Luisa Ehrich Posted December 14, 2008 Share Posted December 14, 2008 I have a Century Optics Duplikin II that I was hoping to mount to a Nikon D100. Unfortunately, there are no f-mount to c-mount adapters. Does anyone know how I might be able to make this happen? Thanks, luisa Link to comment Share on other sites More sharing options...

Unfortunately, there are no f-mount to c-mount adapters. Does anyone know how I might be able to make this happen? Hi Luisa, unfortunately I doubt that is going to happen easily. The FFD (flange to film distance) of C mount lenses is usually 17.52mm (or 20.76mm for Bolex RX lenses) and the F mount FFD is 46.5mm. Unless you buy or build some kind of relay optics there is no way of forming an image on the D100 sensor. Moving the lens farther in is no option either as the mirror will then hit the lens. AFAIK there were versions of the Duplikin for 35mm still cameras. I didn't even know there was a C-mount version of the Duplikin II!

Kristian Schumacher Posted January 6, 2009 Share Posted January 6, 2009 Actually, I am quite sure I saw somewhere online that this was possible.... I can't remember where, but I really want to do the same thing to test some c-mount lenses. I guess the mirror would have to be locked up in the slr if you are to fit the c-mount far enough back. If anyone knows how to do this, I would also be very interested in this info. Waiting in suspense.... Kristian Link to comment Share on other sites More sharing options...
Luisa Ehrich Posted January 6, 2009 Author Share Posted January 6, 2009 Hi Dave -- thanks for your response. You're right, there isn't a c-mount version of the Duplikin -- I miswrote. What I have is an M42 mount. I'm hoping I can adapt it to the Nikon (without any insurmountable focusing issues) with something like this: http://cgi.ebay.com/M42-Lens-F-Mount-Adapt...5QQcmdZViewItem Link to comment Share on other sites More sharing options...
