Hallo there, I have reached the point where I am contemplating buying a Leica camera. I like manual cameras, precision and a quality lens. Living in a city I find my nikon fm3a (an excellent camera) to be too visible and a little heavy in the hands for certain photographic moments. And so, not having the cash to purchase a modern Leica new and after considering the Bessa T etc., I am looking at the Leica M2, the Leica M3 and the Leica M6. What do people recommend? And why? is there a hugh difference between, say the Leica M3 and the M6? I know these questions are a little broad but I am grateful for any suggestions. Thanks a lot. M.
