Hello Dan,
Even though you use a DX body, all the lenses in your profile are FX. Nikon has been making the 80-200mm fixed aperture lenses for a long time. Starting with the pre-AI f4.5 model they are pro quality lenses and can produce pro quality images. The heavy f2.8 models did have their weaknesses though. The earlier AF and AFS 80-200mm f2.8 lenses have excellent resolution but they can suffer from vignetting wide open and lens flare when shooting towards or close to the sun. Nano coating had not been invented yet and they didn't have VR. These issues were mostly corrected in the 2nd version of the AFS 70-200mm f2.8G lens. But the lens was still very heavy and very expensive due to the massive elements required to keep a fixed f2.8 aperture throughout the range. Now enter the new AFS 70-200mm f4 lens. It's much easier and cheaper for a designer to make an f4 lens versus one at f2.8. The lens elements are much smaller and it's easier to design away vignetting and other distortion problems. So I would expect the new f4 lens with it's nano coating, multi ED elements and VR to perform very closely to the latest f2.8 version. Some improvements may be it's wide open performance, it's much lighter weight and certainly it's reduced cost. What it doesn't have is an f2.8 aperture and the tank like build quality of the older 80-200mm lenses. If you stay with a DX body, except for flare, you may not see a difference between the new and the old.
