Just wanted to quickly say that for the last two weeks I have been using my Mamiya 7II in temperatures hovering around -8 – -20 degrees celsius and it has performed absolutely flawlessly. I've never put it in my bag to keep it warm and several times the camera was actually so cold I couldn't touch it with bare hands. I had thought about selling my kit a while back but am glad I didn't – I tried shooting with my Technika in these conditions and it was nearly impossible.
Anyway, just wanted to put in a little plug for this great camera. T
