I recently acquired a Pro1 and I've been doing some shooting in RAW. The jpg preview images seem extremely small in resolution and its hard to tell if my shots are in focus or not when I review them on the camera's LCD. The G6 that I had allowed the user to set the jpg preview image for RAW all the the way up to the max resolution. Is it possible to set this on the Pro1 or am I stuck with 640x480 preview images? I didn't see anything in the manual....
