Photoclub Alpha

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.

It’s not going to be long before we see the Alpha 900, and some cameras are known to be out there on trial in the hands of Sony staff and pre-release testers. I am not one, so rest assured, this is not a leak! What can you expect from the Alpha 900’s full-frame prism finder?

The latest release of Adobe Lightroom, v2, handles all Sony Alpha and earlier KM digital camera raw formats including the Alpha 700, 200, 300 and 350. It is also updated, along with the final release of Adobe Camera Raw 4.5, to handle Nikon D700. Because Canon appears to have left their filetype identical to the A400, their new 1000D was recognised immediately by ACR even in 4.5 beta version.

This article was originally published in Photoworld magazine April 2008. It discusses the reasons for choosing between the 18-70mm, 16-105mm, 16-80mm, 18-200mm and 18-250mm kit lens choices for the Sony Alpha DSLR system and has been updated from the original text.

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.

CLICKING on key mapping points of a face, then adjusting some simple overlaid Bezier curves using movable anchors, it takes only a minute to load a typical headshot portrait into Portrait Professional.

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.

USERS of the Nikon D3 downloading the latest firmware update have found information strings referring to the D3X and listing the file sizes the forthcoming camera will produce. The sizes match the pixel count of the Sony full-frame CMOS sensor due to be used in the ‘Alpha 900′ Sony full-frame body.

Adobe has released updates to Photoshop Lightroom and the Photoshop Camera Raw plug-in, both available immediately as free upgrades for existing users. The releases provide added raw file support for nine additional digital cameras, including the Sony Alpha 200 (already supported by 4.3.2 whether they knew it or not), Alpha 300 and Alpha 350. Lightroom 1.4 also provides updated printer driver compatibility for Apple Leopard Mac OS X 10.5.

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.

Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

In mid 2007, rumours of a 14.8 megapixel Sony sensor came from the usual Far Eastern ‘inside’ sources. As a full-frame Alpha model (the so-called 900) had been previewed at PMA 2007, it was possible this megapixel count related to full frame, or near-full frame. It now looks as if it may have been a leak of development for currently rumoured 14.2 megapixel (active) Alpha 350, which is an APS-C sensor camera.

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.

SINCE September 2007 I have had for test the Canon EOS 40D, Sony Alpha 700, Nikon D300, Olympus E-3 and Nikon D3 in that order. The reports have been published in the British Journal of Photography, and later on in Master Photo Digital and f2 magazines (some are yet to appear, in February, in these titles). My own system is Sony Alpha but I have to be as objective as possible when field testing all makes. I also have to seek out the unique selling points, the reasons for owning any given model, rather than just compare them on a tick-chart feature basis.

With the Alpha 200 about to appear, I guess it’s time to sum up what I think about the Sony Alpha 700 and how it compares to the competition.

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.

It’s the same on every web forum - if you post a digital picture which would be acceptable to a photo library or professional buyer, half a dozen grumpy one-liners will come out saying ‘That don’t look sharp to me’ or ‘there must be something wrong with your XXX’ (fill in D300, A700, E-3, D3, 40D as required). Then someone posts a hugely messed up image and people say ‘Wow! What sharpness!’…

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.
