Auto-Exposure Lock - Nikon D1 Manual

Auto-Exposure Lock

When spot or center-weighted metering is used in combination with pro-
grammed auto, shutter-priority auto, or aperture-priority auto, the camera
determines exposure automatically with reference to lighting conditions in a
limited area of the frame. Auto-exposure lock is used when you want auto
exposure to be based on a subject that will not be in the focus area in the final
composition.
To use auto-exposure lock:
1
With the metering selector lock release held down,
rotate the metering selector to select center-
weighted or spot metering.
2
After positioning the subject in the focus area, press the shutter-release
button half way and confirm that the in-focus indicator ( ) appears in the
viewfinder (A). With the shutter-release button held half way down, press
and hold the button (B).

Exposure is calculated based on lighting conditions in the current focus
area (spot metering) or in an 8mm circle in the center of the viewfinder
(center-weighted metering).
Notes
Matrix metering is not recommended for use with auto-exposure lock, as it is unlikely
to produce the desired results.
Note that if autofocus (single servo AF or continuous servo AF) is in effect, focus will
lock when the button is pressed. Check to see that the in-focus indicator ( ) is
displayed in the viewfinder. If desired, camera settings can be changed so that only
auto-exposure is locked when the

If spot metering is used in combination with closest-subject priority (see "AF Area
Mode"), exposure will be based on lighting conditions in the center focus area.
