(8).
At the same time. the speed knob of the camera

In this way,
the correct

Importontl
On lenses

- e. g. 8 - and then rotating the control knob (3) to centre
the
meter
needle
to the fixed
mark. Also in this case ASS lenses
have to be stopped
down by means of lever
(17).
The exposure speed
now nearest
to the index
mark
(8) has to
be transferred
to the camera.
Fine adjustment
is made
by
movement
