Recently I've been shooting often in cool environments (0-5°C), often going back to a warm room inside. I'm shooting my new 35mm Biogon a lot on my M2 that had a reasonably cheap CLA. My tabbed 50 Summicron was mostly spending it's time in my camera bag.
While shooting last week, when I got my mint Summicron out of the bag, I noticed the aperture ring was stuck. With a little bit of force I could move the aperture rings again, and it kept on turning nicely. A few hours later I would try again, and it would be stuck again. The advance lever of the M2 made a slightly screetching noise, mostly when film was advanced and I would open the lever, ready to click and advance film.
The equipment spent half a week on ambient temperature now. Stuck aperture ring happens less often and the screetching is gone. What's going on, should I worry?
