Set the film speed setting which you intend to use. How to set the film speed For, the correct setting on the ASA scale (8), rotate the ASA set knob (9) and align the white mark on the black dial with the red scale unit in the ASA window.

Reading out the exposure

Specifications
Measurement system: Reflected light system Measurement range: EV7 to 17 (ASA 100) Angle of incoming light: 65 Scales:* ASA (DIN).6 (9) to 12000 (42) * f/number. 1 to 64 * Shutter speed (T). 8 to 1/2000 sec. * EV. -2 to 19 Dimensions : 81 x 52 x 24.5mm Weight : 50g
When the sensor (1) is pointed in the direction of the subject, the pointer (2) deflects in accordance with the brightness of the subject. To read out the exposure, rotate the dial ring (11) and set so that the pointer (2) is aligned with the center of the guide mark. The correct exposure wi ll be the combination of the shutter speed scale (5) unit on the dial and the f/numher scale (6) unit.
In the illustrated example, f/5.6 will be the correct exposure at 1/125 sec. and f/8 at 1/60 sec.

Dial scales

The numbers /2, /4 and /8, etc. on the shutter speed scale (5) signify 1/2, 1/4, 1/8 sec. etc., and the numbers 1, 2 and 4, etc., signify 1, 2, 4 sec., etc. The numbers 1.6M, 3.2M, etc. on the ASA scale (8) signify 1600, 3200, etc.

Interim scale units

The interim units on the dial scales are as follows: Interim values of the ASA scale (8) [DIN scale (7)]

Movie scale (4)

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 (6) 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 for play films 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 scales). 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 1 /8 sec. with an f/11 setting.
