Dale -- Darned right it will! Consider that it is a superb lens on an FX-format body, and on your D300 you will be using only the sharpest, center portion of the image. And believe me -- it's awfully good out to the edge of an FX sensor too.
Hi, I've been using that combination, with and without a TC-14E11 tele-converter for the past 3 years, and is as good as it gets with this type lens, IMHO. My wife and I shoot horse shows 9 months of the year, we've used the Nikkor 80-200 f2.8, AFS 80-200 F2.8, Sigma 70-200 f2.8 in the past. For all practical purposes we can shoot at any aperture, in any light and the images are perfect. You can see images shot with this combination at suzannefischer.com. ................Remenber, a monkey in a silk suit, is still a monkey. Regards B.
The 70-200 is an exceptional lens on any body. The f/2.8 version was my most-used lens on my D2x, D300 and D300s. These days for walk-around and travel use I tend to carry a 24-120 or 70-300 to save weight, but the 70-200 is still my go-to lens for shooting off-Broadway theatre and other low light stuff.

Both versions of the 70-200mm are optically excellent and will provide outstanding image Quality regardless of format (DX or FX). I have used my 70-200mm lenses on film bodies, DX bodies, and FX bodies and have never been disappointed.
