The Bolex I am using is a H-16 Refex. I'm unsure if it is one of the REX-1 through REX-5s, but it's serial number begins with 203.
I was wondering how much I should compensate for light lost in the reflex, or if the wider (narrower?) shutter angle already compensated for this. I will be shooting at 24fps but have been told variously to meter for 1/60th shutter speed or 1/80th. Now I am just really confused. Any one shot on this or can shed some light on the matter?
