Hello there.
I am about to use an arriflex 16bl. I have only done still photography up untill now. How do i know what the shutter speed is on the camera so i can set the correct exposure? I think the mirror shutter angle is 180, i am thinking that means the shutter speed would be twice as fast as whatever the fps is set at. Is this correct?
Thank you,
Oscar.

Yes, sort of. At 24 fps with a 180 degree shutter (a intermittent spinning half circle, so the gate is closed 50% of the time) the exposure time is 1/48th of a second.
