I always thought that VR was meant to be off on tripods or monopods, excepting some Canon L lenses. VR is meant to detect human wobbly arms which wobble in a different way to tripods and monopods. I can't see VR coping with a windy day, blowing hard enough to move your monopod & lens around ?
I'm just questioning the value of VR on a lens thats hardly ever going to be hand held ( if at all ) And unless VR tech has gone to another level, you have to give VR time to settle before shooting which makes BIFs and other Wildife on the hoof ( which is surely where this lens would be used most ) rather difficult to shoot - as they've disappeared by the time you hit the shutter
Happy to be proved wrong though !
