Leica M Shooter
In my experience a freshly CLA'd "mint" Leica M feels and shoots tight and sometimes better than new - again, in my experience. When the MP first came out I bought one of the first .85 models; it had to go back to the factory because the shutter speeds were off (they essentially had to do a CLA on it).... any new M just feels tighter, fresher, unworn and new. ...
I don't recall when Leica adjusted the framelines, but the M4-P was the first with six framelines. Even so, Leica has said they adjusted the framelines (it seems to me it was in the middle of M4-P production) to be maximized by certain distances and had nothing to do with being paired.As far as I know are the framelines of the M4-2 and later (all the models after the M5) less precise than those of all the earlier M camera's. ... too many framelines in them. ...
Yes, that's stating the obvious. I suppose if you're making a life-long purchase, paying three times that of used really wouldn't matter that much in the long-term view - particularly if you're talking about a film M camera, which should outlast your grandchildren (the ability to buy and process film notwithstanding).... You could never have your M2 if someone else didn't buy it new.
