Exposure Viewfinder Information
12mm-dlameter clrcle_ The Nikon FG-20 employs
through-the-Iens (TTL) centerweighted full-aperture
el<posure metering. This means that light passing
through the lens is measured at maximum aperture,
thus assuring a bright finder image during shooting .
Special emphasis is placed on the brightness in the
12mm-diameter central area. So, by placing the main
subject in the center of the frame, you can get the
correct exposure in most situations.
Meter needle_ As soon as the shutter release button
is depressed halfway to activate the meter, the needle
automatically shows the exposure information .

Shutter speed scale. In both the automatic and
manual exposure modes, the meter needle indicates
the cor rect shutter speed, according to the scene

in use.
• For shooting moving subjects, the FG -20 lets you select fast
shutter speeds on auto for freezing the action or slow ones
for producing an intentional blur. To operate the FG -20 in this
way, turn on the exposure meter by depressing the shutter
release button halfway and then rotate the lens aperture ring
clockwise or counterclockwise until the meter needle paints
to the desired shutter speed.
