What is the autofocus type in Nikon D3300, Is it phase detection or contrast detection ? Or both ? If both then when is phase detection used and when is contrast detection used ?
I was looking in the below link of the technical specifications of Nikon D3300, there are 2 specifications related to Autofocus
Nikon Multi-CAM 1000 autofocus sensor module with TTL phase detection, 11 focus points (including one cross-type sensor), and AF-assist illuminator (range approx. 0.5-3 m/1 ft 8 in.-9 ft 10 in.)
And the other spec is
Contrast-detect AF anywhere in frame (camera selects focus point automatically when face-priority AF or subject-tracking AF is selected)
