Sigma 18-125mm f/3.8-5.6 DC OS HSM
Kit lens owners seeking added stability without external support will welcome the launch of an image-stabilized 'walk round' lens from Sigma. The 18-125mm f/3.8-5.6 DC OS HSM combines a useful focal length range with a hypersonic focusing motor and optical stabilization in a remarkably compact package.

Sigma 70-300mm f/4-5.6 HSM for Nikon
Sigma offers Nikon D40 and D60 DSLR owners more reach for less outlay with the launch of two tele zooms with built-in focus motors. The popular 70-300mm f/4-5.6 DG Macro lenses in both standard and APO flavors have been motorized for owners of Nikon's D40 and D60 which lack support for tradition screw focusing.

APO 70-200mm F2.8 II EX DG MACRO for Pentax and Sony
APO 50-150mm F2.8 II EX DC HSM for Pentax and Sony
Sigma has announced the launch of 70-200mm and 50-150mm constant f/2.8 lenses for Pentax and Sony owners wanting lovely bright, sensibly-priced telephoto zooms. Both are part of Sigma's premium EX range and include hypersonic focusing motors and apochromatic design.

APO 120-400mm F4.5-5.6 DG OS HSM
Sigma has announced an optically stabilized 120-400mm f/4.5-5.6 lens. The lens will be available for owners of Sigma, Canon, Nikon, Pentax and Sony DSLRs. A maximum magnification of 1:4.2 also makes it useful for users who want to get a little closer. The DG designation means the lens will work equally happily on 35mm or APS format SLRs.

10-20mm F4-5.6 EX DC HSM for Four Thirds

Four Thirds users far and wide will appreciate the wide angle and telephoto zooms today announced by Sigma. The company's popular 10-20mm F4-5.6 and 70-200 F2.8 lenses have been converted to fit Leica, Panasonic and Olympus DSLRs. Both lenses include Sigma's HSM hypersonic focusing motors.

Sigma 200-500 f/2.8 EX DG
As part of Sigma's bumper lens launch, it has announced what might be the ultimate wildlife lens. Sigma claims the APO 200-500 f.2.8 is the world's first lens to offer an f/2.8 aperture at 500mm focal length. It comes with an "attachment" to give users a handy 400-1000mm f/5.6 option. The lens (which is cosmetically reminiscent of a piece of military hardware) weighs nearly 16kg and uses a dedicated Li-ion battery to provide power for focusing and zooming. It will be available in Sigma, Canon and Nikon mounts.
