Question about IS and fast shutter speeds
So, I know the IS in my lens is for low light situations to help steady the image..

And I know that IS is useless for action shots and a moving subject..

Does this basically mean that it's pretty much useless at all fast shutter speeds..

For example, if I'm shooting at 200mm focal length with something like 1/500, 1/800, 1/1000 shutter speed IS is useless correct? It's basically just draining my battery?.

So, for these situations, is it best to turn off IS?..

Yes. That's about the size of it. There's no point in "decreasing" camera shake when there wouldn't have been any..

Yes.Regards,Baz..

The best answer is to try it yourself and see..

Perhaps you still induce some blur at 1/500; take two telephoto pictures at 200 mm, and examine the results.Another issue may be whether your IS requires extra time to focus, etc.Warm regards,DOF..

Wow. Thanks for the quick responses. I kind of was thinking that with those shutter speeds camera shake would basically be non-existant. But, I will try that test that you're suggesting..

I guess my biggest concern was the fact that my fully charged battery seemed to die after about 220 pictures with my new IS lens turned on vs. the usual 800 or so ^^..

Nope, it isnt useless & it can and does make a difference to sharpness, certainly up to around 1/1000Unless you have very steady hands the old 'equivalent' factor (use a shutter speed at least equal to your lens focal length) usually gives adequate but not exceptional sharpness. As for battery drain, thats never seemed much of an issue on my Nikon..

The IS in lens or camera is ment to reduce the blur thatis caused by the "holder" not the "subject".It is still useful at hi shutter speeds.I use mine for all shots except Tripod type....
