TOKINA lenses – the brand name for optical giant Hoya’s interchangeable range – have always been renowned for their tank-like build quality and resistance to plastic trends. They compare so well with Nikon’s own lenses it is hard to tell the difference by feel, and the current design also matches Nikon more than it does Canon.

The latest news is that Tokina is to introduce the 11-16mm ƒ2.8 in Sony Alpha mount. Tokina stopped making Minolta mount lenses shortly before their parent company Hoya acquired Pentax. The Tokina factory has been producing

In an unusual move, probably designed to cut down the work of rejecting submissions which fail to make the grade, the on-line picture library Alamy has published lists of cameras (by make) which will NEVER produce a file acceptable to pass their Quality Control. It includes all the Sony Cyber-shots ever made as far as we can tell! They say: “Check your camera – do NOT submit any images from camera models featured on the list below. Camera models featured on this list do not produce files that are capable of passing Alamy’s QC standards.”

Sony has announced the Alpha 500 and 550 today with an official release to all press. No press conference was held for the UK press and any advance information received has been given indivudally to journalists. There is a press event tonight in London but this is VERY specifically stated to be for trying out the new Cyber-Shot models at twilight. The official release follows.

ALL the current DSLRs made – whether by Canon, Nikon or even Sony with the A700 and A900 – state their maximum fps continuous shooting speed as being with NO autofocus, and NO exposure metering changes. There’s a lot of talk on forums about the 7fps of the new Alpha 550 – 14.3 megapixel CMOS APS-C with a good high ISO capacity – being in some way crippled because it has been made clear by Sony that this speed applies to a ‘lockdown’ of focus and exposure with the first frame. This is not surprising as it’s a quiet, mirror-up mode using the off-sensor live view to maintain contact.

Tamron’s 18-250mm lens – later adopted by Sony – was so good that it really takes some effort to beat it. Sigma has put that effort in, but the cost is a very much larger and heavier lens. If all you got was some better performance, it might not be all that exciting. But you get potentially superior anti-shake through its built-in OS, and faster focusing with HSM, the Sigma equivalent of SSM.

My Sony Alpha 380 was supposed to arrive before July 13th according to SimplyElectronics.net – via Amazon – claiming UK despatch of 2-10 days delivery after debiting my card on July 6th from a July 3rd order. Well, it didn’t arrive by July 21st, and after some email exchanges I have apparently obtained a refund for the charge they made for an item they did not have (though this was still showing as ‘processing’ in August). Warehouseexpress.com had got the A380 plus 18-55mm kits  by that time, for £10 less, and delivered in 24 hours. Update August 9th: under a month later, the warehouseexpress kit price has fallen by 10% (£50) to £548 inc VAT.

Sony’s new Alpha 850 will be identical to the Alpha 900 in size, handling and external design – including the omission of onboard flash. The camera, expected to be launched before September, uses the same 24.6 megapixel CMOS sensor as the Alpha 900 but has – it is rumoured – only a single BIONZ processor, and a very slightly modified viewfinder. It is shipped without the Remote Commander (this becomes an optional extra) indicating that minimum retail price is Sony’s aim.

This is a screen grab from Fotobrenner.de in Germany who have the body only offered for €1999.00 and the kit with SAM 28-75mm f/2.8 new lens for €2699.00. As listed that makes the body about 10% more expensive than the current street price of the Alpha 900 – indicating either that the A850 prices are RRP and will rapidly fall, or that the A900 is about to get a price hike. They offer the A900 for €2499.00 and that would – pro rata – make the UK street price for the A850 about £1599. Please note: though the 28-75mm picture is authentic, the body shown has the AF switch set to C – just like the Sony shots of the A900 issued to dealers. Maybe they would do this for all packshots for some reason, maybe it was chance – more likely. It would be unlikely to happen again for the 850 shot so I reckon this is shopped.

A long-demanded 1.15X eyepiece magnifier – compatible with all APS-C format Sony Alpha DSLRs – is just one of a rollout of new minor accessories for the system. The Magnifying Eyepiece FDA-ME1AM is designed to fit the A700, A380, A330, A230, A350, A300 and A200 and should also be fully compatible with A100, Konica Minolta 7D and 5D.

All of Icon’s professional Master Photo Digital magazines can be read free on line. The latest, June 2009, has just been published:

This magazines uses the same Flash Reader format as the 19 editions of Photoworld and – NEWLY ADDED! – five editions of Minolta Image from the 2002-4 period just before Konica moved in. We have been able to find complete, or very nearly complete, original archive files for these issues and create PDFs to convert for our subscription service.

Photoclub Alpha’s Photoworld quarterly magazine is now available as an on-line subscription without printed paper issues (you can print any pages you want from the Flash-viewable ‘book reader’ format editions, read on-line, or download to read when you like). The cost is just £10.00 per year and gets you the latest issue before it even reaches our susbcribers!

The five editions of MINOLTA IMAGE from 2002-2004 take the archive back to December 2002 with 23 past editions of the club magazine available to read. Your £10 now gets you over 800 pages right away.

