not bayonet-lock with the new mount, can’t work out if the flanges are obstructing the full turn or the locking pin hole is slightly off position. Fotodiox helical M adaptor locks perfectly. All other adaptors fit and lock comfortably.
Checked my Kipon shift adaptor for Canon and it’s 21.34mm from rear to front flange, and the lens won’t focus on infinity. My plain cheap Canon FD adaptor is 21.16mm and the lens will hit infinity perfectly. On the original mount, the shift adaptor was just OK to infinity – not for stars, but for landscape. So maybe 0.1mm actual difference in front face register to sensor on the Fotodiox Tough mount, compared to the Sony original.
Light leak issue – a day later I had bright full sunshine and was able to position the camera with the mount getting direct sun, and give exposures of 30 seconds to 1 minute with the lens completely stopped down and blocked off, and the ISO set to 1600. The results proved that it’s not the camera mount assembly which has most effect –
The pure black exposure above is from the 28-70mm kit zoom set to 40mm, at f/25, with the lens cap on.
This result is from a Voigtlander 40mm f/1.4 mounted using a Novoflex Leica M adaptor, at f/22, with the lens cap on. Simply swapping the Voigtlander adaptor for a Fotodiox helical focusing Leica M adaptor, which has a far wider flange and double the ‘bearing surface’ on the mount and it also a much firmer overall fit, produced the same solid black as the 28-70mm. The 10-18mm also produced a solid black though it was clear that the lens cap lets in a bit of light at the spring clip positions.
To double check, I fitted a disc of Rosco Black Cinéfoil (totally lightproof heavy metal foil you can cut with scissors) into another mount so it sat behind the back of a 50mm lens. This was a Ukrainian shift mount and Zenitar lens. This mount also has a large, black anodised rear surface. No light was admitted. I found that most of my third party adaptors let in light, usually the small angled line/crescent top right, and so did the Sony LA-EA3 and 4. The Novoflex has me surprised and baffled as it let light in over a wider pattern, and it seems to be the best engineered adaptor I have, but the well for the bayonet locking pin is shallow and perhaps too precise as the pin does now not engage (you can feel it just begin to hit the lock position).
(don’t read beyond this point if you don’t like seeing measurements…)
This adaptor works perfectly on other NEX/E bodies and worked perfectly before changing the mount. Relaxing and re-tightening the mount fitting screws, to be doubly sure of correct seating, did not solve the problem. The pin recess in the Novoflex adaptor is 2.30mm wide, and in all the other adaptors measured and also on Sony lenses, from 2.36mm to 2.5mm. The slight wiggle present on Sony lenses when fitted seems to be down to approx 0.07mm tolerance allowed for the locking pin to engage, as this is the part of the mount which limits or fixed the position of the mounted lens. Lenses and adaptors tested, when mounted with the locking pin depressed, can move around 0.5 to 1mm beyond the optimal mounting position.
It looks as if the locking pin mechanism is one area identified as a source of light leaks, and that if the pin is not allowed to engage fully (recess too shallow or not accepting the pin) more light will be admitted. All my manual adaptors varied in the depth and exact design of the locking pin well – 1.1mm deep on Kipon, 0.69mm deep on Fotodiox, 1.23mm on Novoflex, 1.1mm on Sony G 10-18mm, 1.18mm on Sony 16-50mm PZ. The 28-70mm which had perfect light sealing also has an unusual locking pin hole, almost perfectly circular not an elongated oval like all the other lenses. This was 1.2mm deep and with a 2.5mm radius. It is obviously perfectly placed and very precise despite this being a non-G, non-CZ, cheap Sony kit lens.
Anyway, 10 seconds with a Dremel and the Novoflex adaptor is now a perfect locking fit ready for another test if the sun comes out again this year.
Sony did say, back in 2010, they would make the E-mount specifications public for all to use. If anyone has information on what tolerances were specified, please let us know!
Update 30/10/14: using a high intensity single LED torch, the Novoflex adaptor problem was eventually narrowed down to light leaking through the mount between high-grade Leica mounts (Cosina Voigtlander, and Carl Zeiss) and the adaptor. Tightening the flange pressure did not cure the fault. No leak is present when using a low-cost Chinese M adaptor on a screw thread lens, which is a firmer fit. The Nokton and Tele-Tessar lenses also show no leak with the Fotodiox adaptor. It’s just an issue with these mounts – probably from the same source, as Cosina assembles CZ Leica mount lenses – and the Novoflex.
