More tests with my 'gift' CONTAX RTS II Quartz and the Planar lens -- here is a Window Cleaner in action -- I had to focus quickly before he saw me ! I used outdated Fuji Super G 100 film rated at 64 ASA and home-processed in C41. I think there may be a LIGHT LEAK now in the film plane-- see the red area below -- I had to change the mirror bumper foam as on use it all crumbled after so many years of non-use.
