Some people whose photographic opinion I trust feel VR decreases the sharpness of a lens. The added elements to move the image degrades the potential sharpness.

My evaluation, as an engineer, is that VR is a servo and there is always a basic noise level in a servo loop. The noise can dither the image in some conditions.

Even if that decrease could be demonstrated on a print, I would trade that bit of compromise for the increased % of shots that are in focus. Bumping up iso increases noise, so pick your poison. Tripods can be a pain and prohibited in many museums. Try taking a shot of the Declaration of Independence inside the National Archives. No flash, no pods. You're looking at iso 4000-6400, F2.8, 1/30s or less in there. I prefer to own a few zooms rather than a dozen primes, so don't have those 1.8 lenses.

In my less than perfect hands, VR allows a greater % of sharp shots.
