Image stabilization in video mode on 7d, 5d, etc?

[simm]

Does anyone know if IS works while shooting video with a DSLR - mainly the 7d or 5d mkii? I couldn't find any info for the life of me.

I think it's all in the lens, assuming you have a lens that does IS. The Pentax K-x does the IS by shifting the sensor to accommodate shake. Someone correct me if i'm wrong.

Right, yeah, it's all in the lens - but does it stay active while shooting? I think there are a couple of DSLR's that stabilize in-camera.

But to clarify: Does the lens keep IS active after starting record?

[spideralex90]

I'm actually not sure if it does while shooting.

I believe the answer is yes, yes it does. But I have just heard this information second hand, no personal experience.

Yes, in-lens IS does work on the 5DMII during video. It seems to help quite a bit for anything handheld, but it also makes a lot of noise that is picked up by the camera's mic.

Here's an example

Thanks, Jwymon. I wonder if IS works on ALL lenses in video mode..

No, only IS lenses.

Dylan - I'm sorry. I don't think I made myself clear. I meant I wonder if all Image Stabilization lenses work full-time during video mode.

Haha, the only [fake] "IS" you get with a non-IS lens is a tripod or a real steady hand. :hv20-smilie55:

Yes, all canon IS lenses do and there are many tests on Vimeo with the EF-S 17-55 and L 70-200.
This is an older thread on the topic: http://hv20.com/showthread.php?t=29730
I never heard of a "few seconds" limit of OIS and I don't see why that should be the case. It would mean that even when you want to take a picture you have to shoot within the first few seconds otherwise the IS stops working.
You can also check this out on Vimeo November - Testing the Canon 7D on Vimeo . In the comments the author says that he had the IS on all the time.
Actually you can hear the OIS working even while just holding the camera with the lens cap on.
I am waiting to get a Tamron VC 17-50 to test that one as well but I expect that to work just as the canon IS lenses.

yes indeed IS lenses stabilise video shooting in a continuous manner.
despite the noisy mechanism, i'd recommend putting IS on when shooting handheld anything beyond 70mm : it does a good job at minimising micro-shakes even with good support.
