Hi, Here is my take on the LX problem:
1. It cannot be the lens because the peoplem occurs with various lenses. 2. It may be that the screen does not sit properly. Take it out, inspect it for damage, check the screen "bed" for dirt or other obstacles, then put the screen back in. 3. The rubber rest(s) underneath the mirror are not properly aligned or are beginning to desintegrate (is there only one rest or two? I forget). Lock the mirror up, inspect them. Apply slight pressure. How do they react? If they are beginning to get sticky, "sticky mirror" is around the corner. If they are not sticky, then they are not properly aligned. Bernd's procedure for testing the mirror alignment is a very good one, but one minor adjustment needs to be made --- do not set the lens to infinity (infinity is not always exactly there where it is marked). Instead, focus very well on a close object, then check if the image on the film plane is sharp. > - put the camera onto a tripod. > - glue a transparent tape ( TESA ) over the shutter window > - turn the lens to infinity. > - set the camera to "B", release and let the shutter stay open. > If the picture on this "screen" is OK, then the mirror is misaligned.
