Nikon VR and VR II come with certain features, which means there are certain similarities between the two. For instance, the vibration reduction technology in the two and the image-stabilization technology in the two are the reason they share certain similarities.
However, since VR ll is the newer of the two, it comes with more enhanced features, and this is what forms the little differences between Nikon VR and VR ll. It is obvious that Nikon is doing everything towards enhancing and improving its lens, which is why there is a sharp difference in the image quality of the two cameras.
What this means is that the quality of images produced by VR ll is more enhanced compared to VR. Another difference is that the image stabilization technology in VR ll makes VR ll a great deal. Unlike VR that compensates for three stops, this goes up to four stops in VR ll.
