IS lenses effect on video?

Do IS lenses have any effect on video? Or is the IS strictly a still photo thing? If there is an effect, is it good or bad?

Yes they do. They help stabilise the image if hand held.

However, hand holding is a bad idea and should be avoided when ever possible as, even with IS, it looks awful. It can make footage from a shoulder rig bearable though.

IS makes a noise and can be picked up by on camera mics (another bad thing which should be avoided).

IS can give a rolling effect during a pan, moving beyond the stop and then pulling back.

John, I really appreciate all your responses on this forum, you've been a big help. Is it safe to assume then that IS would not work well when flying a camera on a Glidecam? Sounds like there might be some benefit to completely stationary shots but it might hinder anything on a slider or Glidecam.

I think the exact opposite it true. IS works great, I use it on monopods, when I had hold, or when using steadicams. The only time I prefer not to have is is when tripoding shots.

In my opinion IS no help at all in the video.

What does this mean, exactly? Does it mean that while shooting video with sound, you will hear some odd sound on playback? Is it the actual lens that makes a sound?

Yes, the lens makes a sound.

+1, :Using IS with monopods creates a very steady image, even with telephoto shots.

I didn't say IS isn't any good for video and, if you can't use a tripod for what ever reason, it certainly helps.

My point was, any situation when you don't use a tripod is likely to compromise the shot, IS might make it less of a compromise, but still not as good as a tripod.

Been shooting video professionally with DSLR's since the 5D mkII was released.
IS does work for video BUT there are caveats that everyone should know about.
Just like IS on a video camera, it will fight itself if mounted to a tripod or slider and left on.
Steadicam it's OK to leave on. Monopod or shoulder rig or handheld it's fine too.
The sound only becomes an issue if you have a mic mounted to the DSLR or to the rig. Getting the mic away from the camera is highly recommended if you want good sound anyway.
Personally I don't use the IS for anything. I typically shoot with a 70-200 f2.8L USMII, 24-70 f2.8 USMII or a Zeiss 21. I am a Steadicam operator and have a shoulder rig, tripods and crane too. I have gone "native" a few times with pure handheld and the IS did make a difference but I wanted shaky, handheld look to the video anyway so I turned it off!

Oh, and rolling shutter has nothing to do with IS. it's a function of the CMOS and can't be avoided even on cameras like Red and Arri. Fast panning is a no-no with any CMOS camera. Sony's F-55 is going to change that with a global shutter but at the price of a really nice luxury car! The effect of leaving IS on during a tripod pan is the fighting I mention above and will show as jittery, skipping video.
