Am i right in thinking that the new 70-200 f4 IS can be left with the IS turned on when on a tripod? I know the ealier zooms needed to be turned off but from memory the new ones can be left on?

Thanks

Dave

Yep, according to Canon anyway... There were some reports of people who saw a decline in sharpness when leaving the IS on while using tripod.

It's supposed to be OK but I turn it off anyways. Then there is the remembering to turn it back on thing.

I learned the hard way with the 300 F4L IS. It's not one that's OK on a tripod. If I half press I can see the view shift.

Yes. It senses the tripod.

The little switch isn't that hard to move

Like others said it is supposed to be o.k. to leave it on, but I have found that every once in a while I would get a shot that looked a little blurry. Now I turn it off every time and I haven't seen a blurry shot since doing so. I would recommend flipping the switch just to be safe. That is what I do.

How does it sense the tripod and what does this mean? Does it turn off when it sees no motion? I just tried it out with my 70-200 F4 IS and when mounted on the tripod, everytime I press the shutter button part way, the IS engages and does it's thing. I don't see how it differs any on a tripod.

Thanks guys.

Yeh! I hear the IS kick in on my tripod and that`s what prompted me to ask.

I would suggest you turn it off under stable tripod conditions, but with the wind blowing or surface vibrating, leave it on.

Supposedly yes, but I've always turned off IS on tripods. If you have a good tripod, it would be redundant at least to use IS, if not an unnecessary use of battery power
