oduction—First Steps
Getting the Camera Ready for Use
5 .3 Lock aperture at the minimum setting
This step is not necessary if you are using a type G lens (type G lenses
are not equipped with an aperture ring). If you are using a lens of
another type, lock aperture at the minimum setting (highest f/-number).
If you do not perform this step when using a CPU lens, the aperture
displays in the control panel and viewfinder will show a blinking
when the camera is turned on. Photographs can not be taken until you
have turned the camera off and locked aperture at the highest f/-num-
ber.
Detaching the Lens
Be sure the camera is off when removing or exchanging
lenses. To remove the lens, press and hold the lens-
release button while turning the lens clockwise.

Non-CPU Lenses
Non-CPU lenses can only be used when the function dial is set to M (manual exposure
mode). In other exposure modes, the shutter release will be disabled. When a non-
CPU lens is attached, the camera exposure meters will not function, and the aperture
displays in the control panel and viewfinder will show
to indicate that aperture can
only be set using the lens aperture ring.
