Interesting Letter or the week in AP dated 3 August. Should you turn image stabilisation off when using a tripod, or not? I have to say that the author was right to ignore the "advice" to turn the stabilisation off, and indeed the comment about graduated filters. However, I would say that one should be guided by the camera and/or lens manufacturer. If the manufacturer says switch off or change mode when using a tripod they have probably done the research to support that advice. I've never used my one VR lens on a tripod so I have no idea what, if any, effect it has but before using it on a tripod I would check with Nikon this is what they say: "When the camera is mounted on a tripod there will be very little, if any movement. If the VR function is turned on when used on a tripod, this may result in a reduction in image quality as the VR system attempts to adjust for any slight vibration which will not normally affect the image." There is then a list of lenses that can cope wit having VR switched on when using a tripod. As always, if it works for you, get on with it, there is no "right" way to do things.
