bo tak podaje instrukcja nikona D5 i trudno z nią polemizować
Hogan wyjaśnia to tak:
"Why the limitations? Well, Nikon is pushing the D5 (and D500) focus system right up against some physical limits. Phase detect is angular sensitive. Restrict the angles at which the data is being obtained and you begin to make the system less accurate or eventually inoperative. Smaller apertures mean less angular differentiation"
