There are many Nikkor 300mm versions - all but some samples

of the first tend to be quite sharp to the corners wide open

(which is how I would test it, with a distant detailed

subject [like a horizon line] run along the edge of the frames,

top then bottom, then diagonally both directions). For more,

see: www.David-Ruether-Photography.com/slemn.html. BTW, if

your camera is AI, be sure the lens is, also, before

mounting it...
