Leica M2 repair & common faults
Excellent coverageThe Leica M2 is a fully mechanical rangefinder from the late 1950s, built without a meter and without any battery in the circuit at all. Its faults trace almost entirely to two things ageing over sixty-plus years: the rubberised cloth shutter curtains and the rangefinder's internal optics.

Common Leica M2 faults
Leica M2 rangefinder patch is dim or hard to see
A faint, ghosted or vanishing central patch usually means the internal beamsplitter's silvering has thinned or the small prism surfaces have hazed with age, both very common on a camera this old. It's an optical fault inside the housing, not a focus adjustment. Worth wiping the small front rangefinder window first in case it's simply dirty.
Leica M2 shutter curtains show pinholes or light leaks
Tiny bright specks or streaks on developed film point to the rubberised cloth curtains cracking or thinning after decades of light exposure, a well known fate for this generation of Leica shutter. It's a material fault in the curtains themselves rather than a timing issue. Holding the shutter open on B towards a bright window can reveal pinpricks before you shoot a roll.
Leica M2 slow shutter speeds sound sluggish or run long
Old lubricant in the slow speed escapement thickens over time, so speeds below around a fifteenth drag, hang or land noticeably slower than marked. It's a mechanical timing fault in the delay train rather than anything electrical, since the M2 has no electronics to blame. Faster speeds and the general feel of the camera are often unaffected.
Leica M2 frame counter doesn't advance or won't reset
A counter that skips frames, sticks, or fails to zero when the back is opened usually means wear or a sticking pin in the small geared counter mechanism, separate from the film transport itself. It's a minor, contained fault rather than a sign of wider transport trouble. Confirm it actually resets when you open the baseplate to load film.
Leica M2 wind lever feels stiff or won't complete a stroke
Binding on the wind stroke usually comes from hardened old grease in the advance gear train or, less often, the shutter cocking linkage catching partway through. It's a lubrication and wear fault rather than film jamming in most cases. Check the rewind knob isn't left engaged, since that alone will lock the lever solid.
