Photoclub Alpha

The parallel development of Carl Zeiss lenses for Sony (AF lenses in the Alpha mount) and independent manual focus lenses for other makes continues. The latest CZ design is a revision of the classic 18mm Distagon last seen in the Contax system, optimised for colour balance and reflection supression with digital SLRs.

Increases in pixel count are often dismissed because to ‘double’ the resolution of a 6 megapixel sensor you would need 24 megapixels. Indeed, to double it linearly you would - but the human eye judges density of detail on an area basis.

Here’s a question which came in to my email just now:

“Could I process a RAW file in Photoshop to achieve a similar effect as if I had used a Polaroid lens filter?
Or would I be better just using the Polaroid filter?”

The answer is that you can never imitate the effect of polarizing light (which changes the way reflective surfaces look, and deepens or lightens the sky blue according to the zone of the sky relative to the sun’s position. But you can use Adobe Camera Raw (CS3 versions) to deepen skies you never thought could be rescued.

The introduction of a £399 (street price, RRP £449) DSLR with 14.2 megapixels – with or without a useful type of Live View – should have been applauded by reviewers. It’s the single most important point about the camera. No other DSLR approaches this image size and resolution at such a low price.

Our cover photo for the Spring 2008 issue of Photoworld was taken with a Tamron 70-300mm zoom costing less than £120 from most larger retailers or internet shops. The reputation of the lens meant we had to take a look at it, because the current choice in the Sony range is limited to one ‘kit’ 75-300mm costing £179, and the new 70-300mm G SSM lens costing £600.

Now that there are five Sony Alpha DSLR bodies in circulation, with many owners of the original 2006 Alpha 100 considering a replacement, the differences between this ur-Alpha and the 2007-8 generation of Alpha 700, 200, 300 and 350 need examining.

Our Spring edition features -

The Sony Alpha 350 14.2 megapixel DSLR pioneers a new type of Live View, related to Olympus’s original Mode A of the E-330 where a beamsplitting arrangement allowed a video CCD to view the actual focusing screen of the SLR system.

There’s a lot of controversy right now about whether or not the image structure of the Alpha 700 files at very high ISO - mainly 3200 and 6400 - is as clean as raw processed results from other comparable cameras like the Canon 40D (does not offer ISO 6400), the Olympus E-3 (does not offer ISO 6400) or the Nikon D300. At the heart of this is the way different raw processors handle file conversion, and most specifically, the current performance of Adobe Camera Raw 4.3.1.

The Sony DSLR A200 is now on sale, following the end of Alpha 100 production. Although it is without any doubt the Alpha 100 replacement mentioned by Sony executives in October 2007, when they first revealed that the 100 was no longer being made, it is not an exact equivalent and represents a mixture of upgraded performance and simplified specification. Because it has gone in two directions at the same time, the A200 poses a problem for A100 owners.

Apple’s Aperture 2.0 is a tedious program to test, with all its creation of ‘projects’ and ‘libraries’, ‘albums’, ‘vaults’ and nonstandard GUI, and it isn’t fast in processing files or passing them to Photoshop (which it does in 16-bit form, just another step to reverse before saving as far as I’m concerned). However, it’s handling Alpha 700 raw quite well. And it does things differently, with non-destructive raw editing, stacks of image versions, and so on.

The latest full release - no longer Beta, and accepting previous C1 Pro activation keys for unlimited access but otherwise now on 30-day trial - of Capture One v4 now handles Sony Alpha 700 raw files and transforms high ISO rendering in comparison to the industry standard Adobe Camera Raw.

NOT everyone will want the live view offered by the A300 and A350 - it does turn out to be more or less as we suggested, a secondary optical path adjacent to the eyepiece inside the prism housing. I’ll explain here exactly what the implications are, and why a future model - let’s call it the A500 - offering the 14.2 megapixel sensor without the live view may be worth waiting for.

We have a Photoworld day in Edinburgh on February 10th 2008, to which all Photoclubalpha registered members are welcome (it is strictly by prior arrangement, so please do not turn up on the day). It starts at 10.30am and ends around 4.30pm, and will be held at Edinburgh Photographic Society. There is a small fee for refreshments. Details follow.

