❚❚ 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. D Vibration Reduction • 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. 318 Technical Notes
