3. Mounting a Lens

Nikon recommends using a G- or D-type CPU lens to take full advantage of the features the camera offers.

CPU Nikkor lenses have	G-type Nikkor lens	D-type Nikkor lens
CPU contacts

1 Turn the power switch off.

• Turn the power switch off before mounting or detaching lenses.

2 Mount the lens to the camera body.

• Position lens in the camera’s bayonet mount so that the mounting indexes on the lens and camera body are aligned, then twist the lens counterclockwise until it locks into place.

• Be sure not to touch the lens release button.

3 Lock aperture at the minimum setting.

• With a CPU Nikkor lens other than G-type, set the lens to its minimum aperture (smallest f/stop) and lock. When a CPU Nikkor lens other than G-type is not set to its smallest aperture setting and the power switch is turned on, ƒEE will blink in the top LCD panel and viewfinder and the shutter cannot be released.

•G-type Nikkor lenses have no aperture ring. Unlike other CPU Nikkor lenses, aperture does not need to be set to minimum.

•Detaching the lens

• Turn the power switch off, push and hold the lens release button Å, then turn the lens clockwise Í.
