Not wanting to put a downer on this great lens, but I just sent mine back to Nikon for repair. Its almost 1 yr old and suffers from lens drop ( like creep but more rapid) and wont focus properly on AF.
BUT, while it was working it was on the camera all the time and produced excellent results.
To overcome the lens creep on many lenses, some people have fitted a rubber O ring or one of those charity bands over the zoom ring. Looks ugly but works.
Of course, yours may be one of the many that doesnt suffer from this, fingers crossed, but, to be honest, the lens is so good, the creep is just a minor annoyance. Cant wait to get it back!
Enjoy yours.
(I leave mine on VR normal all the time)
