| When doing a long exposure photograph, should you turn off the camera lens' IS feature? |

| I would think off. You need a tripod for night photography so I don't see the IS helping. Just my thought |

| But does it hurt? I'm wondering if it can get confused and slightly blur an image? |

| I very recently purchased my elephant lens - the Canon EF 70-200mm f/2.8L IS USM. The book is very specific about the IS - it says to use it for hand held and for monopods, but that it must be turned OFF when using a tripod. |

As beetle says, IS will over compensate and can result in an oof image.
*edited to say*
IS doesnt mean you hold a long lens for seconds (maybe a couple of stops worth)

I've never thought of this, and don't own any IS lenses so I've never needed to decide. I can't imagine ANY reason to leave it on - it would drain the battery faster than with it off, if nothing else. It's also possible that the little spinning gyros or whatever could introduce some vibration.
So, turn it off.
Damn slow. What ecce and beetle said.

| Turn it off and leave it off forever. Well not forever but almost always. If you are using a tripod always have the IS off. |

I asked because I was trying to do some night photography with a tripod and noticed that some of the pictures were a bit oof. Thanks for the note from the 70-200 manual. I'll have to remember to turn it off the next time I try some night photos.

The 70-200 f/2.8 IS has the latest generation IS mechanism and detects it's on a tripod and switches off automatically...
No reason to leave it on for long exposures on a tripod though. |
