Hi there, I just purchased a Canon A1 as an upgrade to my FT QL. The camera seems to function perfectly well, with the exception of the AE Mode Selector Dial, which allows you to switch between Av and Tv AE modes. At first I thought the dial was stuck on Tv, however I then realised that it can be turned between the two choices but it's very stuck and requires a great deal of force to turn. Given that it's sawtoothed metal, this is very painful and it takes a long time to get the right angle/grip for it to turn. Is there any way I can lubricate the dial to make it easier to turn?
The dial in question is this one:
Also, is there any way I can know that my light seals are working well aside from running a roll through the camera?
Thanks!
