The flare occurs with strong side lights and does not affect a 1.7 mm strip at the lower border of the negative in the camera (which is at the top of the image when seen correctly). The flare is strongest close to this unaffected strip and is visible throughout the rest of the image. The thoughts I have about this is that the deeper rim of the shutter housing seen from the back of the camera is shielding the lower strip from flare. This suggest that the rays come from the bottom of the inside of the leica camera in which the plastic plug is pushed. Testing with a strong flashlight reveiled no leakage from outside, so it must be reflection from the black painted bottom itself from light coming through the lens. I noticed that the M4-P has no light baffle immedeately behind the lens mount, while the M6 has such a baffle. So, there are three questions I like to pose to the Leica Group: 1) Has anybody seen the same kind of flare (with the 1.7 mm strip) 2) If so, in what camera and with what lens and what is your explanation 3) Did Leica put this baffle in the M6 to avoid the flare I see in my M4-P or does it have a function in the light meter system of the M6. Thanks very much indeed for any input on this topic, Bert Otten
