Re: Deference between VR and Non VR lens. VR stands for vibration reduction and is what Nikon calls it's version of optical image stabilization. Image stabilization basically counters the camera shake you get from holding the camera, making it so you can use slightly faster shutter speeds than without it. Non-VR lenses do not have this feature, but cost less than VR lenses.
