Sigma has announced the new DP1s, an improved version of the DP1 digital camera. The DP1s still features the 14 megapixel Foveon X3 direct image sensor. New updates include the QS (Quick Set) function to the digital zoom button, found on the DP2 and SD14, that allows for faster and more convenient operation and improved performance when shooting backlit subjects.
