While I do not own a 150Nikkor, I do own a 210 Nikkor W, and I have found that does not perform well for close-up work. I was told once that the Nikkor W's are not symmetrical and therefore do not perform well at close distances....(I have no direct knowledge of this as I am not really interested in optical design; I realize that it surely may be possible that he didn't know what he was talking about) but, as mentioned earlier, I would have to agree with his assessment, at least in regard to the 210W. I do have a Rodenstock 150 N, which I use for virtually all my close-up work, and find it to be marvelous.
