This question already has an answer here:
I have a D3200 with 11 focusing points:
The newer and more expensive bodies have even more focus points like e.g. the D610:
I mostly work in Single-point AF mode, which means I choose one of the 11 points, move the one point over my subject, and focus.
Isn't it more comfortable to have fewer focus points wider spread over the whole field instead of like 50 in a small area in the center?
- when I want to focus something in the left corner, there is no focus point and I have to set the focus with a different focus point and move my subject into the position with locked focus
- the more points I have, the more difficult to handle is the Single-point AF mode by switching between all of these points
Am I misunderstanding something about focusing?
Even in Dynamic-area AF mode or 3D-tracking which uses all of my 11 points, it won't be able to focus something in the corner.
