Sigma DP2 Digital Camera

The new Sigma DP2 compact digital camera features a 14 megapixel FOVEON X3 direct image sensor (2,652 × 1,768 × 3 layers). At 20.7 x 13.8mm, the DP2's 14-megapixel image sensor is SLR-sized. This is about 12 times larger than the 1- to 2.5-inch sensor, and 7 times larger than a 1- to 1.8-inch sensor used in a conventional digital compact. This generous size takes the DP2's image quality to a different dimension. Picture this. Light traveling through a small lens is captured by a small sensor and turned into an image. Light travelling through a large lens is captured by a large sensor and turned into an image. What’s the difference between these two images? Essentially, it's a difference in quality. In the case of the small image sensor, the image is magnified by a high ratio when it's printed or displayed on a computer screen. This makes it tricky to reproduce the dynamism and 3-D feel of the subject. The DP2 does just that by using a large integral image sensor. Building on this success of the DP-1, the D
