Does anyone have any experience in retightening a worn focus lock lever on the GX680 II or III? I have both and while the II is really worn, the III is starting to get too sloppy as well.
I've open them up and tried what I could think of and it just looks to me like the brass block clamp that closes down on the focus knob axle was never meant for adjustment, only factory replacement.
Any advice would be very welcome.
