Has anyone had experience with the new Nikon 18-200 VR DX lens with extension tubes? I'm interested in doing some macro photography and I know that some lenses perform better than others with extension tubes. I don't own the lens currently but I'm considering a future purchase. I own the Kenko DG extension tube set with my Nikon D100 camera and 24-120 VR lens.
Thanks for your help in advance!