You don’t even have to keep checking the site, you are sent an email anytime we add a new edition – or add to our archive of back issues. Already there are 19 issues of Photoworld covering from Spring 2004 to Spring 2009 – the entire history of the Alpha digital system from the Konica/Minolta merger onwards. That’s over 500 A4 pages of reviews, news, tests, portfolios, galleries, how-to-do-it and inspirational articles. To preview what’s on offer (see the covers, contents page and first couple of pages of each magazine free) click the link then click any cover thumbnail. You’ll get a preview of four pages, and the choice of a full subscription or the single issue price of £3.

Here are two comments from readers:

“The current Photoworld copy I received yesterday again is of outstanding quality. It is easily the thinnest magazine I read in terms of mm width, yet content and printing quality are reason for great delight. The printing is so much better then any of the magazines for sale in Germany, it is breathtaking every time.” - Markus Spring

“The best ten quid of any Minolta/Sony owner’s money has to be on YUDU, right now. I have just paid (through PayPal) and have access to every copy (it seems) of Photoworld magazine from early 2004. That’s 19 editions and the on-screen presentation is fantastic, not to metion the opportunity to download and read offline. I love magazines, I especially love photography magazines, and to be able to read the back catalogue of Photoworld is an absolute steal for that price.” - Brian Young

This post has been updated on August 29th as it features second in Google searches for Sony Alpha 550 – but it contained only rumour links when first posted in May.

The camera is now launched, along with the 500 and the full-frame 850.

The new Alpha 230, 330 and 380 models are radical ergonomic redesigns of the existing 200, 300 and 350 series. There is a 15% reduction in size (volumetric) and weight, an update to the styling, and a completely revised user interface with graphic representation of setting adjustments – with a built-in ‘handbook’ to accompany the modes and options. They also have mini-HDMI image output, compatible with Bravia TVs and with interactive software inside the camera to allow the Bravia’s own remote control to change, orient and zoom into images (Bravia Sync). Twin card storage is MS ProHG Duo/SD and only one card is usable at a time, with a hardware switch to change slots. A smaller battery type (shared with the HX1 Cyber Shot) is used. A new self-timer drive mode grabs a quick burst of 3 or 5 frames, cutting the chances of spoiled portraits and groups shots when someone blinks at the wrong moment.

The new flashgun HVL-F20AM operates as a wireless flash controller for the full-frame α900. “While Sony’s flagship DSLR does not have its own integrated flash, the HVL-F20AM can be used as an inexpensive trigger for wireless remote flash heads” according to Sony UK.

Canon has announced a consumer level EOS 500D camera, with 1080p resolution video limited to 20 frames per second, and 15.1 megapixels but a maximum shooting rate of 3.4 frames per second:

http://www.dphotoexpert.com/2009/03/25/canon-eos-500d-151-mp-plus-hd-video/

This continues the trend for all new DSLRs to have HD movie shooting in addition to live view modes, something which Sony to date shows no sign of catching up on. However, the obvious compromises present in the 500D would be criticised harshly if they were to have appeared first in a Sony model, so this is good news. Canon has made it acceptable for others to follow with 20fps instead of the required 24fps, and still claim true 1080p video.

There is a white paper by Sony Semiconductor on the imaging processing which I think is in the HX1, http://www.sony.net/Products/SC-HP/cx_news/vol55/pdf/featuring55.pdf. I assume it is the IMX-032 CMOS sensor (http://www.sony.net/Products/SC-HP/cx_news/vol55/np_imx032cqr.html) mated to a CXD4109AGG image processing chip. There seem to be some interesting techniques employed, multi-plane synthesis to combine several frames for low light and HDR capture.

With the IMX-032, it is interesting to note that the on-board programmable gain amplifier has a gain value of up to 18dB or a factor of 8, so if base ISO is 80, then maximum “analogue” ISO is 640. If we compare the IMX-032 versus Sony’s first column ADC CMOS chip (IMX-017), the IMX-32 has an 11.8% better photo-electron efficiency per unit area (2300e per 1.75 micron square pixel compared to 4500e per 2.5 micron square pixel). Might be a sign that Sony is improving the process and design used to make their CMOS chips.

The backside illuminated chip is called the IMX-061, http://www.chipworks.com/uploadedFiles/Aliased_Pages/CMOS_ImageSensors_Spotlight/Chipworks%20-%20Sony%20IMX061%20EXR-0902-813.pdf
6MP and 1.75 micron pixels in ClearVID (45 degree) layout with a 1:6:1 RGB Bayer filter array, sacrificing colour resolution for spatial resolution.

The Nikon D90 chip is called the IMX-038 (not the IMX-021 as for the A700), so this suggests it has significant revisions compared to the IMX-021 (possibly linked to LiveView and HD Video?).

SONY has, one week after the leak of a final version of Firmare v4 for the Alpha 700, placed authorised download links on their support websites along with an updated Image Data Suite 3 which can handle Alpha 900 raw files. Quick download links are given here with key features.

Canon has today officially announced the 15.5 megapixel APS-C EOS 50D. This is a 1.6X factor sensor, packing a density well in excess of the Alpha 350 – if Sony was to make an Alpha with the same pixel density it would be 17.5 megapixels, and a full framer would be 38.5 megapixels.
