Re: Autofocus for D90

I admit that I am not a BIF shooter. But as a 7DII owner, I've read and viewed a lot of comparisons between the 7DII and 90D AF systems, and one thing that has seemed to be a consistent advantage for the 7DII AF system (aside from dual processors) is the larger number of AF points (45 vs 65) for tracking. Based upon that, it would counterintuitive to choose a smaller number of active AF points for a fast-moving subject. You mentioned that you followed the guidance of an experienced bird photographer. Did they specify using fewer AF points? I understand that the 7DII is one of his main bodies, specifically for the AF system. It seems odd that he would intentionally cripple one of its very advantages.

Also, I have heard reports of iTR settings affecting AF accuracy. However, it may not apply in your case if it is automatically disabled if fewer AF points are selected. Just something to double-check on.
