I'm really considering making a big upgrade to the URSA, but I've already invested in a fleet of Canon FDs. I've been doing some research on FD to PL mounts without a lot of luck. I know ARRI make an FD adapter to the ARRI mount (PL??) but besides that seems there's zilch out there. Some talk about machining the lenses to fit the new flange but I was hoping someone here knows of something...
