It is a real pleasure to work with but I have a problem with newtonrings. This is caused by the condensor which has no anti-newton layer and has direct contact with the negative. Leitz used to have anti-newton glas which is discontinued. I tried to avoid contact between the negative and the condensor by masking the 24x36mm image with tape but it did not work. Is someone familiar with this problem ? Thanks a lot in advance for your tips. Greetings, Frederik Boone
