I have used a lot of cameras, but my F1n sans motor was smother more satisfying and i think lighter than the fabled Leica M3. (Yes I've used the Nikon F2... too many quirks compared to the modern F-1 and match needle meter)

That is all. Use what you wish. My favorite photographer from grad school did outstanding work with a Pentax K1000 and 50mm f2.
