Sigma might be more commonly known for its camera lenses, but the company does come up with its own DSLR cameras too, and it has just unveiled its latest flagship camera, the SD1. Said camera sports a 15.3-megapixel Foveon image sensor. Foveon sensors differ from usual sensors by capturing red, green, and blue at each pixel site, instead of just one of the three colors. The camera itself sports a tough magnesium alloy chassis that boasts a dustproof and splashproof design, ensuring that you won’t have to treat it like it were made from glass. Other features of the SD1 include a 1.5 crop factor, CF memory card support, 11-point autofocus system, 3-inch 460,000 pixel display and a 98 percent coverage viewfinder. Pricing wasn’t mentioned, but it’s said to be in the region of Canon’s EOS 7D which currently will cost $1,500 for the body only and $1,700 with a 28-135mm kit lens.
