Nikkor 800mm f12 piggy backed on 4x5 with 50r

Following shot from a distance of 400 feet. Aperture f16.  The image is uncropped.  Thought you might want to see how the sharpness compares to the Pentax 600 posted earlier.  400 feet is also the minimal focusing distance, which is really wild. The bellows with extension tube from sensor plane to the from element of the lens is 21 inches.

Takes a few seconds for the set up to settle down from vibrations. Your thoughts on the quality?  Perhaps Jim K can tell us the effective focal length. Thank  you.

400 ft. f 16, uncropped. smart sharpening applied.
