Autofocus AF-S Accuracy: Nikon 85/1.4G (Trash Can)

Previous pages shows both accurate and inaccurate results.

This test uses a dark but high contrast target which to my eye is completely unambigous. AF-S mod with AF-S priority selection = Focus and AF Fine Tune = 0. Also, I verified that the position of the focus sensor as indicated by the camera in the viewfinder is actually accurate (using the edge of walls and similar targets).

A Live View frame was taken as a reference.

The test scene and autofocus sensor position are shown below, captured by the Nikon AF-S 85mm f/1.4G.
