OIS when not needed...
1

I've heard the theory that OIS can degrade image sharpness at higher shutter speeds, but never saw evidence of this problem, until today. I shot a photo of a new garden in my yard with my 10-24 with OIS on and, when I looked at the image at 1:1, I was appalled! I went back to the garden and reshot the photo with and without OIS, and the difference is startling. I did two pairs of exposures and the results were the same.

These are approximately 1:1 crops, the exposure was 1/200 @ f6.3, at 10mm. The question is, what is the shutter speed above which the IOS becomes a detriment? I guess some testing is in order (I hate testing)...
