The Auto-Lumi is a very handy carry-
arround exposure meter. It allows the ex-
posure to be measured very easily thanks
to its pointer-tracking system which is
based on the guide mark.

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

When the sensor (1) is pointed in the direction
of the subject, the pointer (2) deflects in accord-
ance 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
will be the combination of the shutter speed
scale (5) unit on the dial and the f/number scale
(6) unit.

In the illustrated example,

/5.6 will be the correct (9)
exposure at 1/125 sec. and if

£/8 at 1/60 sec.
