I've got one of these and it is superb using it on a Nikon 80-200, 70-200 and even the 80-400 zooms to use in the field in place of a real macro lens. More convenient than a macro since the zoom is useable, except beyond just a few feet, and the the 2.8 of the 70/80-200 lenses, great subject isolation! This lens can't be beat!
