IS and tripods

[John Jarosz]

I just noticed that the instruction book for my E-P1 says to turn off the IS when the camera is on a tripod. I can't understand why turning the IS off is a benefit. Can anyone explain?

Thanks

John

The IS makes a very slight vibration and that will transfer to the tripod.
The tripod is your IS.... Right?
Maybe Peter will offer a better reason.
He's using a tripod for much of his work.

As I understand it, most IS systems assume that the camera will move/shake. When you use a tripod, movement/shake is eliminated. This confuses the system and renders the IS function ineffective. I really notice it when I use my Canon 50D with IS lenses on a tripod. I'd love to know why. Maybe someone could explain the technical reasons.
