The aperture and
preset rings
of the

enable
focusing at full aperture for the
brightest viewfinder
image, with rapid
setting of
the diaphragm to the pre-
set shooting aperture.
Having
set
the preset ring to
the
desired
aperture setting, focus as follows:
Turn the
aperture
ring
to
the
f/2.8 setting
to
open
the diaphragm
fully for focusing
(photo 1)
;
then
turn the
focusing
ring until the image
on the
focusing
screen
is in
sharp
focus (photo 2). Before releasing
the shutter,
turn
the
aperture
ring until It
contacts
the preset ring
and
can
no longer be turned
-
the
diaphragm is now at the pre-
set
shooting
aperture
(photo 3).
