FOCUSING

The aperture and preset rings of the PC-Nikkor 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

; 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 shoot
ing
aperture (photo 3).
