IS while on tripod???
Hello all. I know you are supposed to turn IS off while using a tripod. I went out this afternoon shooting wildlife and forgot to turn it off. All of my pictures are out of focus and blurry. Does IS really have that strong of a an effect??? Thanks...

IS (or Nikon VR) when turned on, looks or "hunts" for movement, when it can't find any, it keeps hunting, creating it's own vibration..

Thats makes sense but I had no idea to what exteme it would actually cause an unfocused image...

The effect should be more of motion blur, not out of focus. The amount of the blur depends on the shutter speed, focal length of the lens, stability of the camera/lens/tripod and the type (vintage) of the IS on the lens..

Early versions of IS are always on, will 'hunt' attempting to stabilize the lens, overcompensate and introduce some motion blur. Later versions of IS have a motion 'threshold' to decide if a tripod is being used - below this level the lens turns IS off, above this level and IS is turned on. If the tripod gets bumped before the shot, a strong wind blows briefly, etc. the IS may get turned on briefly and introduce some motion blur..

Normally I turn it off but I completely forgot during this last outing..

Would you also turn it off when using other objects (hand railings, walls, ect...) as a tripod????..

Comment #4

I wouldn't turn it off in those cases, but try both ways..

For example, I leave it off when normally using a tripod on static subjects, but turn it on when I'm panning on a bird with the ball head loose. It sometimes seems to help in those cases.Cheers, Craig..

Posted this in the wrong location - disregard.

If the camera is resting completely by itself on a stable platform, e.g. table, etc., I turn it off..

If I'm using a monopod, resting/leaning against something, I turn it on as it will not be 100% motion-free..
