Nikon D5200 Custom Setting Menu
I normally suggest KR's custom setup guides to beginners. But, here's an example of a dumb-as-a-pile-of-dung comment he makes RE "
AF-C priority selection top
By default, the FOCUS selection ensures that all your pictures will be in focus in
AF-C mode. If the subject is moving a lot, the D5200 may run a bit slower as it tries to focus properly for each frame.
If you'd prefer the D5200 to run full-speed, even if it's not in focus, choose RELEASE instead. I never use this;
why would I want out-of-focus pictures?"
Okay, this is one I have to disagree on...I set my cameras to Release priority because there are many thousands and thousands and thousands of photos I will take in which I want the moment captured when I say FIRE! and press the release. And frankly, I am surprised Ken has not though that one through, because many times the depth of field will ensure adequate focus on a subject that might happen to be a little bit OOF according to the AF system's computer brain. On moving subjects, especially fast-moving ones, it is in actual fact necessary to have the focus plane a slight bit IN FRONT OF the subject, so that by the time the mirror moves up and out of the way and the shutter makes the exposure, the
subject arrives at the focus point. With a short lens, having absolutely precisely dead-on focus is NOT absolutely 100% necessary if the aperture is at f/5.6 or smaller, like say f/8 or whatever, at distances of beyond about 15 feet on a crop-body camera.
In AF-C, which is the mode I use 99.9% of the time, I do NOT want the camera's brain determining when I can fire. Ever. Never, ever,ever. If it's not in proper focus, who gives a sh*+...there's no film cost. If you get an OOF frame, it's not like it's 77 cents a click, like it used to be. When the camera is set to Continuous AF, the main priority ought to be RELEASE. My God.
In AF-S, then the priority is focusing. But in AF-C, the main criteria is to keep the camera firing, continuously. The depth of field "cushion" at f/4 and f/5.6 will cover your butt on slight mis-focus, even with a 300mm lens at 40 to 200 feet. With something like an 18-55, focus is not all that critical beyond 15 feet.
