I picked up a very worn Super-Takumar 200mm f4 (for pocket change) on which the glass looks good but the barrel seems to need tightening somewhere inside. The barrel moves up and down a millimeter or so relative to the mount, and also moves in and out a millimeter or so, again relative to the mount.
I see three tiny screws on the focusing ring, and three more on the depth-of-field ring. I have a screwdriver for that size of screw. If I remove the three screws on the focusing ring, and then (I guess?) slide the focusing ring off, will I find more screws, either the ones that need tightening, or ones that, once removed, lead further to the ones that need tightening? BTW, the depth-of-field ring is loose, and spins all the way around the lens freely. I suppose if I got the focusing ring off, then slid the depth-of-field ring off, I'd see what needs to be done to secure it in place? Are there any FAQs, web sites, etc. that may help me get through this? Any other suggestions? I've never taken apart any lens before. Also: Maybe I should ask this in another thread, but -- why does the front section screw off? Were there interchangable front sections or something? Many Thanks, Greg
