During the past six months, I've done a lot of wildlife photography with a 200mm f/2.8, and I've relied on IS for all of it, because I've shot everyhing hand-held and I was so pleased with early results during low-light conditions. I guess I figured if it was good for low light, it was good for brighter conditions and faster shutter speeds as well.
Lately, however, I've been experimenting with a monopod for the same shots, with the IS off, and I have noticed a slight increase in image sharpness, even at shutter speeds of 1/500.
I've had the same experience with my FZ7K's MEGA O.I.S., which I believe is in-lens technology.
