The camera that I use is the canon t6, it is a bit older but its been really great to me so far. The canon t6 has a total of nine auto focus points.
The canon t6 only has a single cross type af point at a specific f/stop which is 5.6. The other 8 af points are single axis. The best f/stop would have to be 5.6 for the greatest performance.
