KoNickon

FM2n, without question. I think it's one of Nikon's best-ever designs, and seems indestructible. The F3 is heavier, with much slower flash synch (not to mention an unfortunate flash mount location), and the metering is quirkier. I'm also not convinced about its sturdiness. And one more thing -- to turn on the F3 you have to throw a rather stiff and not at all ergonomic switch. Really not well done at all. With the FM2n (as with earlier Nikons like the F2 and the Nikkormats), just pull the wind lever to its standoff position.
