Of course if demand for such an adapter is great enough with cash to back it up, such a third party adapter may be possible … if the math is right.Hasselblad H1 vs Mamiya 645 vs Contax 645 With a S2 and H to S adapter, I can secure H lenses in most any major location should I not want to carry all the S lenses, or should a S lens go down on me.įor the current Hasselblad user like me, the H to S adapter offers more added value because it fills in missing S focal lengths and unlike the C645 optics, all HC and HCD lenses can be used in both Leaf shutter mode to 1/750th and focal plane mode to 1/4000th which is not available on any H camera to date (Photokina may dramatically change that if rumors of a new Hasselblad camera prove to be true, which is highly likely). However, I would hazard a guess that Leica will not make such an adapter because the Contax is a totally discontinued system and doesn't represent an ongoing opportunity in the manner that the broadly used Hasselblad H system does, including pro rental availability. The ability to use the C645 lenses on a S2 would bring an all new ergonomic experience to the Contax owner, similar to use of Hasselblad 645 optics. This may be due to the aging Contax camera bodies and steadfast adherence to many of the Zeiss CZ optics that provide a wonderful character.

There seems to be a growing interest in a fully functional C645 to S adapter. Perhaps an alternative approach might be to find one of the Mamiya 500 f/ 4.5 APO lenses that were produced for the M 645 system. I do understand that in essence, I am asking for a speculative opinion, but would appreciate any thoughts on this subject with specific regard to Contax 645 lenses. My question is wether those with experience with “alternative” lenses on the S2 would advise such an endeavor given the properties of digital sensors and such. I have a substantial experience with the Contax system and have owned the 350 APO Tessar and been extreme y pleased with it in the film mile. I know of an active effort to create an adapter for Contax 645 lenses for use with the S2 which is tauted to offer full metering and auto focus compatibility. One major concern that I have with this system is the absence of an existing long lens at this point and what I presume will be a very long wait for the anticipated APO-Tele-Elmar-S 350mm f/3.5. I am in the process of evaluating an S2 as likely near term purchase.
