I can't help but make a comment about the Nikkor 105mm f/2.8 I realize that most folks just love the lens but there are some bad copies out there. I bought one a couple of years ago and it had more longitudinal chromatic distortion wide open than any lens I have ever seen. Everything in front of the focus point was very purple and everything behind was slightly green. I immediately sent it back to Nikon who did nothing but adjust the focus setting and sent it back. I then called someone I trust at NPS who told me this was not that unusual for this lens but mine was on the extreme edge and Nikon wouldn't do anything about it. I asked how these lenses are successfully used in portrait work wide open. I was reminded that most portraits have nothing in the image that is closer than the focus point so the lens works.
I kept the lens for another year or so but it annoyed me so much every time I used it that I sold it at a loss and went back to my old 105mm AIS that works flawlessly.
Sorry about the rant but I do feel just a little better now.
