Turning off IS
May 21, 2012 21:05:26 #
I read recently that, when shooting action sports, that it's best to turn off the image stabilization as it adds to the focus time.
Is this true?
Thanks,
Bill

No, but maybe when the shutter speed is 1/250 or higher. Holding the image still on the focus sensor helps focus. It uses more battery though.

I don't know about adding to the focus time but I've been studying everything I can about my new 7D. Last night I was reading Ken Rockwell's stuff. He suggests that at high shutter speeds, IS should be turned off. He said that IS is more for camera shake. Swamp Gator suggested this to me also last week.

Thanks, MollyMolly,
I suspect you're right and that IS is for stationary hand-held shots.

Nikon VR instructions says to hold shutter release halfway down until subject is stationary then finish pushing shutter rest of way down. Not good for action sports? My sigma lens instruction says the same thing.

I have talked to many about the IS on my Canon 70-300. The use and don't use are mixed but this is what I have found. for horizontal panning use IS 1. For vertical use IS 2. IS works well on a tripod unless you have the mirror locked up and then it is not necessary.
This is for what is it worth but I recommend go out and very carefully document, with several pics of each type and make your own decision.
Good shooting.

Thanks. You would think the manuals would be a bit more definitive on this subject.

What kind of camera do you have. Some manufacturer's build IS in the body and some in the lens. I have a canon T2i and know that canon has it built into their lens.

I have a Canon 60D with the 70-300mm IS USM 4-5.6 lens. It has a switch for Stabilizer 1 & 2. I have been very happy with the lens and have taken about 8,000 pics since I purchased the camera 3-27-12. My other lens is the 18-135mm IS 3.5-5.6. Both have preformed very well but wish the 300 were longer.

I am using a 70-200 Canon F2.8 now with IS built into the lens, but intend to get a Sony NEX-7 which has the IS built into the body, so I am, therefore, doubly confused.
Thanks for your insight.

It is not that it slows focus, but that there is a delay before the stabilization does its thing (on my 70-200 seems like right around one second. In that short delay, the magic is moving stuff inside the lens and you may actually get a blurry image. If you are shooting sports at 1/250 or faster, VR is of little value anyway.

When I shoot Birds In Flight I find that IS does delay AF and my experience is that it causes the lens to hunt more than without IS. It is more apparent with my 100-400 zoom than with the 500mm prime lens. Since I shoot at 1/2000 sec, IS is superfluous anyway. Besides, with fast moving birds, subject motion is of great concern and IS does nothing to help that. Even at 1/2000, sometime birds wing tips are blurred.

I have been reading lots of "stuff" on here regarding IS. what I have gleaned is IS is made for helping with and eliminating blur from camera shake caused by the user -ME - over 70 and shaky-
no need for IS when on a tripod and for sure at high shutter speed so in short - turn it off when not needed - some have said IS messes with long/high mm shots - I for one am going to experiment with that soon.
