I have a 35mm lens for my Canon IID and the lens focusing is stiff to frozen. Any idea of the best place to get it CLA'd? I was thinking about putting a drop or two of clock oil in there to free it up and then find a good grease for a more long term solution, anyone here have any experience doing this kind of thing? Would that be a mistake? Also, the viewfinder has a distance range knob on it, but it doesn't seem to do anything. Can I just use the one built in and just use the viewfinder to compose (is this how it is supposed to be?) I'm new to the rangefinder world and am finding it a little weird--not in a bad way, just different. The main issue I am having is that I am so used to seeing the image backwards from side to side that I keep moving the camera the wrong way! Anyway, I'd like to try out the 35mm lens but I need some advice first.
