Alamy blacklists compact and bridge digitals

Posted on By

In an unusual move, probably designed to cut down the work of rejecting submissions which fail to make the grade, the on-line picture library Alamy has published lists of cameras (by make) which will NEVER produce a file acceptable to pass their Quality Control. It includes all the Sony Cyber-shots ever made as far as we can tell! They say: “Check your camera – do NOT submit any images from camera models featured on the list below. Camera models featured on this list do not produce files that are capable of passing Alamy’s QC standards.”

7fps – marketing point or real benefit?

Posted on By

ALL the current DSLRs made – whether by Canon, Nikon or even Sony with the A700 and A900 – state their maximum fps continuous shooting speed as being with NO autofocus, and NO exposure metering changes. There’s a lot of talk on forums about the 7fps of the new Alpha 550 – 14.3 megapixel CMOS APS-C with a good high ISO capacity – being in some way crippled because it has been made clear by Sony that this speed applies to a ‘lockdown’ of focus and exposure with the first frame. This is not surprising as it’s a quiet, mirror-up mode using the off-sensor live view to maintain contact.

Crop or cram? Pixel density versus the big view…

Posted on By

The Alpha 900 offers an unrivalled view through its 100% prism finder. The extra brightness, as well as the size and clarity, make most subjects far easier to photograph well. For some users, however, the full frame camera brings a disadvantage in terms of reach and resolution. You need lenses 50% longer (and thus twice the size, and four times the cost!) to fill the frame with the same distant sports and wildlife subjects. I don’t need to remind anyone how popular these two subjects are with amateurs, and sometimes, how important to professionals.

New skins versus old wine – A350 or A380?

Posted on By

As the generation of Alpha 200, 300 and 350 reaches early retirement age it may be the time to grab bargains. The new Alpha 230, 330 and 380 have plenty of bonus points to win over new users despite the critical lack of video capture. But the older generation has some very tangible benefits.
The most obvious changes in the ‘Plus-30’ range are the use of a new smaller battery (NP-F50AM) shared with Cyber Shot consumer models, a dual MS ProHG Duo and SD card interface, substantial reduction in weight and size, improved rear LCD screen with auto brightness adjustment (only on the A330 and A380), and a radical overhaul of the graphical user interface to include sample picture tips (pioneered by Nikon).

Alpha 330 – future model?

Posted on By

Latest update May 7th:
Sony Style pages are starting to show this header picture, which shows three new models all sharing an unusual handgrip design and using the new lenses:
lifestyle_dslr_byseries
Note – the new models have handgrip sensors or appear to – maybe the nickel problem has been conquered. Also note the radical shift in position of the front control wheel and shutter release. The A380 is next to the A900, followed by the A330, and then the A230 at the end. All are smaller than the current A200-300 series. The A330 and A380 have what look like Live-View switches next to the prism, the A230 does not. This indicates that the viewing method has not changed, and we will almost certainly not get off-sensor live view or video. This does not rule out some kind of improved 720p LV of the focus screen, combined with electronically switched markings that could be turned off for recording video ‘off the groundglass’.

Tilt-shift with full frame DSLRs

Posted on By

After just a short while working with full frame, high resolution DSLRs the need for tilt lenses has really come home to me. Most lenses deliver their best results at fairly wide apertures like f8, it’s easy for detail to begin to look soft and lacking impact if you are forced to stop down to f22 to get everything sharp. Tilt adaptors and tilt lenses solve the problem. This article is repeated here after originally appearing on dPhotoexpert (and similar instrument images, in my first D3X test report for the British Journal).

Expodisc white balance with the KM Dynax 5D

Posted on By

The custom white balance function on the Konica Minolta Dynax 5D could not be quicker to use; turn the left hand top dial to the custom symbol, press the button in the centre of the dial, press the shutter after aiming the camera at your white or grey target. Custom WB is now set until changed with a new reading, or returned to fixed or Auto WB.
