Sigma 150-600C + 5D4 + 1.4x at F9 AF.
I have this lens on 5d4 with a Canon 1.4x extender mark ii, and I can use the center column 7 points at F/9. I am wondering whether I can get more points with a mark iii, or a Sigma converter. Anyone have the combo please chime in. Buy another converter is not a big deal really.
