I switched from the G2 system to Leica M's, and sold my G2 to someone much younger than I. He appears to be quite happy with it. It has a lot of nice features not commonly found on RF cameras, plus outstanding Zeiss lenses. My gripes:
- viewfinder quite small, especially for older eyes.
- poor autofocus -- operates on straight lines only.
- manual focus with knob on front and tiny display in viewfinder. Doesn't work well for me.
- flimsy shutter. If you're a klutz, chances are you'll poke a finger through it sometime (as I did) -- a $350 repair job.
I eventually supplemented my Ms with a Leica CM Zoom (now discontinued, I understand). Very solid and well-built. For the autowind, autofocus tasks, I like it better than the G2.
BTW, please let me know if you're selling Hassy equipment.
