I want a pocket camera (maybe a big coat pocket

,) for the many days that I don't want to lug the 1D MkII and the heavy glass around. The S3 is just about the largest I would consider. However, the Panasonic FZ50 has some additional features I consider important, such as RAW shooting, a zoom ring and, if I remember correctly, real manual focus with a ring on the lens, as well. It is only slightly larger than the S3.
Has anybody here compared the two cameras? What was Canon thinking when they eliminated RAW from the S3? And optical viewfinders seem to have disappeared from their smaller cameras, along with the 3rd point (your forehead) that I depend on for greater stability of the camera, IS or not.
