Set the desired f/stop on the Aperture
Ring

the red reference dot
(The Aperture

In-between clicks can also be used.)
AM (Auto/Manual) Lever
1. In normal photography, set AM
Lever so that character “A” is visible
in the lever window. If you do so,
the aperture will remain wide open,
stopping the lens down only during
shutter operation.
2. Moving the AM Lever of the lens so
that “M” is visible will stop the lens
down to the preselected aperture,
thus making it possible to confirm
effect of the aperture through the
viewfinder.
