Operation Manual

Movie scale (6)
Measuring the exposure for movie cameras is performed
in exactly the same way as that for ordinary still cameras
except that the number of frames (8, 16, 32, etc.) is
taken into consideration. Read out the value on the
f/number scale (8) which best agrees with the number of
frames of the movie camera and then transfer this setting
to the camera. With a movie camera shutter open
angle of 180°, the standard number of frames is 24,
and this is indicated by the black line. The standard
number of frames with single 8 and super 8 movie
cameras is 18 and this is indicated by the black dot.
EV scale
If your camera has an exposure value type of shutter,
determine the exposure using the exposure value scale
(EV scale). If you are, for instance, using an ASA100 film,
set the EV scale to '10' with an EV10 value. If the
f/number of the camera is set to 5.6 at this value, the
shutter speed will automatically go to 1 /30 sec. and to 1
/8 sec. with an f/11 setting.
