Sigma 10 - 20 mm DC lens
Pre-PMA 2005: The second of three DC (digital SLR only) lenses announced by Sigma today is the 10 - 20 mm F4.0 - F5.6 EX DC HSM, an interesting super wide-angle lens which would provide 15 - 30 mm equiv. on a 1.5 FOV crop camera (such as the Nikon D70). This lens also features Sigma's HSM (HyperSonic Motor) for high speed silent focusing with manual focus override.

Sigma Corporation is pleased to announce the launch of the new 10-20mm F4-5.6 EX DC HSM lens.
10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras.
Wide angle of view (102.4°at 10mm and 63.8°at 20mm) offers the photographer greater freedom of expression. Three SLD glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
