Detaching Non-Waterproof Lenses
Before removing or exchanging lenses, turn
the camera off. To remove the lens, press and
hold the lens release button (q) while turn-
ing the lens as shown (w). After removing
the O-ring protector from the camera, clean
any foreign matter from the O-ring and
replace the lens caps and camera body cap,
and then clean the O-ring protector with a soft cloth and place the pro-
tector on the front of the body cap.

Lenses with Retractable Lens Barrel Buttons
The camera will turn on automatically when the retractable lens
barrel lock is released; in addition, if the view through the lens is dis-
played or the monitor is off, the camera will turn off when the lens
barrel is locked (in the case of 1 NIKKOR VR 10–30mm f/3.5–5.6 and
1 NIKKOR VR 30–110mm f/3.8–5.6 lenses, firmware version 1.10 or
later is required if locking the lens barrel is to turn the camera off
when the monitor is off; for information on updating lens firmware,
visit the Nikon website for your area).
The lens can be retracted and the zoom ring locked by pressing the
retractable lens barrel button and rotating the ring in the opposite
direction. Be careful not to press the retractable lens barrel button
while attaching or removing the lens.

Optional Lenses with Power Drive Zoom Switches
Slide the power drive zoom switch to T to

which the camera zooms in and out varies
with how far you slide the switch. The zoom
position is shown by the zoom guide in the
