I had the 85/2 a couple years ago shooting it mainly on my D80, D300 and a couple film cameras. I loved the construction and small size particularly. I also found it to be a very sharp lens. The 'but', and the reason I didn't hang onto it was to my eye it did not produce the contrast or 'punch' that I see from my other lenses. Very subjective, take it with a grain of salt.
For $200 it might be worth it to give it a try. I sold mine for $185 if I remember correctly...
When I was first building my kit of MF Nikkor lenses I tried this lens because it is so affordable. I paid a bit over $200 for the lens and was quite pleased with it. I eventually invested in its big brother, the 85 f/1.4 AI-s which is three times as expensive and certainly over twice as large. It is also a great lens. But since size is important to you, my guess is you would be happy with the f/2. The problem Tony refers to with regard to contrast can be easily handled in post processing if you're comfortable doing that kind of work. I've kept my f/2 on the off chance I'd want that focal length in a smaller package, but I find myself turning more often to the classic 105 f/2.5 AI-s when I want a smaller lens. If you're not familiar with that lens, you owe it to yourself to check it out. You should be able to find a copy of that lens in EX condition for around $200 as well. I know of NO ONE who knocks that lens.
Welcome to FM. You should be aware there is a very busy thread in the Nikon forum that is committed entirely to Nikon manual focus lenses mounted on Nikon cameras. A number of participants are shooting with the D800. If you're at all considering other MF lenses, you might want to check out that thread... "Manual Focus Nikon Glass" that is at or near the top of the page most days. Good luck.
I had it for a while and it's a great lens. I also have the Rokinon 85 1.4 and it's one of my favorite lenses particularly for portraits and video. My advice is to save up for the 85 1.8G since you already have a great manual 85, or get the 105 2.5 AIS which is also better and goes for the same price and gives you more options in FL. The 85 1.8G and 105 2.5 are better on all levels and relatively light weight. But that's up to you, and welcome to FM
It's a very good lens, but not as good as the 105/2.5, or the earlier 85/1.8 non-AI. The drawback to the 85/1.8, though, is that it's pretty heavy and bulky, and bokeh when stopped down to f/4 or so is weird and polygonal. For a compact lens that you're likely to use stopped down, the 85/2 is great. For something used more often at wide stops, the 85/1.8 is better.
$200 is probably a reasonable, though not amazing, price.
