Hey, do any of you really know anything about this lens? If it were a DX lens, it would be a top optic! Image quality is superb, of a quality that you can get only with Nikon's pro lenses, none of which are cheap. But, according to your statements, you wouldn't buy one of them either. This is a top notch lens and, yes, I use it and love it. Just expounded on something based on seeing its introduction and knowing nothing about it, does not contribute anything of value. I was hoping for more knowledgeable feedback in this forum.
