Wonder if this thread will go on for at least 7 pages or more.

Personally I own 1 VC lens a 50mm f1.5 ltm w an M adapter, one Zeiss 21mm f2.8 and I enjoy them as much as my fathers LTM lenses and the 1970s M mount Leitzs. Yes one can see a difference, but a simple clean M2 with a 35mm elmar makes a winning combination.
