Wondered, why VR (Vibration Reduction) had different names and were little, confused when I saw that there were different names on different brands. so I googled a bit and found this!
Same technology, different brand names.
Pretty much the same technology under different acronyms.....probably due to trademark infringement
VR (vibration reduction) is Nikon's trademark name for stabilization. Canon's is IS or "Image Stabilizer. Same thing from different brands.
