Just found (it wasn't easy!) a new Hexar RF from "Tri-State" in N.Y. It should arrive today. I'm looking forward to playing with it! I'm also now starting to look for a collection of LTM Russian glass as a simple addition.
I've also been spending WAY too much time researching the "M-Mount incompatibility" issues, and am still confused as to whether or not there's a problem. I'll probably borrow a Nokton and a ruler and just see for myself where the lens focuses. THAT should be pretty telling, unless I can find the 75 1.4...
This, for me, is a sort of sellers remorse- I traded my G2 and lenses for a Mamiya 7, and though I like the 7, I did enjoy the automation of the G (though occasional focusing trouble colored my experience with it, sadly) and the 135 negatives/slides were astounding in sharpness and clarity. I hope I get the same optical results (or similar) with the Hexar 50mm.
