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.

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.

Thanks, everyone, for the over-the-top and sometimes very funny support thread on dPreview. I am only on a one-week ban, and for three days of that I was visiting my mother (96, and not entirely sure who I am most of the time). Three days and 800 miles for a couple of hours in a nursing home, and an intended workout for the 70-300mm SSM G at two or three locations on the round trip.

Well, someone got into Wordpress and hacked the page which I wrote on returning, removing its entire content, and replacing the first letter (I) with:

><span style=”overflow: hidden; position: absolute; height: 0pt; width: 0pt;”><a href=”http://kvantservice.com/”>компютри</a></span>

So it must be redone (I can’t locate a Google cache for the page) and I must now consider how the latest Wordpress version can be that vulnerable. I guess it’s always possible to find someone in Bulgaria (thanks for correcting me - not Russia!) who will mess up a web page for a few dollars.

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.

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.

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.

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.

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.

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.

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.

Adobe has posted updates to Photoshop, Lightroom, and the Photoshop Camera Raw plug-in, both available immediately for download on Adobe.com. The updates provide raw file support for 14 additional camera models and camera backs within Lightroom and Camera Raw, including the Sony Alpha 700. Links here.

DxO OPTICS PRO 4.1 is the latest version of a clever raw file processor which includes lens lookup tables to auto-correct distortion, vignetting and chromatic aberration. It also lets you alter the look of Dynax or Alpha images so they match popular films - or other DSLRs by Canon and Nikon!

There is now an excellent PDF format e-book written by Gary Friedman as a user guide, mine of information and all-round treasury of inspiration for Alpha 100 owners – see www.friedmanarchives.com for details and how to buy this either as a physical printed book, or a download. It’s nearly 400 pages but very easy to read on-screen, and the expensive printed edition (even more so if you use your own inkjet!) is not necessary. Gary also has a Dynax 7D/5D book, and Dimage A1/A2 book (equally applicable to the A200).

There’s a new e-book in for the Alpha 700 as well on this site, and Gary has been busy shooting with it in the Autumn season!
dPreview

dPreview is recognised as one of the most important camera test sites on the web. While some visitors complain of bias, we do not believe that is the case, and Phil Askey’s test report on the Alpha 100 while missing a few minor plus points is very fair. This report also shows that the Sony Alpha 100 has (and still has) the highest extinction resolution of all the 10.2 megapixel class DSLRs.

Read Phil’s review.

Phil has also done a review of the Alpha 700.

Raw converters

Sony Alpha owners will find that Adobe Photoshop CS2/3 and Photoshop Elements 4.0/5.0/6.0 include a good .ARW raw file converter in the current version of Adobe Camera Raw 3.x/4.x (anything later than 3.4 will process Alpha 100 .ARW files, 4.3 or later is needed for .ARW2 files from the A700/200 and is much improved over the first compatible version, 4.2, so upgrade your installation if you are still using 4.2). Earlier versions will not handle Alpha files.

You can also convert .ARW raw files from the Sony Alpha 100 into Adobe .DNG (Digital Negative) universal raw files, readable by earlier versions Adobe Photoshop 7, CS and Elements 3. Please note that downloading auto-updates for Photoshop does NOT automatically update the raw converter, and this must be done as a separate, manual download. There are two download options, both entirely free, for the DNG converter and the ACR 3.x/4.x plug-in (which requires CS2/3 Mac/PC; or PSE 3/4 for Mac, PSE 4/5 for Windows; and is not compatible with earlier versions):

Adobe Lightroom, a dedicated raw file conversion and ‘digital asset management’ utility, which is a complete stand alone product including A100 conversion, can be purchased from:

http://www.adobe.com/products/photoshoplightroom/

There’s a great Mac-only raw file developer for the A100, A700, A200 and previous Konica Minolta DSLRs - RAWDeveloper from Iridient. This is really fast, allows scaled exports, has superb noise reduction and is a highly professional workflow solution.

Another alternative is Silkypix Developer Studio, a Japanese developed raw file converter, which has something in common with Sony’s Image Converter SR, and will - again - handle both the new A700/A200 and A100 file formats and previous Minolta and Konica Minolta raw files, for those with mixed systems. This is available in both Windows and Mac versions.

Bibble, a popular commercial multi-format raw converter and browser utility, now supports the Alpha 100/700/200. We have had some problems with scaled-up output showing unwanted raster-like patterns, but for normal size files BibblePro offers NoiseNinja which is one of the best ways of dealing with the Alpha 100’s rather strong high-ISO noise levels.

DxOptics Pro also now supports some Konica Minolta/Sony DSLRs and includes automatic correction for a few Minolta/Sony lenses. This deals with chromatic aberration, fringes, curvature of lines and vignetting of brightness towards the corners of the field, and it is especially useful with digital format zooms. They do not appear to have fulfilled the promise of serious support, and are concentrating on the obvious cashcows of Canon and Nikon ownership percentages. The Alpha 700 was not supported last time we checked.

