Hey y'all. I recently purchased a 35mm Summaron 3.5 LTM. It has a couple of issues. The first is that the focusing knob gets caught on the frame lever of my m4, so I can't focus past that point without unmounting the lens and readjusting the focusing lever. This point is kind of moot because the second issue is that it only focuses to about 6 feet anyway. The focus ring in the lens that engages with the rangefinder on the camera seems to be too short to maintain contact with the focusing mechanism. Any of you hear of this and have any suggestions? The only thing I can think of on my end is that I'm using an off-brand ltm to M adapter. I'd like to solve these issues because this lens has immaculate glass and the first roll that I've shot looks amazing. Throughout all the research I've done online I've found very little answers to this particular problems(s). Most answers seem to focus on the lens being a "goggled" version. Unless Leica made a screw mount version of a goggled 35mm I'm pretty sure this isn't the issue.