Absolutely no light leak can be identified on the A7R body with the new mount fitted. All leaks turn out to have been down to third party adaptors. The LA-EA3 and LA-EA4 give no light leaks, same for all E/FE mount Sony lenses. The Kipon Tilt-Shift (Nikon, $200+) has so many light leaks I can’t map them – every stage of the unit from the lens mount to the body mount, and all the moving parts, admit light; unit dangerously tight on Tought-E mount. Kipon Shift adaptor (Canon FD) admits light freely, especially when shifted. Canon FD plain adaptor, low cost – leaks at body mount. Cheap Minolta MD adaptor – no leaks. Cheap Nikon adaptor – OK at the body mount, lens release catch admits light freely (repaired using black putty compound but ineffective, still leaks light). Cheap tilt MD to Nex adaptor – one strong light leak in mount between some lenses (chrome flanges) and the adaptor, but otherwise light-tight to the body and in its tilt mechanism. Low-cost L39 to NEX adaptor – no problems at all. Ukraine/Kiev/Zenitar 50mm tilt combo – perfect, no leaks in any position. Samyang 12mm f/2 – small local leak at mount (top right crescent issue). 28-70mm FE – absolutely light-tight, no issues. 10-18mm Sony G – ditto, no light leak at all. 16-50mm Sony PZ – no light leak. Tamron 18-200mm – top right crescent issue. Fotodiox Leica M helical, with any lens, no problems. Focus brand Canon EF to FE mount AF adaptor – no leaks. Original 1st gen Kipon 42mm tilt device – no leaks at all.

I’m using my RX10 to report. This camera is my big Sony dilemma. It’s actually all I really need for 95% of my daily work.
Well, here we are reporting from photokina 2014, the major trade fair in Cologne. I’m only here for the day and a brief stop in tomorrow morning en route to the airport, and my first appointment was with Sony. To be frank, it doesn’t matter that much as everything has already been publicised on many web pages. My only request, to be allowed to take some test frames on my A7R using any of the new FE lenses, was turned down because the lenses were ‘pre-production’. I was not pleased to be standing within earshot when, ten minutes later, the very same 16-35mm f/4 was being made available to another UK journalist not only to use but to take outside the hall into the Messehallen surroundings for ten minutes (chaperoned).
Of course you need a Canon sign over queues. It is after all the brand of herd!
I don’t need an outside scene to assess a 16-35mm – give me a room with vertical pillars (plenty) and some small very intense bare bright light sources (ditto) and I can pretty much do an optical test on such a lens in a couple of dozen frames. The good news is that Sony UK may be better placed to let photoclubalpha (and all the other media I write for) have loan lenses. In the last year, I’ve bought £10k worth and sold £5k worth of Sony and related third party gear to be able to keep up to speed with the rate of new products and their sheer cost.
If equipment had cost this much relative to earnings when I set out in photography, I would never have become a photographer – it would not have been possible. It would have been making a choice – a deposit on a house, a secondhand car, or a camera and three lenses?
And lenses are certainly being rolled out. The new roadmap concentrates entirely on the E-mount systems (FE and E, full frame and APS-C). The Alpha 99 may still be there as a flagship for the A-mount but there’s really nothing here, no news, for A-mount system users.
Hands-on reports from photokina often mean nothing more… hands-on! No pictures allowed with the glass. It looks like a lens, it works like a lens, but it’s really only half a lens.
Unless, of course, it is two times a lens. The ciné targeted 28-135mm f/4 power zoom for FE may have the ghost of a Minolta 28-135mm hiding inside its suit of armour. It’s huge.
In a sealed but rather grubby fingermarked cabinet sat the new lenses – a Carl Zeiss Distagon T* FE 35mm f/1.4 ZA, a Sony FE 24-240mm f/3.5-6.3 OSS, and a Sony FE 90mm f/2.8 Macro G OSS. I wiped the drool marks off the glass with my secret weapon (a packet of tissues) and took some individual pictures.
OK, the glass didn’t clean up all that well and there were many reflections to avoid.
But here is what you need to see – a 90mm macro with an external OSS on-off switch so you do not have to menu dive to perform this function when tripod mounting, as well as a triple range focus limiter. But this len is a real monster. We have to assume it uses internal focusing with a design like this.
And here is another surprise. Like Fujinon XF lenses, the forthcoming CZ 35mm f/1.4 has an RX-style third f-stop clicked aperture ring, with an A setting at the extreme beyond f/16. My guess is that there is also an RX-style click disengager round the back, making this a superior lens for ciné but almost certainly needing a firmware update for camera bodies as it is the first A or E mount (electronic aperture) lens to feature an on-lens aperture control.
Then we have a neat 28mm f/2 AF for FE, joining the Carl Zeiss Loxia manual focus, electronic function 35mm and 50mm lenses shown elsewhere on the stand (one day I may feature these if we find them exciting enough).
This lens has two optional adaptors – very much like the adaptors for the 16mm E series pancake, a 0.75X wide angle (converts it to a 21mm f/2) and a fisheye (converts it to a 16mm f/2).
I would say many of the size advantages of the A7 full frame camera series are completely negated by all of these new lenses and by the adaptors. What we actually need and want is a handful of properly compact sensor-matched lenses, smaller perhaps than the existing 35mm f/2.8 FE, and not a range of lenses which increases the overall size of a mirrorless kit to the point that you might as well have a DSLR. It’s not quite that bad, they are still a bit smaller overall, but here’s the 28mm converted to fisheye:
I’ll leave you with the test set-up for the A6000 and lenses –
I’m off for a meeting with Sigma. Just got ten minutes to find them!