An excellent top-level raw .MRW/.ARW converter, if a little hard to master, is Capture One Pro made by Phase One, the Danish digital medium-format back manufacturer. The good news is that if you buy a SanDisk Extreme III memory card right now (as from October 16th 2006) a version normally costing $99 called CaptureOne Pro LE is included on the card free of charge. You can also download trial software, and upgrade this LE version to the full product, by visiting Phase One’s website. The latest Beta 4 version is remarkably unstable and still doesn’t support all the newer cameras.

Recently, a Mac-only converter came to light, RawPhotoProcessor. This is simple and deep. It reveals a lot about the image through reading the makernote and metadata comments hidden in each file. It is fast and small. It has no noise reduction beyond simply chroma blurring, and no sharpening option.

Another commercial program we really like - it has a very good interface - which works well with the 5D, 7D and A100 but awaits A700 addition is LightZone from Lightcrafts Inc. This is a feature-laden full image management system which can match Aperture or Lightroom on most levels and even replace Photoshop for some work.

http://www.lightcrafts.com/download/download.html

This program is not very well marketed internationally, yet. Of all the commercial offerings it has the most potential, I think, for cross-platform universal application.

A good PC-only raw converter, small enough to run on palmtop devices and Origami platform machines, is RawTherapee. This independently written experimental converter has won many converts amongst Alpha 700 users, as it offered support right from the start and overcame most of the smurrging issues present in high ISO detail:

Let us know of any other raw converter links, and I will add them.

Support and resources< For legacy support and information on Konica Minolta photo-digital products, we currently recommend the website below, which has not disabled all its downloads of software, firmware, etc: http://ca.konicaminolta.com/support/americas/

For information on the Sony Alpha system and the new Sony Alpha 100 DSLR, the UK Sony site now has some really excellent resources in place. Use the High Bandwidth option if you possibly can, and expore both ‘Assignments’ and ‘Equipment’: http://www.sony.co.uk/nextlevel

The bimonthly magazine for freelance photographers, Æ’2 Freelance+Digital, has a dedicated website where many PDF articles can be downloaded. We have included on this site many PDFs from our Photoworld magazine. Æ’2 magazine moved to new publishers from the October/November 2006 edition, but our website remains operational. Registration is necessary but paid subscription is only required to access the archives of older articles - new editions are free for two months to all comers, subscribers can download from well over 100 previous articles: http://www.f2photo.co.uk/

You can view a selection of full size, 10.2 megapixel images taken with the new Sony Alpha 100 on David Kilpatrick’s pBase pages. At the last count there were over 70 examples and the Alpha images had clocked up over 100,000 views. There’s lots of technical information on the tests, examples, and comparison present on these pages. These include comments, captions and EXIF shooting data: http://www.pbase.com/davidkilpatrick

There is an independent Minolta M-AF forum and website, Dyxum, which offers many useful resources including lens tests and storage card speed comparisons. Unlike dPreview, Dyxum does not ban participants for being associated with specialist websites like Photoclubalpha, and has kindly promoted and helped us in the past: http://www.dyxum.com

Yahoogroups include one dedicated entirely to Minolta which in practice is used by Sony Alpha owners as well - http://groups.yahoo.com/group/Minolta/. There is also a Yahoogroup called SonyAlpha, at least until Sony’s legal dept ask them to cease and desist: http://groups.yahoo.com/group/SonyAlpha/.

A busy forum is well established at Dynaxdigital - http://www.dynaxdigital.com/

Carl Garrard and T E Morrison have set up a site called Alphamountworld which offers forums, reviews and articles and will be reporting from major trade shows in the US. Carl is also going to post articles from his show visits or press invites to Photoworldalpha.

A useful group with a strong photography emphasis is UKExpert - forums and galleries and many further onwards links. It was a pleasure to meet Andy from UKExpert at the Sony Alpha 700 launch, and great to know that Sony value the presence of independent opinion-formers.

There is a photo sharing site (by far the most popular web activity for photographers!) at Shootalpha.com. This is, after all, what camera clubs and even august professional associations do - share their pictures and pass generally not unkind comments on them to each other, with the occasional bit of constructive crit. Do not expect to encounter the photo equivalent of Simon Cowell stalking the gallery pages, you will be welcomed as a beginner and find your level quickly. There is also an active forum.

Dealers and spares

The main Icon Publications Ltd site allows subscription to Photoworld magazine, including special offer options with free gifts (subject to additional postage & packing only). We also have a range of discontinued Minolta products for sale, some Alpha-compatible, and details of our other photo magazines: http://www.iconpublications.com/

Former Minolta Club administrator Adrian Paul has his own specialist business selling spares, accessories and smaller hard-to-obtain products from the Minolta and Konica Minolta ranges, and will be offering Sony Alpha system products in future. The Photostore is a mail-order business only and Adrian offers a fast, excellent standard of service and knowledge: http://www.photostore-uk.com/

Lens rental is also available from the Photostore in the UK, but applies only to Photoworld magazine subscribers, and full details are printed in each magazine. There is a new Alpha lens rental service operating in the USA - http://www.alphalensrental.com/index.html.

Pro dealers Calumet have the Alpha system now as a main line, after decades of sidelining the Minolta mount. This is very important and will put the Alpha in front of Britain’s working professionals: http://www.calumetphoto.co.uk/. Sad news is that in January 2008 they sold off a lot of stock at half price because it had not been shifting well enough.
