15.4 megapixel Foveon x3 CMOS sensor; 28mm lens; 640x480 video with mono sound; Lithium-ion battery
Sigma's DP1 was one of the first large-sensor compact cameras to hit the market, about a year ahead of the start of the mirrorless craze. The DP1m and DP2m finally exchange that initial 4.7 megapixel Foveon sensor, which had been used in the DP1, DP1s, DP1x, DP2, DP2s, and DP2x, with a much higher resolution 15.4 megapixel sensor. The Foveon sensor works differently than a normal Bayer, using three different color layers to form an image that has the correct tones at every single pixel. The resulting image has the pixel dimensions of a 15.4 megapixel sensor but includes much more detail. Sigma is quick to call this 41 megapixels for marketing purposes, but the effective count in Bayer terms is probably a bit lower. As to the differences between the cameras: the DP1m has a 28mm lens, the DP2m has a 45mm lens. Past models have been slammed for slow operation and autofocus, relatively poor noise control, outdated video, and fiddly controls. Reviews note these same issues on the DP1m, but the new sensor's image quality absolutely astounds.
