Thanks for the VR advice I did not know that. But why is it better with VR off and does the same apply for mono pods?
The idea behind VR is to stop or reduce any kind of shake or vibration, eliminating or severely reducing blurry photos. When mounted on a tripod, VR becomes redundant. The camera is securely mounted, not moving, so no need for the VR function.
On a monopod, there is no absolute stability, just on the up and down plane. There's still the possibility of side to side movement, so VR would be used to reduce movement...........although, depending on what you're shooting, this would be a judgement call, based on experience, and how steady you are while focusing.
