Nikkor 105mm f/2.8G ED IF AF-S VR
Its a great lens and I use it for portraits regularly. Short and to the point.
It is a very nice, very flexible lens. Don't use it for portraits, but if the focal length works for you then it should be fine. I use it primarily as a macro (imagine that) and a short tele. Optically, it's not quite in the same league as the 200 f/4 but it's half the weight, faster focusing and has VR.
I break things.
