What film do you use? I have a M6 TTL, which I bought nearly two years ago, but only started using this past autumn, as I had been working abroad.
And, if I am able to correctly identify the lenses, that is the Summicron 35mm and the Summicron 50 mm that you have posted; was the 35mm used or new?
I have a TTL also, the LHSA special edition, my main camera. The 35 cron asph I have had for quite some time, it was just sent off for service so it should be like new when it returns tomorrow. The v5 50 cron was lightly used and replaced a 90 cron, most people keep leica stuff in very good shape so no issue not buying new. I shoot trix and develop it in xtol with a jobo rotary processor 99% of the time.
