Alpha Silver Jubilee – 25 years 1985-2010

The Alpha System celebrates its Silver Jubilee or 25th Anniversary this month – though left uncelebrated by the inheritors of the Minolta AF legacy, Sony. They have no reason to draw fresh attention to the age of the system, as in four years they have taken it the same sort of distance that Minolta took the world’s first AF system in the late 1980s.

It’s not only Alpha’s 25th birthday. This is also the 25th birthday of modern AF SLR systems – all of them!

This is a multi-page article. See the links at the bottom of the page to Continue Reading after each page.

For Photoclubalpha and the historic Minolta Club of Great Britain, the anniversary does matter. A good many of you out there have been members since the launch of the system, often using the earlier SR and X manual focus systems before that. We still have a 1985 Minolta 7000AF and it’s still working just as it did when new.

25 years before the first Minolta SLRs appeared – a folding Minolta Six of 1935

I don’t mind showing my age to make a comparison. I was 11 in 1963 when I took my first pictures with an SLR camera. My father had bought himself a Pentax S3 – and the camera it replaced was 25 years old, a pre-war Zeiss Ikon Kolibri collapsible 16-on-127 model.

When the Kolibri was made, 127 was the ‘vest pocket’ format of choice. 35mm was on the rise, but 35mm SLRs had not yet arrived. They were as much a thing of the future as digital SLRs were when the Minolta 7000AF was launched.

But within that 25 years, there was hardly a single camera system made with interchangeable lenses that did not become obsolete. Only the ‘frozen assets’ of the cold war kept some systems, like the Exakta bayonet and the Praktina, alive. New brands were launched, from the British Wrayflex and Periflex to the Italian Rectaflex and many German oddities. It was not unusual for an entire system to be come and gone within a few years.

Even in the following quarter-century, the high years of the Japanese 35mm SLR, the succession of lens mount changes was bewildering. Independent lens makers like Tamron and Sigma were forced to make systems using interchangeable mounts not just because the public wanted it. A dozen or more mounts were made for every lens and in the 42mm screw thread fit alone there were endless variants – Praktica LLC (Pentacon Electric), Olympus FTL, Pentax ES and more.

It was more or less a 25-year cycle – the SR system was announced in 1958, and really got underway by 1960. It was to be another quarter century before the AF system arrived. We are now a further 25 years on – can we expect a totally new camera system, once again, in 2010?

Minolta’s SR bayonet mount, introduced in 1958/9, actually remained basically unchanged all the way through to 2005 when the last manual focus model, the X-370S, was available. It survives even now as a mount popular in China where the Seagull range from Shanghai Optical includes Minolta fit models. That mount only ever had one major revision, to add a linkage for open aperture TTL metering. The introduction of programmed exposure and shutter priority was cleverly enabled by using the existing design of lens mechanism and improving its accuracy, while adding a simple reference lug to the ƒ-stop setting ring.

Nikon’s 1959 F-mount proved similarly easy to improve without any basic modification. Both these bayonet mounts celebrated half a century of production in 2008/9 – another landmark, which Nikon was able to celebrate but Minolta of course could not.

Sony Alpha 550 Review: highs and lows

My review of the Sony Alpha 550 was supposed to appear at the end of November, allowing one week abroad in good weather with plenty of subject-matter, in Tenerife. Sadly that trip had to be cancelled, and the Nikon D3S arrived for review on the day we were meant to have travelled. So, with far too much work to do on the D3S, I’m “going to press” here with my initial thoughts based on a fairly short time using the Alpha 550. There are 11 pages in this review, please use the Next Page navigation at the end of each page to continue reading.

PLEASE NOTE: this website uses a rating system where readers can rate the posts, like this review. This rating is NOT my ‘rating the camera’! I have read elsewhere that I ‘gave the camera 4.83 out of 5′ – that was the rating readers gave my review… sorry, this is very confusing, I had not realised how easily it could be confused. We have had the post-rating system for a long time and it’s a standard feature on many Wordpress based sites. I do not want to remove it (along with the ratings) so please accept this apology for incorporating a dangerously confusing ’star rating’ here.

