Just a comment about IS (and not specifically directed towards you or anyone) -

Some say that at higher shutter speeds IS is unnecessary or even undesirable. But regardless of shutter speed, IS stabilizes the image which both the metering and the AF have to work with. At any kind of zoom focal length it is near impossible to hold a camera totally still and with only the tiniest edges of foliage etc. for the autofocus to work with, having the image jittering has to make it very difficult to attain focus. I would say that regardless of shutter speed, at zoomed focal lengths, it is beneficial or even important to leave the IS turned on.

One other comment, about sharpening - an image which is not properly focused cannot be saved by sharpening any more than burned food can be saved by mixing some uncooked food into it. A blurred image with more than the very tiniest bit of sharpening applied gets even uglier.

Do people really spend $700 on a camera so they can take a picture of a duck?
