Thanks to Stephen & Tom for opening this fascinating Thread! Thirty-five years ago, I was a working PJ and wanted an M2. A prominent Tel Aviv used dealer had none, yet luck was with me. A guy walked in to the shop wanting to sell one, and he did NOT like the deal offered. Sensing my interest, he was waiting for me when I exited the store.
I bought the M2 for around $330- in 1972, and it has been a "love affair" ever since. It's a 1965 model, with the little lever for Rewind. There are body rubs near the strap lugs and dings here and there. Like Tom, I'm left-eye dominant, however I'm blessed, in that I don't wear glasses for distance.
Tom highlighted the feel of pressing the M2's mechanical release button. I know of no other mechanical camera with this feel. The spring action is just right, and one learns at what point the shutter will release.
Talk about a rugged camera!... For sure, I rammed the thumb wind "home" 10,000 times and more. Tho' I love my Bessa R, when I wind & cock, I think about it and take it easy. When I quit PJ for health reasons, I had the M2 CLA'd at the best local repair shop in Tel Aviv at the time, the Elafant brothers.
The Summaron 35/2.8 that came with the M2 has been repaired twice... once in the UK for looseness in the mount, and once in Tel Aviv for grease stuck in the focusing collar. Having used Tri-x [and now Tmax] for most of my "photographic life," I can guestimate exposure with the M2+35/2.8 combination fairly accurately.
Again, I want to appreciate the classic camera legacy aspects of our Forum, and the substantial contributions of Stephen, Tom and others.
Cheers...
