| p.1 #7 · p.1 #7 · Question about the effectiveness of IS at higher shutter speeds |
There are so many variables here it is not even funny! It depends on the specific lens, the generation of IS, the camera, your technique, etc. I do know the IS takes a split second to "spin up" and do its thing. My experience with my V2 70-200 2.8 is that the AF is faster than the IS, so having IS on at faster shutter speeds (for me , above about 1/200) adds nothing. I would imagine if the IS is "jumping" and not settled yet, it could actually negatively affect the image just like excessive camera movement would.
Now my 300 2.8 does not focus as fast, but it is a non-IS. I shoot it almost exclusively on a monopod so far, and at shutter speeds 1/500 and above. Absolutely brilliant results! I do not miss IS one bit so far. Of course, YMMV...
