After viewing Ken Rockwells test of a P&S compared to a 5DmII and a 17-40 F4 in disbelief, I thought I'd do a little test of my own. KR's test pictures look very similar in sharpness, contrast, etc. Mine don't. Nikon D70s with Sigma 18-50 F2.8 is the first, the second is with a Casio Exilim 6mp PS. Both with the same exact settings except for F stop (D70s at F3.3, Casio at F3.1) Need I say more?
