So I have decided to start using the Agfa Isolette I that my grandparents had down in their basement. Its a folding camera that takes medium format 120 film. It's in really great shape, except for one thing, the Focusing Ring is frozen between 8 and 10 feet. I am trying to decide if I want to take the whole lens apart and loosen up the the gunk that has caused it to freeze. I know what the problem is, its just I am not sure if I want to attempt to fix it and risk breaking the thing because of my stupidity. Also I wonder if I leave the camera this way and use it I am wondering if I might get some cool effects.
