Tamron’s 18-250mm lens – later adopted by Sony – was so good that it really takes some effort to beat it. Sigma has put that effort in, but the cost is a very much larger and heavier lens. If all you got was some better performance, it might not be all that exciting. But you get potentially superior anti-shake through its built-in OS, and faster focusing with HSM, the Sigma equivalent of SSM.

My Sony Alpha 380 was supposed to arrive before July 13th according to SimplyElectronics.net – via Amazon – claiming UK despatch of 2-10 days delivery after debiting my card on July 6th from a July 3rd order. Well, it didn’t arrive by July 21st, and after some email exchanges I have apparently obtained a refund for the charge they made for an item they did not have (though this was still showing as ‘processing’ in August). Warehouseexpress.com had got the A380 plus 18-55mm kits  by that time, for £10 less, and delivered in 24 hours. Update August 9th: under a month later, the warehouseexpress kit price has fallen by 10% (£50) to £548 inc VAT.

SIGMA redesigned their 70-200mm not long ago to change the EX version to DG, introducing new coatings which greatly improved microcontrast and eliminated digital camera sensor reflections. In 2008, this was further upgraded to the Macro II model with HSM sonic motor focusing, a new optical design capable of focusing down to 1 metre distance. In 2009 this became available, along with matched HSM-compatible 2X and 1.4X converters, for the Sony Alpha mount.

It’s the very last word in HD picture quality, smart shooting features and stunning looks. The new flagship of Sony’s HD camcorder line-up, the Handycam® HDR-CX520VE/505VE is packed with latest innovations to help you capture better-looking video and still images, whatever you’re doing. Press release from Sony, July 7th 2009.

PENTAX UK is pleased to announce the launch of the PENTAX K-7 lens-interchangeable digital SLR camera. The K-7 combines a variety of advanced functions and user-friendly features to ensure outstanding reliability and capability within a compact, lightweight body (says the press release from Pentax in the UK).

The K-7 joins the current PENTAX K digital SLR camera series as a high-end model in the range. True to its series concept, it has been designed to deliver outstanding image quality combined with ease of use, to benefit photo enthusiasts of all levels, including advanced amateurs. The K-7 also includes revised and upgraded features including viewfinder, shutter unit, continuous-shooting capacity, and exposure and autofocus systems.

Protected by a durable, high-quality metallic body, the K-7 is extremely compact and functional — as with all other K-series models — delivering enhanced portability and manoeuverability. The model includes several new user-friendly features, including video recording, high dynamic range (HDR), and automatic horizon correction. All of these features serve to deliver a highly effective photographic tool, perfect for all discerning digital SLR photographers.

The new Alpha 230, 330 and 380 models are radical ergonomic redesigns of the existing 200, 300 and 350 series. There is a 15% reduction in size (volumetric) and weight, an update to the styling, and a completely revised user interface with graphic representation of setting adjustments – with a built-in ‘handbook’ to accompany the modes and options. They also have mini-HDMI image output, compatible with Bravia TVs and with interactive software inside the camera to allow the Bravia’s own remote control to change, orient and zoom into images (Bravia Sync). Twin card storage is MS ProHG Duo/SD and only one card is usable at a time, with a hardware switch to change slots. A smaller battery type (shared with the HX1 Cyber Shot) is used. A new self-timer drive mode grabs a quick burst of 3 or 5 frames, cutting the chances of spoiled portraits and groups shots when someone blinks at the wrong moment.

The new flashgun HVL-F20AM operates as a wireless flash controller for the full-frame α900. “While Sony’s flagship DSLR does not have its own integrated flash, the HVL-F20AM can be used as an inexpensive trigger for wireless remote flash heads” according to Sony UK.

There is no need to dismantle the mount of the original series Sigma AF TELE 400mm f/5.6 lens, to bring non-functional versions (old chip) up to speed with later film and current digital SLRs. The whole process takes under five minutes, and requires two tools – a small Philips screwdriver, and a precision end cutter.

This is not a step by step, since the instructions for this operation are very clear and the procedure is simple and nearly foolproof. It is simply a reassurance for those worried about changing their screen, with some tips.

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).

Sony’s new back-illuminated CMOS sensor design makes its first appearance – along with technology borrowed from the Alpha system – in a new HD Handycam video model, the HDR-XR520VE/500VE. Hopefully presaging future DSLR developments, the range also includes models with built-in GPS tracking to record the location of shots as you film.
