Hi, all, long time reader first time poster.

My situation is that I bought a C mount camera which will arrive next month, after purchasing some Arri Bayonet Primes.. I did not think there would be a problem in finding a suitable adapter, but I have been very wrong.

Will it be possible to use the AB - PL adapter I have, and attach that to the PL- C adapter that will be coming with the camera. Or will there be too much of a gap between the glass and camera to attain focus?

Please let me know folks, I may have time to sell the AB lenses and get some C primes in time for my cameras arrival.

Thanks in advance.

Arri flange focal depth is the same for PL and bayonet :52mm. Unless the adaptors are off specs, you should not have a problem..........unless they're going on a Bolex. Then the lenses should have Bolex Rx mounts.

Yes, it should be fine, I've used that combination of adapters without a problem. As long as the adapters are properly made.

If you want to rely on the focus distance scales of the lenses you'll want to get their back-focus checked when mounted to your camera, as each adapter will add a little more potential variation to that critical distance.
