It seems the standard incident meter exposure time for 24fps is 1/50th of a second. My R16 gives a 1/62nd exposure time with a guilotine shutter. the exposure time in my S-8 manuals for 150 degree shutters at 24fps state 1/58th second exposure. a difference of about 1/3rd stop if I meter at 1/60th of a second. just an observation, I'm wondering if the 1/50th is a rounded figure?

there is an eqation that states this: shutter angle/360 X 24fps= exposure time
