HOW VR WORKS
Many Nikon lenses have Vibration Reduction built in (you can identify them by ‘VR’ in the name). Here’s how VR works…
01 Inside the lens, gyroscopic sensors detect any movement and instantly counteract it by moving a ‘floating’ lens assembly which keeps the image steady.
02 Strictly speaking, you should switch the VR off when the camera’s on a tripod because it could introduce vibration. In practice, most of us forget and it doesn’t seem to be a problem.
03 If you’re shooting handheld you can leave the VR switched on all the time. VR doesn’t guarantee sharp shots, but it does improve your chances of good results when you’re using marginal shutter speeds.
04 Some lenses have a special Active mode. This is designed for situations when you’re being badly shaken about as you’re taking pictures – if you’re shooting from a moving vehicle, for example.
Many Nikon lenses have VR, and some have ‘Normal’ and ‘ Active’ modes as well
