Just posted! Our new lens review of Canon's top-end fast telezoom, the EF 70-200mm F2.8 L IS USM. This is Part Two in our planned tetralogy of reviews featuring 70-200mm F2.8 lenses tested on both APS-C and 35mm full frame cameras (coming soon! 'The Tamron Menace' and 'Revenge of the Sigma'). In our last review we found the Nikon 70-200mm F2.8 VR performing superbly on DX but struggling on the 35mm full-frame FX format, so how does Canon's equivalent stand up to our exacting tests?

We've just posted a gallery of samples from the new Olympus E-420 digital SLR, including a selection taken with the new Zuiko 25mm F2.8 'pancake' lens. The E-420 updates the 'world's smallest SLR' (the E-410), whilst the new lens offers an equally compact alternative to the more common 14-42mm zoom kit lens. (11:35 GMT)

Adobe is submitting its DNG 'universal RAW' format to the International Standard's Organization (ISO), in a move aimed at increasing acceptance and usage. The format is being proposed as part of ISO's TIFF/EP (electronic photography), standard. We spoke to Adobe about the move. (16:20 GMT)

As well as adding motors to its existing lenses, Tamron has also started building motors into its new Nikon-compatible lenses. The 28-300mm f/3.5-6.3 VC lens offers a 10.7x zoom range with the company's proprietary optical stabilization system. DX-format users get fields of view equivalent to 43-465mm (in FX terms). (11:10 GMT)

Tamron has continued its process of adding in-lens motors to its Nikon-mount lenses, with its 28-75mm f/2.8 being the latest recipient. This makes the lens fully compatible with the Nikon D40, D40x and D60, offering their owners fields of view equivalent to a 42-112.5mm lens (in FX/35mm terms). The magnificently named 'SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) MACRO' can focus as close as 33cm throughout its zoom range. (08:10 GMT)

Olympus has launched a consumer-level wide angle lens for the Four Thirds system: the Zuiko Digital 9-18mm f/4-5.6. The lens, that offers fields of view equivalent to 18 - 36mm in 35mm terms, makes extreme wide-angle zoom more accessible to users of the Olympus E-System, Panasonic DSLRs and selected Leica Digilux cameras. (05:00 GMT)

Olympus has launched the E-520, an update of its E-510 DSLR. The E-520 represents continuity, rather than revolution within the E-System camp. This process of orderly transistion sees the arrival of contrast detection AF at the E-5XX level of camera. This feature does not represent all the camera's new talents, however, with a larger LCD and Face Detection doing their utmost to add buyer appeal. (05:00 GMT)

Adobe has delayed an update that will add support for Flickr users to its Photoshop Express online image editing and storage service. The service, currently at the Beta stage, allows images to be stored or pulled from the users' other websites and edited without over-writing the original. The latest update, which also adds a 'Save As...' feature and the ability to embed slideshows in other websites, has been postponed to allow bugs found late in the development process to be fixed. (09:55 GMT)

FujiFilm has released a firmware update for its F100fd compact camera. The update is a response the 'pink banding' issue that has been the subject of heated discussion on the FujiFilm Talk forum. FujiFilm says the modification will "reduce" the pinkish colored banding reported by some users. (12:20 GMT)

Just posted! Our new lens review of Nikon's top-end fast telezoom, the AF-S VR-Nikkor 70-200mm F2.8G ED-IF. This is the first in a series of reviews in which we'll be comparing it with similar lenses from Canon, Sigma and Tamron, using both APS-C and 35mm full frame cameras. The 70-200mm F2.8 VR has long been a favourite of Nikon DX format shooters, but how well does it stand up on the new full-frame D3? Read on to find out. (16:50 GMT)

Canon has released firmware updates for its range-topping EOS 1D Mark III and 1Ds Mark III cameras. The updates, to versions 1.2.3 and 1.1.2 respectively, provide new custom functions to provide direct access to autofocus points and additional ways to apply exposure compensation. They also promise to: "improve the stability of AF accuracy in AI servo AF mode when shooting extremely low-contrast subjects." (15:40 GMT)

Just posted: Our review of the FujiFilm S100FS. The S100FS offers DSLR-like handling and control with the convenience of a single, built-in lens offering an outstanding range. It is also built around a comparatively large 2/3" sensor and utilizes FujiFilm's Super CCD technology. So do these features, along with film simulation modes that match the results to subject matter, offer a satisfying alternative to the money-pit that DSLR ownership can be? (09:30 GMT)

As a prelude to our full Canon EOS 450D / Digital Rebel XSi review we have just posted our hands-on preview of the 450D. This is the latest in line of the popular 'Digital Rebel series' of compact digital SLRs and features a twelve megapixel CMOS sensor with Live View and dust reduction. Other headline changes include a 3.0" LCD monitor, SD/SDHC storage, High ISO noise reduction and a range of other features handed down from the EOS 40D. Our 'hands-on preview' articles are essentially the first half of a review which will at least give you a taste for the design and operation of the camera, full review to follow within the next two weeks. (16:20 GMT)

Nikon has released a revised version of its recently withdrawn firmware update. The company has updated the 'B' firmware to V1.11, and has reissued the previously withdrawn V1.10 'A' firmware. Link to Nikon UK download page and a PDF detailing the new features now included. (12:40 GMT)

Just posted! Our concise review of the Panasonic Lumix DMC-TZ5. The successor of the popular TZ3 is the latest addition to Panasonic's family of compact long zoom cameras. It comes with the same versatile 28-280mm equiv. 10x zoom lens as its predecessor but now offers a slightly higher resolution, an improved LCD and High Definition video capture. Nice new features indeed but has Panasonic also managed to sort out some of the image quality issues that we found on previous TZ generations? Find out after the link... (14:15 GMT)
