In researching vibration reduction, (VR,VC,IS, whatever the lens calls it) I have read a lot of articles that have compared the same lens, but VR -vs- non-VR and have found mixed results. I dont know if it is just a matter of taste, or if there is some validity to the claims that the non-VR lenses take a sharper picture than the same lens with VR. I have lenses with and without VR, but not of the same model or focal range to compare them myself. If anyone has been able to do the actual side by side comparison of the same lens with and without VR I would love to hear their opinion on it. When I purchased the faster zoom lenses, I opted for the non-VR versions partly because of price, and partly because I had been shooting with prime lenses mostly and been doing fine without VR. I know there are obvious advantages to VR to help with hand shake, and especially when you have longer shutter times, but are there any advantages to having the non-VR lenses or is it something to save up for and replace non-vr lenses with?
