  • \$\begingroup\$ Unless something has changed recently, Nikon has historically been very closed-lipped about the exact specifications of their AF systems. Unlike Canon, who publish comprehensive guides about theirs, Nikon seems to treat that information like state secrets. Good luck. \$\endgroup\$

According to Nikon D750 User’s Manual (rev. 03), there are 11 to 15 autofocus points rated up to f/8. On page 430, the manual details which points work with different lens and teleconverter combinations.

The 15 points that usually work at f/8 comprise the 3×3 square around the center point, a row of 3 points to the right of the square’s middle right point and a row of 3 points to the left of the square’s middle left point.

The 11 points that always work at f/8 are the center point, a row of 4 points to the right of the center point and a row of 4 points to the left of the center point, the point directly above the center point and the point directly below the center point.

Nikon D750 User’s Manual rev. 03, page 430

The TC-14E series of teleconverters lose about 1 stop of light, the TC-17E II loses about 1.5 stops, and the TC-20E series lose about 2 stops.
