OPERATION OF CAMERA CONTROLS
Setting the Shutter Speed
The Nikon F2AS Photomic camera can be set to the desired
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 selector 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 second to 1/2000 second. The red line pro-
vided between the 1/60 sec. and 1/125 sec. settings indicates
1/80 second—the fastest shutter speed providing X synchro-
nization for use with electronic flash units. When more pre-
cise 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 but-
ton is depressed. (See “Flash Synchronization” 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 preset the lens
aperture, turn the aperture ring until the desired f/number set-
ting 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 clickstop settings for more precise ex-
posures.
