Setting the Shutter Speed

The Nikon F2S8 Ph otom ic camera can be set to the de- ~ired shutter speed either before or after the shutter is wound. Speeds of from 1 second to 1/2000 second are set via the sh utter-speed selector f itted on the finder; the se lector is a lso provided with a "8" setting for longer time exposures. To set the shutter speed, turn the selec- tor until the desired speed is a ligned with the white dot; when a ligned with setti ngs of from 2 to 2000, the actua l shutter speed will be a fractiona l value of from 1/2 sec- ond to 1/2000 seco nd . The red line provided between the 1/60 sec. and 1/125 sec. setti ngs ind icates 1/80 seco nd - the fastest shutter speed providing X synchroni- zation for use with electronic flash units. When more precise settings are required, intermediate shutter speeds

of fro m 1/80 sec . to 1/2000 sec. are usable. At the "8" 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 a ligned with the ind ex mark provided on the lens. The iris diaphragm can a lso be set to intermediate apertures between the click- stop settings for more precise ex posures.
