Hi, I’m new to this forum and I have a question that I hope that someone with a knowledge of Todd AO anamorphics might be able to give me some clues about. I have a Todd AO 35 front element that I bought on Ebay some time ago. I’m trying to find out which focal length this element should have (as in, the focal length on the taking lens). And also, whether this is the early or later version of the Todd AO’s. I was thinking that if I can figure out which taking lens to use, I could get an old Canon K35 lens and have the whole thing built into a fully functioning anamorphic lens by Kim Camera or the like. So, I’m reaching out to anyone who might have a clue as to which lens size this element would fit with. The front is 122mm and the rear is 48mm. I would be grateful for any clues, and any pointers before I embark on this project!
