Hmmm. I've always liked the Elmar and the results, especially with b&w. I'd love to have a IIIF with this lens, but since I'm unlikely to afford both an LTM and M body, an M is more flexible for me. So ...
Aside from having this lens with adapter, are any of the M mount Elmars of the exact same design? Or should I just get an LTM Elmar? And if so, what generation/version/SN range?
