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.

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.

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.

My first tests with the Canon EOS 500D were posted on dphotoexpert.com, but given the number of search engines now flagging up this site for Canon 500D searches, I’m putting this post here as well.

This is an edited selection, shot in a mixture of 1080 and 720 modes, assembled using iMovie and written as a 720p final project for YouTube. Please feel free to link directly to the YouTube vid or to this page.

It’s been a marathon exercise – all 18 editions of Photoworld, from the time of the Konica Minolta merger to our last (January) back issue, have been converted to a really great readable format (using Flash Player) which you can view via your web browser, print out or download for off-line reading. We have now added five more earlier editions of MINOLTA IMAGE, taking the archive back to December 2002 – plus two compendiums of reviews and articles from our other magazines.

The cost to access all these back issues – over 750 pages, fantastic portfolios, technical reports and tests covering the entire history of the Alpha digital system – is just £10 (by Paypal) and also gets you a full year of new Photoworld issues in advanced of the mailed copy. Or instead of it, if you prefer to subscribe this way. £25 now buys the postal magazine subscription plus the e-version and archives, worldwide.

There is no need to dismantle the mount of the original series Sigma AF TELE 400mm f/5.6 lens, to bring non-functional versions (old chip) up to speed with later film and current digital SLRs. The whole process takes under five minutes, and requires two tools – a small Philips screwdriver, and a precision end cutter.

SONY’s stand was a real brightener for Focus. Gone were the black and orange colours I criticised at photokina, which for two successive years created a black hole compared to Canon’s oasis of light. Instead, huge white silks extended to the roof with bright spots and floods creating an inviting zone of pure light. White and orange rules!

SONY has a stand at Focus on Imaging in the UK after an absence of three years for the Alpha brand from this major annual photo fair, said to the be largest national show in Europe with the exception of photokina. On Stand L28 – right next to the Canon exhibit – the UK’s technical sales executive Paul Genge has lined up a nonstop programme of speakers and demonstrations.

After just a short while working with full frame, high resolution DSLRs the need for tilt lenses has really come home to me. Most lenses deliver their best results at fairly wide apertures like f8, it’s easy for detail to begin to look soft and lacking impact if you are forced to stop down to f22 to get everything sharp. Tilt adaptors and tilt lenses solve the problem. This article is repeated here after originally appearing on dPhotoexpert (and similar instrument images, in my first D3X test report for the British Journal).
