First Steps

Attaching a Lens

Autofocus is supported with AF-S and AF-I lenses only. Care should be taken to prevent dust from entering the camera when exchanging lenses.

1 Turn the camera off and remove the body cap.

Remove the rear lens cap from the lens.

2Keeping the mounting index on the lens aligned with the mounting index on the camera body, position the lens in the

camera’s bayonet mount and rotate the lens in the direction shown until it clicks into place.

If the lens is equipped with an A-M or M/A-M switch, select A (autofocus) or M/A (autofocus with manual priority).

Detaching Lenses

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. After removing the lens, replace the camera body cap and rear lens cover.

Aperture Ring

If the lens is equipped with an aperture ring, lock aperture at the minimum setting (highest f/-num- ber). See the lens manual for details.
