I've seen this alluded to in passing and also stated plainly as a fact. But I have not seen anything to suggest this, besides what has been said.
Does VR really affect image quality? That is, if camera shake is not an issue, does switching off VR improve image quality?
Does a VR lens with VR switched off produce the same quality image as a non-VR equivalent lens (maybe this would only be a theoretical test)?
Obviously, at alower shutter speeds (relative to focal length), VR will improve image quality by stabilising the image for the duration of the exposure if the lens (or, more particularly, the sensor) moves relative to the subject. My question is really about whether or not VR degrades an image, with all other factors being equal. I think you know what I mean. Excuse me: I'm not a rocket scientist. I just make pictures.
