I'm looking for a light, pocketable P&S to fit on my Zeiss 80mm Diascope when birding. I'd prefer something that won't vignette (that probably limits it to a 3x zoom), has a large LCD (preferably 3" or 2.5" with swivel), remote or cable control, short shutter lag, and RAW capable (not the highest priority if the compression isn't too obvious). Any suggestions?
