relevance of image stabilization to videography with DSLR

Liam, what do you find most useful about the 70-200? Quite a large lens – I imagine it’s on a tripod or monopod, mostly, anyway, right?

another aspect to IS: On Philip Bloom’s web page about lens selection, he states that IS helps with reducing rolling shutter artifacts.”

The 70-200 f/2.8L IS MkII is very sharp and has excellent bokeh. It really is a superb lens, brilliant for interviews where you want to blur the background. For stills it has a quick and accurate autofocus.

It is large and heavy compared to f/4 lenses, so yes it’s always on a tripod or monopod.

Can’t say it reduces rolling shutter artefacts though, that’s a feature of the write speed of the sensor and has nothing to with the lens.

2012 and Canon has PL-mount cine lenses, but STILL no IS for the 24-70mm f2.8 L. Sigh…

Liam, I picked up a used 24-105mm Canon and noticed immediately, in Movie mode, that the IS is quite audible (in a quiet room, and within a couple feet of the camera). Is this common or did I buy a bad lens?

Bob, I have a new 24-105 bought 2 months ago and have not noticed a problem with noise from the IS.

Yes, it’s common. Even if you get one that is silent after a gentle knock or two it might start getting noisy. Certainly, some lenses are more susceptible to noise than others.

I have 3 zoom lenses for my 7D, 2 IS, love them! Looking to add a 4th zoom, will be IS. Most of my shooting with the 7d is handheld video and stills, I use the feature for both and love it.

Hello all, I use a 5D and a 60D, with 70-200 f4 & 2.8, and the EF-S 17-55 f2.8, all with IS. I find IS crucial to handheld and also use it while on sticks. I never turn IS off, unless I’m doing certain pans; have found that I see the IS working through the pan and it detracts from the camera move, but on most pans the IS does not exert a negative effect.

I have had an issue with the noise from the Image Stabilizer being picked up by a Rode Video Mic, and that’s why I’m posting here. I had a shoot with tons of audio issues, and found myself having to use several shots from the on-camera mic, where the IS gurgles and has been tough to remove. Does anyone have experience and luck with removing the IS noise in FCP or X-crackle in Pro-Tools? Searching for a plug-in but can’t find one.

Thanks very much

Hi Sam,
I’ve had some luck using Soundtrack Pro’s noise reduction feature. As long as you have some audio with just the IS sound and no other noise it should work.

Good luck,
Drew

“Gurgle” is a good description.

Good to know that STP will get rid of it, but I’d advise turning off IS when you have a critical audio situation. I shoot mostly with a regular video camera, and there are enough audio challenges in the environment without adding another.

I agree about the greatness of IS, though.
