Can I use C mount lenses on Arri SR2 by way of an adapter? where can I find adapters?

Unfortunately it can't be done. Flange focal distance of C-mount lenses is too short to be able to use them with Arri.

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:

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.
