The 300 mm f 2.8 is compatible with the TC 16A according to Nikon so you are ok in that regard. It will focus to 8.5 feet. You will have the effect of closer focusing in any case because the TC 16A will magnify the center of the lens image by 1.6 times. I wish I had a 300 mm f 2.8 to experiment with but my pockets aren't deep enough to add this piece of gear. Try it and let us know what happens. Best, John Wall -- John N.
