What Thomas said. That said, if someone forced me at gunpoint to say, I'd have to either go with the F or the F2AS. F3 looks cool, but it's just as loud as an F2, and it has that annoying meter readout in manual mode where you're either overexposing, properly exposing, or underexposing. No idea as to how far off you are. The F4 with the stock DP-20 finder is a BIG improvement over the F3.
