I have the 80-400VR, and the VR cannot be left on when mounted on a tripod. On the newer, more expensive lenses, specifically the 200-400VR and 300 f2.8 VR, can the VR be left on without any issues when mounted on a tripod?
The idea is that your camera will be fairly well locked down on the tripod, and the VR will not have any “give” as it does when you are hand holding, and therefore cause more vibration. The only thing I have with VR is the 70-200, and you can feel it engage so see how this might be true. If my shutter speed is fast enough I turn it off anyway, so I really don’t have much experience with the issue…just passing along what I understand.Out of curiosity, why cant you use VR on a tripod?
