Aperture-Priority Auto Exposure Mode (A)
This mode operates with all Nikon lenses. When used with any optical system such as Reflex lens, microscope, telescope, bellows, etc., the F4'smicrocomputer automatically selects the correct shutter speed to match the aperture you set. This is the recommended mode when depth of field is your prime con- sideration. For less distinct backgrounds, as in portraitu re, use larger apertures to obtain a shal low depth of field . For overall sharp, clear pictures, as in scenic photography, use smaller apertures.
