I only shoot digital, DSLR and rangefinder. I can appreciate the lure of the Nikon: I have a D2x, used mine today for the first time since November, because I needed telephoto and zoom-framing, and I admit that the feel was very good. Nikons are right there with Leicas on ergonomics. But these cameras are beasts. Without checking, I'd say a D2x with a typical zoom and a RRS right-angle bracket is heavier than most 4x5 LF cameras, and just about *any* 35mm film camera -- and it's lighter than a Canon 1DSII. And it really slammed home to me how much frontal area they have, and how people *look* at you when you're using one. (I was shooting in a waterfront park.) I can put my R-D1 and seven lenses in a briefcase...
I can't wait for the digital M. The R-D1 is good, but I can't wait for the M to arrive.
