Interesting thing happened the other day. I recently started shooting Neopan 400 in 35mm and love the film. I as on a shoot this week and shot a couple of rolls through one of my MP's. I processed one roll that evening along with some 120 and discovered vertical bands in the film. Looking at the frame as a horizontal the bands were about 2mm's wide and ran the short dimension fo the film. Every frame didn't have it and they were in different places in each frame that had them. After the 13th frame there were no more untill I reached the end fo the roll. It appeared as if I was shooting at 1/500 and someone fired a strobe during my exposure. The band was higher density than the rest of the frame with distinct edges. The strange thing was I was the only person shooting and the exposures were 1/30-1/60 which ment the shutter as totally open or near so for each exposure. I also noticed the band started at the bottom of the frame and didn't extend all the was through the frame. Some of the bands were in the center of the frame and some were nearer the edge. Nothing extended into the sprocket area. The film was loaded in a dim lit area and unloaded in the same. I had the problem with a variety of lenses, 21mm Elmarit, 75 Summilux and 90 asph apo Summicron. I was concerned my shutter was having a problem so I did a test roll under the same conditions. I shot the test with my 50 asph summilux that I rarely use. I noticed outside that the infinity alignment was off and blamed it on the camera. I checked the body with another couple of lenses and the focus was OK with them. I took the asph summilux and checked it on a couple of other M's and it was off just like the first body. I then processed the second test roll shot at 1.4 and the 50 and found it to be extremely soft in focus but absolutely no signs of banding. I shot another roll and found the same thing and no banding.
Now I feel confident the body is fine but the asph summilux is out of whack. I understand it's a fairly complex lens with the cams and floating element so things could drift. Has anyone else seen this problem with their 50 asph and have any of you had problems with Neopan?
