PMA 2010: Sigma updates SLR, two compacts and intros five lenses

• Sigma has updated its sole SLR. The new model, the 14-megapixel SD15, continues to use the unique Foveon X3 direct image sensor, which has a unique design. But it has a larger, sharper (460,000 dots) 3-inch LCD, stores photos on SD memory cards, and has a more powerful processor that can fire off more photos in burst mode. Sigma claims you can shoot 21 RAW files in a stretch, although it also states that the capture rate is the same 3 frames-per-second as most other SLRs. The company also said it has made the graphical user interface easier to use.

• The company also unveiled two new advanced compacts the same 14-megapixel Foveon sensor as the SD15, improving the quality of photos the new DP1x and the DP2s should deliver in low-light. But unlike the new Micro Four-thirds types of compacts, neither can take interchangeable lenses. The DP1x has a wide, 28mm fixed focal length lens. The DP2s has a 41mm fixed lens. Like the SD-series SLRs and previous DP-series point-and-shoots, both have advanced features, such as the ability to capture RAW files as well as many manual settings, including manual focus.

• Sigma also debuted five SLR lenses, three of which include a new type of glass element (called FLD) that Sigma says will improve image quality. The three are an 8-16mm f/4.5-5.6 wide-angle lens, a 70-200mm f/2.8 telephoto zoom (with image stabilization) and a 17-50mm f/2.8 zoom (with image stabilization). The other two new lenses are 50-500mm f/4.5-6.3 zoom with image stabilization and a prime (non-zoom) lens, an 85mm f/1.4. All are available with mounts for most major SLR brands, including Canon, Nikon, Sony, and Four-thirds cameras, as well as Sigma's SD15.

Sigma didn't provide pricing or availability on any of these new products.
