Javed Haque Posted October 31, 2013 Share Posted October 31, 2013 Can I use C mount lenses on Arri SR2 by way of an adapter? where can I find adapters? Link to comment Share on other sites More sharing options...
Heikki Repo Posted October 31, 2013 Share Posted October 31, 2013 Unfortunately it can't be done. Flange focal distance of C-mount lenses is too short to be able to use them with Arri. Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted November 1, 2013 Premium Member Share Posted November 1, 2013 There is a very dodgy seller on ebay (and now with an online store) selling $99 adapters to use C-mount lenses on PL mount cameras, a complete rip-off since the C-mount lens will seat very far out from where it needs to be and only focus a few inches away. The seller pretends not to know if infinity focus is possible, claiming he hasn't checked every lens/camera combination. Don't be sucked in by this ploy, no C-mount to PL adapter will work, the difference in flange depth is too great. Even if you found an adapter that held a C-mount at its correct flange depth (about 35mm inside the PL flange) you wouldn't be able to reach the focus or iris rings, and with reflex film cameras there is a spinning mirror in the way. This adapter: http://www.calkovsky.com/c-mount-to-pl-mount-lens-adapter/ which may or may not be the one I'm referring to, will avoid hitting a reflex mirror, but seats the lens roughly 3cm further out from the film plane than it needs to be. Fine if all you want to do is film insects. Link to comment Share on other sites More sharing options...
