I added a freshly purchased B&W 49m 007 Clear MRC Nano filter to my Q for my recent trip and used it constantly in the sometimes dirty environment. Now I'm seeing unwanted reflections of objects in images taken at night in artificial light. I wouldn't have believed this was going to happen. My apologies to another forum member who had previously suggested that such a filter was the cause. Seems he was right, but why hasn't this happened to me previously with my Leica M9 on both Lux and Chron lenses.
look at the area beneath the piano. The pictures being reflected are from a completely different zone in the scene and cannot feasibly be natural reflections on the shiny floor. Other lines on the floor are also suspect so it seems to be an optical anomaly caused by my lens and filter combination.
Ideas?
