Hazy shade of gray
Nikon omits the aperture from their product specifications but "1:3-5.9" is on the barrel in their product views. I have lens that's f/5.6 at 300mm and I don't think this will work. f/5.9 isn't going to produce much sensor illumination for anything that isn't in unfiltered sunlight. The sensor will be running at maximum ISO and that won't produce a clear enough image to compensate for the large amounts of atmospheric haze to be expected at such a high zoom level.
