I have a Zeiss 85mm f1.2 (50th anniversary) lens which originally had a Contax/Yashica mount. When I bought the lens it came with an Aaton mount. I want to install an EF conversion mount which I bought from Simmod, but it requires the original C/Y mount to be present, in order for it to attach to and I guess sit at the right height for flange distance etc. I've tinkered with making a shim/spacer out of a Canon lens cap, but it's not exactly as good as a nice machined metal part. And it requires me to find longer screws.. Anyway, my questions would be: 1) What is the correct distance from rear element of this lens to sensor/film plane? 2) Is there a way to source a C/Y mount for this particular lens? (Note it's quite a bit wider at the base than many potential "donor" contax lenses, I know because I've already destroyed a 50mm f1.7 *sorry) 3) Do spec sheets, blueprints, technical data or papers exist in a public domain for this particular lens? 4) Could someone please point me in the direction of a good resource for understanding how the C/Y mechanism works? I seem to have begun my lens *home servicing journey on a rather expensive lens, and I'm pulling a few too many hairs out with anxiety... Many thanks and hello!
Hello, Does anyone know of a camera technician in Los Angeles who works on 16mm cameras, specifically Eclair NPR and Beaulieu? I need someone to remove the ground glass, mark it (with a pencil is fine), and replace it in an Eclair NPR camera that's already been (partially) modified to super 16mm. The eyepiece has an issue as well, where one side of the frame is cut off, I assume because of the lens re-centering in the super 16 conversion. The image on my test reel looks great, but my framing was off because of the inaccurate ground glass markings and eyepiece problem. Also, I have a Beaulieu 16mm clockwork camera and need to figure out why my focusing has been occasionally off even though I've got the eyepiece diopter calibrated - at least the way I think it needs to be calibrated. I'm looking for a camera technician in Los Angeles who would go over the camera with me and possibly convert it to Ultra 16mm. The Eclair has been to Bernie O'Dougherty who gave it a clean bill of health, but he was too swamped to do mark the ground glass. The cameras and I are in Los Angeles. Thanks for reading and considering this! -Roko (brand new member)
