Aperture-Priority Auto Exposure Mode - Nikon F55 - F55 35mm SLR Camera Instruction Manual

Aperture-Priority Auto Exposure Mode

A
Enables you to set the desired aperture (lens'
minimum to maximum) manually. The camera
automatically selects a shutter speed suitable
for correct exposure.
• A (Aperture-Priority Auto) can only be used with a
CPU Nikkor lens such as G- or D-type Nikkor (page
88).
Small aperture f/32
• In flash photography, varying the aperture changes
the flash shooting distance (page 83).
By varying the aperture, and thus controlling the
depth of field (page 86), you can sharpen the
background and foreground, or blur the background.
Large aperture f/2.8

NOTE: CPU Nikkor lenses other than G-type
Always set the aperture ring of a CPU Nikkor lens (except G-type) to its minimum
(largest f-number). When the lens is not set to its minimum aperture setting,
blinks in the LCD panel and viewfinder, and the shutter locks.
