Nikon D200BODY, D70-series, D200KIT Adjusting Shutter Speed and Aperture, Metered Area, C1-AE Lock

Adjusting Shutter Speed and Aperture

While exposure lock is in effect, the following settings can be changed without altering the metered value for exposure:

Exposure mode	Settings
Programmed auto	Shutter speed and aperture (flexible program; 63)
Shutter-priority auto	Shutter speed
Aperture-priority auto	Aperture

The new values can be confirmed in the viewfinder and control panel. Note that the metering method can not be changed while exposure lock is in effect (changes to me- tering take effect when the lock is released).

Metered Area

In spot metering, exposure will be locked at the value metered in a 3-mm (0.12 in.) circle centered on the selected focus area. In center-weighted metering, exposure will be locked at the value metered in an 8-mm (0.31 in.) circle at the center of the viewfinder.

c1—AE Lock ( 156)

If +Release Button is selected for AE Lock, exposure will lock when the shutter-release button is pressed halfway.

c2—AE-L/AF-L ( 156)

Depending on the option selected, the AE-L/AF-Lbutton locks both focus and exposure (the default setting), only focus, or only exposure. Options are available for keeping exposure locked until the AE-L/AF-Lbutton is pressed a second time, the shutter is released, or expo- sure meters turn off.
