• Do not turn the camera power OFF or remove the lens from the camera
while the vibration reduction mode is in operation. (Otherwise, the lens
may emit a chattering noise if the camera is shaken. This is not a
malfunction. Turn the camera power ON again to correct this.)
• With cameras featuring a built-in flash, vibration reduction does not
function while the built-in flash is charging.
En
• When the lens is mounted on a tripod, set the vibration reduction ON/OFF
switch ( to [OFF]. However, set the switch to [ON] when using a tripod
without securing the tripod head, or when using a monopod.
4. Focusing, zooming, and depth of field (p.98)
First turn the zoom ring 5 until the desired composition is framed in the
viewfinder before focusing. If your camera has a depth of field preview (stop-
down) button or lever, depth of field can be observed while looking through
the camera viewfinder.
• The distance scale does not indicate the precise distance between the
subject and the camera. Values are approximate and should be used only
as a general guide.

5. Variable maximum apertures

Zooming the lens from 70mm to 300mm decreases the maximum aperture
approx. 2/3 of an f/stop. For cameras with TTL metering, there is no need to
adjust the aperture. Likewise, for TTL auto flash photography with Nikon
Speedlights, no adjustment is required. When using a separate exposure
meter or taking photographs in the non-TTL flash mode, select the
appropriate aperture value according to the focal length setting as displayed
on the camera.
