Photoclub Alpha

Alan Hess is the author of a new field guide to using the Sony Alpha 700, published by Wileys, with 281 pages and the usual contents covering basic photographic techniques as well as the camera’s operation.

The cost of the guide is 16 Euros by mail order from Research & Markets of Dublin website; the title is ‘Sony Alpha DSLR A700 Digital Field Guide‘.

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.

Sony has announced the September introduction of the most powerful flash yet for the Alpha system, which incorporates a brand new body design allowing optimum bounce flash illumination regardless of how you hold the camera.

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.

Following announcements that Sony has developed a backlight technique to enable extremely low noise exposures, we receive this press release which may or may not be related - a Sony CCD astrophotography camera capable of one-hour exposures and programmed sequences. Resolution seems a bit basic though.

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.

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.

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.

Today I took delivery of a Sony 70-300mm f/4.5-5.6 G SSM lens. There is no doubt this is the best built Sony SAL lens I’ve handled (the CZ 135mm 1.8, 85mm f1.4 are a class above again). It weighs over 800g with its lens-hood, which is one of the most efficient deep tele hoods I’ve seen.

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 first SONY World Photography Awards were presented in the late April sunshine of Cannes, to what must have been an exclusive gala dinner audience - at €250 a head, our ‘man on the spot’ Thomas Goseberg decided against the opportunity to take his wife out for a quiet meal…

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.

The launch of the Alpha 350, with its small 0.74X viewfinder, makes a proper eyepiece magnifier attachment an essential addition to the Sony accessory range. Olympus, Nikon and Pentax all have such magnifiers, which permit a full view of the screen for most wearers and make all the difference to the manual focusing and general comfort in composing shots. We tested two devices, one of them the highly affordable Seagull 1x-2.5x right angle finder, and the other Olympus’s ME-1 1.2X ocular magnifier.

This is the latest press release from Sony UK - filling the streets of Miami with club-style foam for their new digital photography ad campaign:

London— April 2, 2008 — Adobe Systems Incorporated (Nasdaq: ADBE) today announced Adobe Photoshop Lightroom 2.0 beta, a public preview of new and improved functionality to be delivered in the next major release. Lightroom is the professional photographer’s essential toolbox, providing one application for managing, adjusting, and presenting large volumes of digital photographs. Lightroom 2.0 beta will feature enhancements such as dual-monitor support, localised dodge and burn correction and will be the first Adobe application to support 64-bit for Mac OS X 10.5 Intel Macs and Microsoft Vista 64-bit operating systems.

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.

Kenro has announced the release of a series of new hard plastic LCD panel protectors from Marumi - including one for the Sony Alpha 100. The price is very reasonable at only £6.99 retail.

Moving a DSLR - preferably without vertical grip because of the further imbalance created - to portrait format shooting on a small tripod ballhead produces an unstable arrangement where the head is stressed. The camera may sag unless the head is tightened, and if the lens is heavy, it may also unscrew itself from the normal tripod bush tightening. A L-bracket is the ideal solution for mounting your camera for a portrait session or any other situation where most of the images will be vertical.

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.

The prototype ‘Flagship’ Alpha DSLR, with its 24 megapixel sensor, may offer live view - almost certainly off the sensor. Sony prototype (it is still officially in that state) product photographs reveal what looks like an extra button or sliding switch - and at least one rumour states that this is definitely for live view.

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.

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.

Sony Europe’s Recording Media & Energy (RME) division today announced a new LTO-4 photo contest promotion that offers the chance to win one of three digital cameras from Sony – in return for creative pictures of LTO-4 tape cartridges. The competition can be entered by distributors, resellers and end-customers of Sony’s LTO-4, its highest capacity media.
