PMA 2010: Continuing our way through Sigma's bag of goodies, we come to the widest-angle rectilinear lens yet made for APS-C DSLRs, in the shape of the 8-16mm F4.5-5.6 DC HSM. Essentially an equivalent of the company's 12-24mm lens for full-frame, this features a disorientatingly-wide angle of view of 121 degrees for exaggerated perspectives. It has a built-in petal shaped hood, HSM focusing with full-time manual override, and a minimum focus of 24cm. Again, it will be available to fit Canon, Nikon, Pentax, Sigma and Sony SLRs.
PMA 2010: Last but not least of the lenses, we come to Sigma's upgrade for its popular 50-500mm ultra-telephoto zoom which now incorporates Optical Stabilisation - a hugely welcome addition to such a long lens. Again Sigma claims the OS offers up to four stops benefit, and works with Sony and Pentax SLRs as well as Canon, Sigma and Nikon models, with the stabilized viewfinder image aiding in focusing and composition. The all-new optical design uses 22 elements in 16 groups, including four SLD glass elements, but the filter size has grown to a whopping 95mm.
PMA 2010: More than a year after first showcasing it at the 2008 Photokina trade show, Sigma has re-announced the SD15 digital SLR. Successor to the SD14, it incorporates a 14MP Foveon X3 sensor, the same True II processor as the latest DPx models, and a larger 3.0" 460k dot LCD. Other features include SD card compatibility, ISO 100-1600 (50-3200 extended) sensitivity, 21 shot raw buffer at 3fps and 5 frame auto bracketing for HDR-enthusiasts.
PMA 2010: Sigma has also taken the opportunity to reveal a bit more about its new 'FLD' glass, which is used in several of the company's lens designs simultaneously unveiled at PMA. Standing for 'F' Low Dispersion, the material is claimed to have performance equivalent to fluorite glass, but at a more affordable price. Its optical characteristics apparently allow excellent correction for residual chromatic aberration, while its lower density compared to traditional optical glass allows lighter lenses. It's used in the company's new 70-200mm, 17-50mm and 8-16mm designs.
Just posted! Our lens review of the Sigma 18-250mm F3.5-6.3 DC OS HSM. Sigma's latest superzoom is essentially an extension of the company's older 18-200mm design, but now sports both optical image stabilization and an in-lens hypersonic autofocus motor for users of Canon, Nikon, Pentax and Sony DSLRs. But in this popular segment of the market it faces stiff competition, not only from the camera manufacturers' own offerings but also from Tamron's superzoom designs. So how does it measure up?
Sigma has added its Optical Stabilization system to its popular 17-70mm fast standard zoom lens. The 17-70mm F2.8-4 DC Macro OS HSM will be available in Canon, Nikon, Sony, Pentax and Sigma mounts. The latest version offers a slightly wider aperture at the long end of the zoom though gains weight and length and has a slightly reduced maximum magnification ratio. Adding image stabilization to a lens that already combines a comparatively fast maximum aperture range is likely to make it an even more tempting replacement for the kit lenses supplied with most DSLRs.

These version also add support for Sony's recently launched A500 and A550 DSLRs. UK customers can obtain updates from the company's website. The updates should be available from US distributor Shortcut Software very soon.

Sigma has announced the DP1s digital compact camera, a slightly revised version of its DP1 large-sensor compact camera. Featuring the same sensor and processor as the DP1, it assigns the QS (Quick set) function from Sigma's DP2 to its digital zoom button and the ability to simultaneously shoot separate RAW and JPEG images. The company says it also performs better when shooting backlit subjects.
Just Posted! Our review of the Sigma DP2. Sigma was the first company brave enough to put a large sensor in a compact body and its DP1 was an interesting, if flawed creation. The DP2 is its second attempt - featuring a 41mm equivalent F2.8 lens and a series of improvements derived from the company's experiences with the DP1. However, it is no longer the only compact camera claiming to offer 'the power of DSLR' so can the DP2 see off the interlopers and does its unique sensor design give it hidden depths?
Sigma has announced an image-stabilized telephoto zoom in the shape of the 70-300mm F4-5.6 DG OS. Suitable for use on both APS-C and full frame cameras, this lens incorporates Sigma's Optical Stabilization technology allowing hand-held shooting at shutter speeds up to 4 stops slower than usual, along with a circular diaphragm for attractive rendition of out-of-focus backgrounds. The minimum focus distance is 1.5m giving a maximum magnification of 0.26x; unlike Sigma's non-stabilized 70-300mm zooms there's no extended macro focusing option. The lens will available for users of Sigma, Nikon, Canon, Pentax and Sony SLRs at a SRP of £399.
Sigma has released an update to its Photo Pro image-editing software. Version 3.5.2 for Windows and v3.3 for Mac claim to improve processing of highlight areas in RAW images and now offer the 'ProPhoto RGB' color space. Exposure warning is also displayed for RGB channels in the histogram in the Windows version.
Sigma has announced the price of the 10-20mm F3.5 EX DC HSM lens it announced in March 2009. The new lens, that will be sold in parallel to the older, variable aperture design, will cost £649.99. Sigma, Canon and Nikon versions will be available in July, with Pentax and Sony variants to follow in August.
Sigma UK has announced the price and availability of the DP2 digital compact camera. Announced at the Photokina 2008 exhibition, this 14MP camera (4.7 million pixel images with three pieces of color data recorded at each location) with a large FOVEON X3 sensor has started shipping in the UK at a suggested retail price of £599.99. The optional VF-21 Viewfinder and HA-21 Hood adapter are available for £114.99 and £19.99 respectively.
Just Posted! Our preview sample gallery from the Sigma DP2. We were lucky enough to be loaned a full production version of Sigma's latest camera on a recent trip to Japan for just long enough to put together a quick gallery of sample images. We used a variety of subjects and color modes, and ISOs from 100 to 800. Click through to get an idea of the image quality this new large sensor compact can deliver.
Just posted! Our latest lens review focusing on Sigma's 10-20mm F4-5.6 EX DC HSM ultra-wideangle zoom. A firm favourite with the more budget-conscious APS-C user since its introduction four years ago, this lens is now challenged by some new young pretenders intent on stealing its market share. So can this old warrior still fight off its challengers, or is age beginning to take its toll?
