I couldn't find anything addressing this in the forum, but I can't believe that it's only in my camera, so here goes: I have an MP (old ISO selector dial) that I bought as a "demo" about 2.5 years ago. It has been everything that I hoped it would be as far as feel and ease of usage. (I've been using an M6 for about 10 years and M cameras for 25.) Then, about six months after I got it, I got back a roll of film with vertical and horizontal light streaks on each frame. The verticals were not in the same place on each frame so some frames had one and some had two. The horizontal one was across the full frame about 1/3 up from the bottom. When I looked at the negatives, they extended only to the edge of the picture area, not into the sprocket hole area. Not quite believing it, I shot another roll and it was perfect - no light leaks. I called my favorite, nationally known repair person who suggested that I send it in. I did so and it was returned with new "light shields." It worked perfectly again - for six months, or about 25 rolls of film. This time when it happened again I had shot two rolls together. The second roll was perfect. I called my repair person and was told to send it back. More "light shields" were installed (at a very fair price). It worked perfectly again - for six months or about 25 rolls of film. This time, I decided to keep using it - since there seems to be no way of ever knowing if it is repaired at this point. Three rolls later it's still operating perfectly. I love the camera, but it's a bit frustrating not being able to use it for an important event or take it on a "once in a lifetime" trip. I'd be happy to send it to Leica, but I'm not certain that, even then, I could be certain it was fixed. Has anyone else seen anything like this and, most importantly, have you been able to get it fixed. Thanks.
