Sigma has finally announced the DP1 digital camera. The special thing about this digital camera is that it offers dSLR-like CMOS sensor. The 7-12x larger sensor should help to get better quality but the lens of this camera is obviously not as good as a dSLR lens.
The size of the image sensor used in the DP1 camera is 20.7mm x 13.8mm. It is approximately seven to twelve times larger than the 1/1.8inch to 1/2.5inch image sensors used in ordinary compact digital cameras. The pixel size of the image sensor is 7.8μm. The large photodiodes deployed at a large pixel pitch capture pure, rich light efficiently and give the DP1 its high resolution and richly-graduated tones.
The camera measures 4.5" x 2.3" x 2", weighs 8.5-ounces and has a 2.5" LCD display. The Sigma DP1 will be available this Spring.
