Film Speed Dial
The ISO setting on the Film Speed Dial, see Fig. 4, communicates the film’s ISO to the AE prism finder. Be

Make sure that the film leader’s Double Arrow indicator aligns with the ‘Start’ mark on the Roll Film Insert.
When the Film Holder is attached to the camera body, rotate the Crank until it stops, see Fig. 6. The Film
Counter Window will display ‘1’.
When the Film Holder is not attached to the camera body, turn the Film Holder’s Advance Knob until it
