IS on 24-105

Hi, this may be a stupid question, I just purchased the 24-105 f4 IS L lens, haven't had time to use it out doors, only indoor shots, very nice!

Anyways, my question is, do you guys turn off the IS switch in daylight when the shutter speed is 1/200 or higher, or do you just leave the IS switch on, thought maybe can save battery drainage with sufficient light, and not ruin the motor if not required, thanks in advance.

With respect to that question, when I use my 70-200 IS, it's like on 99% of the time. I know when there's more daylight less chance for shake, but sometimes when you are running around, your hand slips once in a while, at least in my case, when its a frantic pace, and sometimes my IS has corrected that photo that otherwise would be kinda blurry because of my little bit of shake, even if the shutter was above 1/200.

I never turn off the IS on either of my lenses. Even if my shutter speed is very high the IS helps give me a steady sight picture.

What's the advantage to turning it off? Doesn't seem to draw much power based on my use of the 17-85 IS with my Rebel XT. I feel I bought it, I'm gonna use it.

Hi Canonblade, I always keep it on no matter what the shutterspeed for the very same reasons as Skip.

I did some tests.
Sometimes I thought I am getting better image with IS switched of.
But later I have decided that the reason was something different, not the IS.
I am still not sure...

If I am going to put the heavy lens on the camera, I just keep the IS on or else I'll use another lens. I think the IS can only help. If it shakes too much because of the subject, then try it off. I also keep it on 95% of the time. I shake just holding it.

I only turn IS off if I'm using the lens on a tripod. The 100-400 requires this. Canon says the 70-200 will recognize when it's put on a tripod and shut down the IS, but they still recommend turning it off in that situation.

Me too!
I've made some test with IS on and off and I could not see any differences in image quality. So I keep it always ON in my 70-300DO. And battery life is not an issue, as it lasts for hundreds of shots.
