Sigma launches stabilized 70-200mm F2.8 telezoom
PMA 2010: Sigma has launched into PMA with a veritable salvo of interesting new products. First up is the APO 70-200mm F2.8 EX DG OS HSM, an image-stabilised fast telezoom with ultrasonic-type silent focusing that provides a direct alternative to recent arrivals from Canon and Nikon. The all-new optical design uses two elements made of Sigma's newly-developed 'FLD' glass (plus three of SLD glass) to reduce aberrations, a 9-blade circular aperture for attractive bokeh, and features full-time manual focus override. The Optical Stabilisation system promises up to four stops benefit when hand-holding, and like other recent Sigma lenses, can be used by owners of Sony and Pentax cameras (the lens will also be available in Canon, Nikon and Sigma mounts). Last but not least, a dedicated adapter that extends the length of the hood for APS-C users is supplied as standard.

Sigma releases 85mm F1.4 EX DG HSM
PMA 2010: Sigma has announced the 85mm F1.4 EX DG HSM, a large-aperture short telephoto lens which is bound to pique the interest of budding portraitists. Featuring a hypersonic focus motor with full-time manual focus override, the lens uses a 9-blade diaphragm for attractive background blur, and has a minimum focus distance of 85cm. It comes with a lens hood adapter for ASP-C/DX users that extends the length of the hood to give more effective shading, and will be available in mounts for Canon, Nikon, Pentax, Sigma and Sony SLRs.

Sigma releases 17-50mm F2.8 EX DC OS HSM
PMA 2010: Third on Sigma's long list of introductions is an image-stabilized fast standard zoom for APS-C SLRs. The 17-50mm EX DC OS HSM offers a slightly wider angle of view than the company's previous models in this class, and alongside optical stabilization also adds a hypersonic autofocus motor for users of all mounts (Canon, Nikon, Pentax, Sigma and Sony). It uses two elements made from Sigma's new 'FLD glass', plus two glass mold and one hybrid aspherical elements, to reduce aberrations. The minimum focus distance is 28cm across the entire zoom range, giving a maximum magnification of 0.2x, and the 77mm filter thread does not rotate on focusing.

Sigma announces DP1x compact camera
PMA 2010: Sigma has announced the DP1x digital compact camera, a revised version of its DP1 large-sensor compact camera.

It also shares the revised rear design of the DP2s, with a dedicated 'QS' (Quick Set) button and more visible labeling of controls.

Sigma goes ultrawide with 8-16mm F4.5-5.6 DC
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.

Sigma stabilizes 50-500mm ultra-telezoom
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.

Sigma re-introduces SD15 digital SLR
PMA 2010: More than a year after first showcasing it at the 2008 Photokina trade show, Sigma has re-announced the SD15 digital SLR.

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.

Sigma adopts 'FLD' glass
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.

Sigma 18-250mm DC OS HSM review
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 stabilizes 17-70mm fast normal zoom
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.

Just posted: our in-depth Sigma DP2 review
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?

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 lens will available for users of Sigma, Nikon, Canon, Pentax and Sony SLRs at a SRP of £399.
