I have one and use it on my F2 quite a bit. I've had it many years now and it always performs well. As DutchNikon states, there is a neat little pull-out lens hood built in. My copy requires a little bit more effort to focus than some of my other lenses, but not a problem.
I also have the 85 f/1.4, but I think the 105 gets more use. The close focus field of view is about the same for both lenses, but you are standing back almost a foot more for the 105. Overall, there is something a little "better" about the 85: it's smaller, it's faster, and it focuses more smoothly, but the 105 has always gotten more use just because it seems to fit my needs. My most used lens is the 55 mm f/2.8 micro-nikkor.
I was going to sell the 85 to help finance the D800, but since the price came in lower than expected I'm delighted to be able to keep them both. This lens, my 55mm, and my really old, battered 35 f/1.4 are the reasons I never bought a DX body and why I am looking forward to the D800.
