Keep the Lens Stabilisation ON only when the camera is handheld.
Nikon calls it (VR) or Vibration Reduction” & Canon calls it IS or Image Stabilization” It helps to stabilize our image when you’re forced to hand-hold your camera; so do we keep it on all the time ? The answer is NO.
You should always make sure to turn it OFF when your camera is on a tripod.
How does the stabilization technology work ? The stabilization technology works by unlocking part of your lens. This helps the lens to “correct” movements. But, when your camera is sitting still on a tripod, the stabilizer will often look for movement that isn’t there, resulting in a blurry photo. See the example below in which camera was locked onto a stable tripod. In the image on the left, the lens stabilization turned OFF. And, then it is turned ON for the image on the right.
In both the photos all parameters were the same, the only difference was that lens stabilization was turned ON in the photo on the right.
