Nikon vr1 70-200 ? I have one, don't think of putting it on anything high resolution, the edges ............ frightful! The VRll is pretty good, still over hyped with its optical performance, mine went back a couple of times before it was satisfactory. That's on D800's I have 3 of them I have had the tammy for a few weeks, its a good lens and not just satisfactory and some comments here are questioning it being a match for the Nikon variant? I would say : be afraid Nikon, be very afraid there is a Titan that delivers and it ain't got Nikon stamped on it!
