Developed a roll from my M3, had quiet a few photos shot at low speeds (1/15th-1/2 second) and noticed that on the right side of the image frame there is a thicker black area, maybe 2-2 and a half the normal frame spacing on the neg roll. Looks like the second curtain is dragging slightly at those slow speeds. Otherwise it works great, shutter speeds appear as close as I can gather and all exposures look good (it's also much smoother and feels nicer to use than my M4-P, and the shutter is a lot quieter too). The self timer also functions without hesitation.
Could this drag issue resolve itself after a few rolls of film? It is noticable, but it doesn;t interfere with the frame too much... is there any online documentation regarding tensioning the second shutter curtain? The RF and VF are also very clear, frame lines are brights and the RF patch is contrasty and easy to focus. This camera is MUCH nicer than my M4-P (tempting me to sell the M4-P and get an M2 for the 35mm frame lines... the M3 was purchased for use with a 90mm Elmarit-M for portraits).
I've just received my IIIc back from CLA after the slow shutterspeeds stopped working, and am about to send the M4-P out for RF re-alignment and flash socket repair so am not too keen on sending the M out for repair due to $$$.
I am happy continue to use the M3 and deal with the shutter issue until the M4-P is back and I have the funds to send it off for a CLA at a later date, but if there is a guide for adjusting shutter curtain tension I would be interesting in finding out more.
