What is phase detection AF points?
With phase detection autofocus, think a bit of the moon and its various phases. For the camera, when a specific point finds itself being in perfect focus, there are light rays. A photograph that is in focus will have light rays that will cast a light on the opposite sides of the lens.
What is phase detect autofocus?

Is 9 AF points enough?
Some cameras have only 9 autofocus points while others have well over 1000. Is that something that will make a big difference in how you take photos?

Which is better phase detection vs contrast detection?
Contrast detection autofocus is smaller, less expensive, and more accurate – at least, on still subjects – than phase detection AF. But it’s also significantly slower. It takes time for a contrast detection system to calibrate, which means it’s not ideal for fast-moving subjects.
What is AF Area Auto clear?

Do photographers use autofocus?
Most photographers use autofocus more often than manual focus. The main reason is simply convenience; it’s easier than focusing manually. Autofocus also tends to be faster, and, in many cases, it’s also more accurate (such as tracking focus on a moving subject).
