Pocket-lint came out with a review of the 14.6MP Sigma DP1 today. The camera uses Foveon X3 CMOS sensor technology, which is a sensor that can record 3 colors--red, green and blue--at each pixel location.
The sensors as described by the Sigma site use "three silicon embedded layers of photo sensors stacked to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. The size of image sensor used in DP1 camera is approximately 10 times larger than those used in an ordinary point and shoot digital camera."
The camera promises to take pictures as good as a dSLR camera. The incredible thing about this camera is the sensor is as big as that found in some lower-level dSLR cameras. It's 20.7x13.8mm!
The DP1 can also shoot in Raw format. The lens is a wide angle but with no zoom of 28mm (35mm equiv).
The camera also has a hot shoe for external flash units, shutter speeds of 1/4000sec. to 15sec, and the following manual shooting modes: Auto Mode, (P) Program AE, (S) Shutter Priority AE, (A) Aperture Priority AE, (M) Manual.
