Extreme Low-Light Metering
The meter built into the Nikon F2SB camera is capable
of metering low-light levels requiring slow shutter
speeds of up to 10 seconds. To meter at low-light levels,
perform the following; Set the lens’ aperture ring to the
desired aperture setting, and the shutter-speed selector
to “B”; then, depress and hold the shutter-speed dial
lock and turn the selector until the center LED exposure
indicator (o) illuminates to indicate correct exposure.
Having set the selector, read off the number on the extra­
long exposure scale and set the camera’s self-timer for
the indicated value; then, set the T-L fingerguard to “T”
and depress the shutter button to make the exposure.
When performing low-light metering, be sure to block the
entry of stray light into the viewfinder by closing the
eyepiece shutter or by continuously viewing through the
finder. (Refer to accompanying photos for details.)
Time Exposures
To make an exposure longer than 10 seconds, set the
shutter-speed selector to “B” and turn the T-L finger-
guard to “T” as described in “Extreme Low-Light Meter­
ing.’’ Advance the film and press the shutter-release
button to open the shutter. As long as the fingerguard
remains set to “T,” the shutter will remain open. When
returning the fingerguard to the normal center position
to close the shutter, be careful not to move or shake the
camera, as a blurred image may result.
