Somewhat oddly, it has been a pretty good CES for fixed-lens compacts. Yesterday, Fujifilm announced their new X100S digital rangefinder, and now Sigma has an update to their DP line with the DP3.Like the previous DP cameras, the DP3 lens doesn't zoom, rather it's a fixed 50mm F/2.8. Because the sensor is still an APS-C sized Foveon X3, that gives it a full-frame equivalent focal range of roughly 75mm.