Alpha 850 official press release

Sony has announced the Alpha 850 today, without a press conference, but via email to editors. The press release follows, confirming pretty much everything we have already been able to reveal about the 850. One exception – it does have dual BIONZ processor, not single, just a slower image throughput perhaps due to clock speed, buffer, processing firmware changes. We must hope that the slower capture rate is accompanied by superior image quality, as that is a real possibility. I have marked in bold any phrases which I think might indicate something new. Apparently the body-only deal is to appear one month before the kit.

7fps – marketing point or real benefit?

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.

Sensor-feed Live View in new Alpha 500

ACCORDING to specifications revealed on a German site, the new Sony Alpha 500 will have a 12.3 megapixel CMOS sensor capable of providing Live View to the rear 3 inch medium resolution screen – with Manual Focusing at 14X magnification. The in-prism based Quick AF Live View is retained, giving a choice between two entirely different systems of Live View, Sony’s innovative and easy solution scanning the focus screen, and a critically accurate alternative for tripod work. The camera may sell for just €50 more than the Alpha 380 – or break the £500 body only barrier in the UK right from the start.

ACR 5.5 RC shifts Sony colours – a little

Adobe’s Camera Raw Release Candidate 5.5, which introduces global corrections for all Bayer sensor cameras requiring a differential value treatment between the two Green channels, has a visible effect on the colour of Sony Alpha file conversions.

Crop or cram? Pixel density versus the big view…

The Alpha 900 offers an unrivalled view through its 100% prism finder. The extra brightness, as well as the size and clarity, make most subjects far easier to photograph well. For some users, however, the full frame camera brings a disadvantage in terms of reach and resolution. You need lenses 50% longer (and thus twice the size, and four times the cost!) to fill the frame with the same distant sports and wildlife subjects. I don’t need to remind anyone how popular these two subjects are with amateurs, and sometimes, how important to professionals.

The Sony Alpha 380 – review

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.

Alpha 850 – 24 megapixel 3fps in 900 body

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.

fotobrenner2

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.

Alpha 500, 550 and 850

Sony’s September launch for 2009 looks set to include three new models – the Alpha 500, 550 and 850. The model numbers are confirmed by the usual backdoor leak, appearing in the registration database for SonyStyle USA in this case (Canada has been a past culprit, updating databases associated with their site before the product is officially released). However, only a few people know what these cameras will be, and they are limited by non-disclosure contracts.

The Sigma 70-200mm f2.8 EX DG HSM Macro II

SIGMA redesigned their 70-200mm not long ago to change the EX version to DG, introducing new coatings which greatly improved microcontrast and eliminated digital camera sensor reflections. In 2008, this was further upgraded to the Macro II model with HSM sonic motor focusing, a new optical design capable of focusing down to 1 metre distance. In 2009 this became available, along with matched HSM-compatible 2X and 1.4X converters, for the Sony Alpha mount.

Kodachrome reaches the final frame

LONDON UK, June 22, 2009 – Eastman Kodak Company announced today that it will retire KODACHROME colour film this year, concluding its 74-year run as a photography icon.

Sales of KODACHROME Film, which became the world’s first commercially successful colour film in 1935, have declined dramatically in recent years as photographers turned to other, newer KODAK films or to the digital imaging technologies that Kodak pioneered. Today, KODACHROME Film represents just a fraction of one percent of Kodak’s total sales of still-picture films.

Sony Alpha 230, 330 and 380 update

a3809

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.

Alpha 330 – future model?

Latest update May 7th:

Sony Style pages are starting to show this header picture, which shows three new models all sharing an unusual handgrip design and using the new lenses:

lifestyle_dslr_byseries

Note – the new models have handgrip sensors or appear to – maybe the nickel problem has been conquered. Also note the radical shift in position of the front control wheel and shutter release. The A380 is next to the A900, followed by the A330, and then the A230 at the end. All are smaller than the current A200-300 series. The A330 and A380 have what look like Live-View switches next to the prism, the A230 does not. This indicates that the viewing method has not changed, and we will almost certainly not get off-sensor live view or video. This does not rule out some kind of improved 720p LV of the focus screen, combined with electronically switched markings that could be turned off for recording video ‘off the groundglass’.
