OPERATION OF CAMERA CONTROLS
Setting the Shutter Speed
The Nikon F2SB Photomic camera can be set to the de­
sired shutter speed either before or after the shutter is
wound. Speeds of from 1 second to 1/2000 second are
set via the shutter-speed selector fitted on the finder; the
selector is also provided with a “B” setting for longer
time exposures. To set the shutter speed, turn the selec­
tor until the desired speed is aligned with the white dot;
when aligned with settings of from 2 to 2000, the actual
shutter speed will be a fractional value of from 1/2 sec­
ond to 1/2000 second. The red line provided between
the 1/60 sec. and 1/125 sec. settings indicates 1/80
second—the fastest shutter speed providing X synchroni­
zation for use with electronic flash units. When more
precise settings are required, intermediate shutter speeds
of from 1/80 sec. to 1/2000 sec. are usable. At the "B”
setting, the shutter speed remains open as long as the
shutter-release button is depressed. (See “Flash Synchro­
nization” on page 34 for additional information on flash
photography.)
Setting the Aperture
The ring fitted at the base of the lens adjusts the size of
the aperture (or opening) in the iris diaphragm. To pre­
set the lens aperture, turn the aperture ring until the de­
sired f/number setting on the scale is aligned with the
index mark provided on the lens. The iris diaphragm can
also be set to intermediate apertures between the click­
stop settings for more precise exposures.
