Exposure Mode

Exposure mode determines how the camera sets shutter speed and aperture when adjusting exposure. Four modes are available: programmed auto (P), shut- ter-priority auto (S), aperture-priority auto (A), and manual (M).

Depth-of-Field Preview

To preview the effects of aperture, press and hold the depth-of-field preview button. The lens will be stopped down to the aperture value selected by the camera (modes P and S) or the value chosen by the user (modes A and M), allowing depth of field to be previewed in the viewfinder (the built-in flash and optional SB-800, SB-600, and SB-R200 Speedlights will emit a modeling flash).

CPU Lenses

When using a CPU lens equipped with an aperture ring, lock the aperture ring at the min- imum aperture (highest f/-number). At other settings, the shutter release will be disabled and a blinkingwill appear in the aperture displays in the control panel and viewfinder. Type G lenses are not equipped with an aperture ring.

b1—ISO Auto ( 152)

When Custom Setting b1 (ISO Auto) is on, the camera automatically varies ISO sensitivity between ISO 100 and a maximum selected by the user to help ensure optimum exposure and flash level. In exposure modes P and A, the camera adjusts ISO sensitivity when the shutter speed needed to obtain optimum exposure would be faster than / s or slower than a specified value. Otherwise the camera adjusts ISO sensitivity when the limits of the camera exposure metering system are exceeded (mode S) or when optimum exposure can not be achieved at the shutter-speed and aperture selected by the user (mode M).

e4—Modeling Flash ( 166)

If Off is selected for Custom Setting e4 (Modeling Flash), the built-in flash and optional SB-800, SB-600, and SB-R200 Nikon Speedlights will not emit a modeling flash when the depth-of-field preview button is pressed.
