Sigma SD1 keeps Foveon X3 sensor, 11-point AF
Japan's Sigma Corp. has today taken the covers off its flagship Sigma SD1 15.4 megapixel DSLR at Photokina. It adopts a lightweight, weather-proof, solid magnesium alloy body to house its 1.5X crop Foveon X3 sensor. The technology enables the camera to capture all primary RGB colors at each pixel location rather than use a Bayer filter and leads Sigma to make a questionable claim to a 46-megapixel sensor.
An 11 point twin cross autofocus system guides the shots, while a three-inch LCD provides previews. Primary storage comes through CompactFlash cards. The camera is expected to be available February 2011, with pricing to be confirmed closer to the actual ship date. [via Photography Bay]