Sony say that the Alpha 100 has a 230,000 pixel rear screen and the Alpha 700 has 920,000 pixels. What they don’t make entirely clear is how many individual R, G or B pixels are used to create each ‘pixel’ of the image (complete RGB). In fact the 920,000 pixel screen is VGA - 640 x 480 - in display resolution, which is 307,000 pixels not 920,000. What is going on? We took some macro images to show you.

A mention of 16mm Minoltas reminded me that a few years ago I found a perfect kit - without outer box or instructions, sadly - at an antique fair. A daylight developing tank for the film turned up in the closing-down stock from Konica Minolta’s warehouse. I decided they should really find a new home together via the normal eBay route, but before they went, a studio shoot was needed to record them for our virtual museum.

On January 5th, Photoworld was lucky enough to be able to attend the dress rehearsal and official photo-call for the new Cirque du Soleil production at the Royal Albert Hall in London, and to put the Alpha 700 through its paces for high ISO fast action stage show capture. This article with large reproductions of the images appears in our Photoworld issue due out later in January.

AT THE Consumer Electronics Show, Las Vegas, Sony has announced introduction of the new Alpha DSLR-A200 camera which has been the subject of some strange speculation but was known beforehand to be a replacement for the Alpha 100. This is the first time a DSLR has been launched to the world at this show, and Sony’s decision to do so sends a major signal out as to where they see themselves and the Alpha system in the marketplace. It is highly competitive in price and we have just ordered our body for £369 including VAT (£314 + VAT) plus £13 express shipping from www.sonystyle.co.uk. This is exactly the same price as we paid for our last Alpha 100 in summer 2006.

After reading Andrea Nivini’s article in Italian Tutti Fotografi, December 2007, which launches an attack on Adobe’s Camera Raw plug-in and its handling of many camera types - but specifically, the Sony Alpha 700 - I decided to check out whether the December 5th release, ACR 4.3.1, fixed the problems.

OUR local dealer, Hector Innes in Kelso, used to be a totally Minolta-dedicated retail shop. Hector and his son Alastair have always been Minolta photographers, and Alastair currently uses the Dynax 7D as weapon of choice for weddings. Their shop is one of those few remaining which combines a professional studio (ABIPP, in Hector’s case) with processing and printing, and retail. On the wall there’s a Minolta clock from two or three changes of logo ago, and on the counter, I found a well-used and yellowed Minolta lens chart mat.

I HAVE set up a pBase gallery with a large number of comparison studio shots, all the way from ISO 100 to the maximum, using the A700 and Nikon D300. It has some minor discrepancies in shooting conditions which I need to explain to anyone visiting the gallery.

LET’S not get too acronymical about all this… or indeed moanious! After posting today’s earlier piece on DRO Advanced, I’ve been asked for some further examples of the potential for processing the raw file using Sony Image Data Converter, which includes DRO. Or so it says on the box.

BEFORE we publish a fuller assessment of the Sony Alpha 700, here is a taster of just one improved function, the Dynamic Range Optimisation (DRO) system built into the camera. For social, wedding, sports, music, theatre, news and event photographers DRO Advanced Manual settings are a real magic bullet zapping the bugbears of excess contrast, poor lighting, and inadequate flash penetration.

Sony has released a firmware update for the Alpha 700, from version 1.00 (as supplied) to version 2.00, and an updater for Image Data Converter 2.0 SR.

I’m still testing the Alpha 700 and still struggling with aspects of image quality, notably the failure to get much wow factor from straightforward shots in good light. It seems easy enough to get exceptional high ISO images, of the type they are expected to be, but even then many examples seen are marred by a very coarse noise structure.

Online trade photographic supplier www.photomart.co.uk is to hold a bumper day of photo workshops in its huge London showrooms on November 28, 2007. Billed as an “Anniversary Day”, the day-long programme of workshops is to celebrate the second anniversary of the opening of this major photographic venue.

ON OCTOBER 10th I left the UK London press launch complete with an Alpha 700 review camera. I’ll be covering the many aspects of the Alpha 700 performance in later reviews, but this camera is so good I wanted to get just something out to you right the next day.

THE ALPHA 700 cameras tried in Italy by press representatives, including Paul Olsen of Dinside Data in Norway who sent us the raw and JPEG files for the image used here, may or may not have been pre-production samples. Some cameras which were felt to be poor had over 1,000 exposures recorded before the event. Olsen’s camera appears to have been new, recording frame counts in the 40s during his shoot, and may be a final production sample rather than one of the much-used demo bodies.
