I've got the AF 85/1.8, which is completely different, but I love this focal length. The 85/2 is considered to be the least desirable of Nikon's 85s, but I've read more than a couple of owner reviews of the lens and I get the impression that the /2 is underrated.

A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and two crappy 4x5 cameras with very good lenses (a better camera is on the list).
I have an 85mm f2.0 AI version of this lens. It is often overlooked by those wishing to get the much larger and heavier f1.4 version, and I think that lens is why the f2.0 has been so looked down upon. Perhaps there was poor quality control at some point, but the example I got is quite good. The defocus and wide open are not as good as the 105mm f2.5, but that lens is nearly legendary from Nikon. One thing I think very important on the 85mm f2.0 is to use the lens hood, since this lens can be very prone to flare from light striking the surface of the front element directly. Use the lens hood always, and no worries.
I've got an AI 105 f/2.5 too, and yes that lens is absolutely spectacular. But I find that focal length a little bit too long for my liking and it doesn't see nearly as much use as the 85. I don't understand what the gripe about the 85 f/2 lens is. I mainly use mine between f/4 and f/8, and at these apertures it's a hard one to beat.
Yeah, I really think this lens is kinda under-rated. In comparison with my H.C. 1.8, MF 1.4 and AF 1.8, at 5.6-11 they are all pretty interchangeable in terms of sharpness. At f2 and 2.8 the 85mm f2 holds up quite well, yes, not as good as the 1.4 or the AF but not by much. In fact the influence of a slight veiling flare (wide open to 1/2 stops down) looks quite nice in some portraits, quite handy on the ladies of a certain era, if you know what I mean. My version of the 85mm f2 is the Ai, and I really wish I had the Ais, the long-----> throw makes it slow handling, the 1.4 is quicker (even the 1.8) in fast moving situations.
