My thoughts go to making photographs with lenses and that the lens doesn't stand alone. It's has a camera to go along with it. So, I lens should be tested with film on the camera, not on an optical benchwhich gives you theoretical answers that are electonically converted into make-believe prints. One concern is the film channel of a camera. Bob Schwalberg noted much about this to me during our many lunches in the big apple. For example: The screw-mount Leica's film channel is not so good. The M camera is much better. The old Nikon F was excellent. The Carl Zeiss Ikon Contarex was excellent. The tolerance on how the film is held in place during exposure is a consideration. Ask Norman Goldberg about this. He's the expert. Also, when the cameras started to shrink in size (Olympus OMs) we became concerned about the stabilization of the film while held in the channel for the exposure. If the film comes right off the cartridge without a certain distance for it to be held flat, perhaps the film will not be so flat in the channel? Yes and no. It's a consideration. When you make cameras with excellent film channels, you probably end up with large cameras and people like to buy small cameras. So, make pictures with cameras and lenses. I think that's what they are made for. Ed
