2 questions here if you would be so kind. Thing is I really am smitten with the Leica X1 and there is a shop here in the UK that has them in stock so I could get one next week but I still have reservations about the fixed focal length. Does anyone find it a problem and/or wished that it was interchangeable? The E-P2 would be better for this as I would use the 20mm Panny lens but would have the option to swap the lens for a zoom or whatever. Also I have a spare 8GB SD card and was wondering if that would fill up pretty quick on an afternoons shooting. I know it all depends on how many shots I take etc but i would be shooting RAW and highest quality Jpeg also so it may fill up pretty quick. Any idea how many shots i would get on an 8Gig card at the highest quality for both Jpg and Raw? Thanks in advance.
