❚❚ Vibration Reduction (VR)

Vibration reduction can be enabled by sliding the 
vibration reduction switch to ON and takes effect 
whenever the shutter-release button is pressed 
halfway. Vibration reduction reduces blur caused 
by camera shake, allowing shutter speeds up to 4.0 
stops slower than would otherwise be the case and increasing 
the range of shutter speeds available. The effects of VR on 
shutter speed are measured according to Camera and Imaging 
Products Association (CIPA) standards; FX-format lenses are 
measured using FX-format SLR digital cameras, DX-format lenses 
using DX-format cameras. Zoom lenses are measured at 
maximum zoom.

• When using vibration reduction, press the shutter-release button 

halfway and wait for the image in the viewfinder to stabilize before 
pressing the shutter-release button the rest of the way down.

• When vibration reduction is active, the image in the viewfinder may 

jiggle after the shutter is released. This does not indicate a 
malfunction.

• When the camera is panned, vibration reduction applies only to 

motion that is not part of the pan (if the camera is panned 
horizontally, for example, vibration reduction will be applied only to 
vertical shake), making it much easier to pan the camera smoothly in 
a wide arc.

• Do not turn the camera off or remove the lens while vibration 

reduction is in effect.

• If the camera is equipped with a built-in flash, vibration reduction will 

be disabled while the flash charges.

• Select OFF when the camera is mounted on a tripod unless the tripod 

head is unsecured or the camera is mounted on a monopod, in which 
case ON is recommended.
