It is an amazing lens. I had two copies of it over the years, used it with the F5, F100, F3 and FM2n. It is sharp at all apertures, wide open there is a tiny bit of glowing depending on light, you will also get some purple fringing on very high contrast areas but that is more an issue with digital. It is still there on film but film makes it look nicer.
I would highly recommend it, it balances well even on the smaller manual bodies and manual focus is very nice too, ok not like an AIS lens but still very good and much better than AFS lenses. The only issue I had was that wide open manual focusing can be a bit tricky, I found myself stopping it down to f/1.8-2 just to be safe which is still a fantastic look and eliminates the slight haze/glow. On the F5 I had no issues using it wide open, it just nailed focus.
Just get it, you'll love it and in the unlikely event you don't you can sell it for no loss. The only reason I sold mine was that I wanted to try a 58/1.4G (which is another amazing lens and is a bit easier to work with indoors due to the shorter focal length).
