The extremely popular Fuji X100 is currently in stock at B&H Photo as I write this. The X100 has proven itself to me as one of my most useful cameras— ever. It is the compact camera whose feature set Leica should consider for both the Leica M9 and X1, at a friendlier price than the Leica X1 (not that I’d be averse to a Leica X1, see my review of the Leica X1).
I recommend a 49mm filter for the Fuji X100, in conjunction with the lens hood— forget about the lens cap; the hood + filter both shades and protects the lens, and it’s always ready to shoot without that fiddly hood.
