Photoclub Alpha

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.

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.

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.

This information is from the Sony UK website with some explanatory additions.

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.

IT IS very difficult to find a good JPEG from the Alpha 700 pre-production model tests shot in Italy, because too few cameras were available for too short a time - and many of the journalists present were not photographers. But we have found one image you will love.

PRODUCT shots of the Sony Alpha 700 have been released, and are shown here to our standard web page size of 600 pixels or smaller.

TEMPORARY website pages on the afternoon (GMT) of September 5th managed to leak the entire specification sheet and several new PR images of the advanced amateur Alpha model, along with its name - the Alpha 700. You wouldn’t pick a wife or husband on the basis of their on-paper specification, so remember, the only way to partner up with a DSLR and be happy is to try it in your hands first.

With only three days to go before the launch of the new Alpha, rumours of a ’sneak preview’ press release have appeared on dPreview’s internet forums. Leon van Bommel, writing from Holland, says he has seen a magazine which has a photograph showing the camera with a kit lens marked 16-105mm f/3.5-5.6. Certainly, a more expensive body than the A100 would look out of place wearing the $99 18-70mm f/3.5-5.6 kit lens which is the only cheap option now.

A review by David Kilpatrick from Photoworld Spring 2007 with additional updates

MY SONY Carl Zeiss 16-80mm “superzoom” arrived from Warehouseexpress - the best price I could find and one of the very best dealers in terms of service - packed rather minimally for a £465 purchase.
