I was wondering if there was any way to convert a C/Y mount to PL mount without a full rehousing. I would love to have a set of MMJ Contax Zeiss lenses in PL mount but so far I haven't seen little to any information regarding this subject. I know it's possible to convert a C/Y mount to M42 so maybe it would be possible to convert it to M2 first, then screw on an M42 to PL adapter which might work on few C/Y lenses but I know for sure the diameter of the particular Contax lenses I want would be too wide to fit inside of the adapter. And I I know It wouldn't be possible to make the flange of the PL mount adapter flush with the flange of the C/Y Mount because the flange focal distance of a C/Y mount needs to be 45.50 mm from the film plane and a PL mount needs to be 52.00mm from the film plane so in theory would need to remove 6.5mm worth of material from the rear of the lens to accommodate for the difference in FFD (Which wouldn't normally be TOO hard), however of course on majority of the C/Y lenses the aperture ring is pretty much right up against the flange of the mount. I guess I could remove the aperture ring but then what? Maybe someone has any input as to how I could possibly pull this off but I believe I've hit a dead end.
Good evening everyone! Looking to get a hold of a set of old Cooke Panchros to send in for re-housing at P+S in Germany or somewhere else where they do it! In my attempt to get a hold of a set of old-housed Panchros in suitable condition -- how important is it that the lenses are in absolute perfect condition? Almost all older lenses show some sign of wear like fungus, oil on the aperture blades and/or dust inside. Is that extremely critical or is it standard praxis that the re-housing tech firms clean the interior of the optics at the same time they do the re-housing? If not, are fungus, oil on the aperture blades and dust on the inside something that can get fixed for a reasonable price? Any guidelines on price per lens? What about cleaning marks or small scratches? I see a lot of advertisements about scratch-fixes etc. Can it be done in the first place and secondly, can it be done for a reasonable price? I'm not looking to spend the same amount I buy the glass for in cleaning fees. If that's what I should expect, I will go for another set of lenses. Let me know if you have any experience on the matter! Thank you!
