Well, the 50.1.4 Ai-S is still a decent 50mm lens. See this test:

It's fine. The 80-200/2.8 AF-S is the most recent lens I have bought. It has good handling, and the focus lock buttons on the barrel, at the mid-point of the barrel,make this the best Nikon lens ever made for portraiture where you want to focus, and re-compose and lock the focus point when shooting TALLS. It focuses fast; maybe not as fast as the 70-200 VR, but still, quite fast. It has an aperture ring on the lens, which is handy for video. A 50 1.4 Ai-S plus a clean 80-200 AF-S is worth $1,000, yes. The 80-200 AF-S has FIVE ED glass elements, and is a better lens wide-open than the two-ring, much cheaper, much more-common AF-D model. It has better, more-expensive optics, and always retailed for much more money.
If you plan on shooting at f/4 or f/5.6 or whatever, the 80-200 AF-D "two-ring" lens is okay, but the focus will be whiny. If you want a higher-grade lens though, the 80-200 AF-S is a fgood lens on FX Nikon. The 70-200 VR lens handles GREAT, but is not very good on FX 24MP: the corners are poor on it on FX. Modern, high-MP d-slr cameras., especially FX format bodies, are starting to show the issues some of the older lenses have.
I had a couple older 80-200/2.8 ONE-ring zooms. Doggy. Loud, slow focusing. PLENTY of uncorrected color fringing at the longer end. LOTS of light fall-off. Not nearly good enough for modern high MP cameras. Very light though-15 oz lighter than other 80-200 Nikkors. Approaching 30 year old design, and mechanically a lot of these things are like a beat-to-**** old farm truck. Mechanically very clunky, kludgy.
Read the Thom Hogan 80-200 2.8 AF-D lens review, and pay careful attention to what he says; as he notes now, we are no longer in the 6-megapixel d-slr era, and a lot of lenses that are fine on low-rez, older cameras can no longer cut the mustard, especially at f/2.8. If you are at 24- or 36-MP now, do not sink money into stuff that ONCE was good, but now is not good enough.
THE REAL SLEEPER is actually the new 70-200 f/4 AF-S VR-G; now there is a modern, affordable lens, one of the best zooms on the market. Yes, it's f/4 but it's far better than anything older at f/4.
