I hope this doesn't sound heretical, but I've been wondering if there is a effective way to mount one of Zeiss' newer wides onto an Olympus OM body. Does anyone know if such an adaptor ever existed? I've done some web searching but I haven't really come up with anything. I did hear that at one time people could mount Leica R mounts on OM's but I digress. Zeiss has some nice wide angle high speed lenses that would be fun to use on an OM. Like the 28/2 or 25/2. I know Zuiko produced equivelents but I've found modern wides generally outperform older wides. And lets face it, the zuiko lens designs aren't getting any younger.
Not possible, unfortunately. The OM flange-to-film distance is greater than that of most 35mm SLR systems - no space for an adaptor, and you'd need pretty specialised surgery to make one of the Zeiss lenses fit.
This is not just brand loyalty talking, but there really isn't much reason to desire the modern Zeiss lenses on the OM system. The Zuiko 21mm f/2.0 and 24mm f/2.0 are honestly not outperformed in practical terms, considering that you are shooting 35mm film. Olympus' true speciality was making small, ultra-high performance wide angle lenses - the joy of the OM system just wouldn't be the same without it.
The Zeiss lenses are beastly giants (look at the Distagon 21mm f/2.8! A full stop slower, and more distortion to boot. Oh, and they generally feel like cheap 1970s third-party off-brand lenses in terms of build quality, compared to real Zuikos or Nikkors).
If you really want to shoot the Zeiss lenses on film, pick up a Nikon F with plain prism. Beautiful, any OM-1 lover cannot disagree with it, exceptionally well-built (will crush an OM, if it wanted to), and just that bit larger to fit well with the giant Zeiss lenses. Oh, and cheap!
Ask yourself - what compelling feature does any OM body have to even think of a cumbersome off-brand lens mounting solution? And you'd definitely not have auto-aperture, etc. I can't think of any...
