21En■Setting the vibration reduction ON/OFF ring switch (Fig. E)ON: Vibration is reduced while the shutter release button is lightly pressed and also at the instantthe shutter is released. Because vibration is reduced in the viewfinder, auto/manual focusingand exact framing of the subject are easier.OFF: Vibration is not reduced.■Setting the vibration reduction mode switch (Fig. H)First, set the vibration reduction ON/OFF ring switch ON, then select the following mode:NORMAL: The vibration reduction mechanism primarily reduces camera shake, making smoothpanning shots possible.ACTIVE: The vibration reduction mechanism reduces camera shake when taking pictures andthose from a moving vehicle. In this mode, the lens does not automaticallydistinguish panning from camera shake.■Notes on using vibration reduction• Wait until the image in the viewfinder stops vibrating before fully depressing the shutter releasebutton after you have lightly pressed the shutter release button.• When taking panning shots, be sure to set the vibration reduction mode switch to NORMAL. Ifyou move the camera in a wide arc when panning, vibration in the direction of that movement isnot affected. For example, if you pan the camera horizontally, only vibration in the verticaldirection is reduced, making smooth pans much easier.• Due to the characteristics of the vibration reduction mechanism, the image in the viewfinder maybecome blurred after releasing the shutter.• Do not turn the camera power OFF or remove the lens from the camera while the vibrationreduction mode is in operation. (Otherwise, the lens may emit a chattering noise if the camera isshaken. This is not a malfunction. Turn the camera power ON again to correct this.)• With F80-Series/N80-Series, F75-Series/N75-Series, F65-Series/N65-Series, D100 and D70cameras, vibration reduction does not work while the built-in flash is recycling.• Set the vibration reduction ON/OFF ring switch to ON when the lens is mounted on a tripod. Theswitch should be set to ON when using a tripod without tightening the tripod head, or when usinga monopod.• If you set the AF start (AF-ON) button to ON on the camera or the Focus operation button on thelens, vibration reduction will not operate.5. Depth of fieldIf your camera has a depth of field preview (stop-down) button or lever, depth of field canbe observed while looking through the camera viewfinder.6. Setting the apertureBecause this lens does not have an aperture ring, you must set the aperture on the camera.
