Ask about the focusing method of Nikon D300S.

This thing is quite confusing. Let me say it briefly. First, s, c, m, s means to press the shutter once and focus only once. After the focus is completed, there will be a drip prompt, just like a home card. It is suitable for daily photography and still life photography, but if the subject moves after focusing but before pressing the shutter, the focus will stay in the original place and there will be unclear situations. For example, use it when shooting athletes running towards you.

At this time, mode C appeared. When you press the shutter halfway, C starts focusing until you release the shutter. At this time, when the photographer runs towards you, you will find that the first picture is clear when using continuous shooting, and the camera always changes the focal length with the movement of the object.

But sometimes, when autofocus also fails, as an emergency measure, you can turn off M and adjust it manually. As an entry-level user, you won't need this.

Let's talk about automatic area autofocus, dynamic area autofocus and single point autofocus. Automatic area autofocus is to let the camera analyze the picture and automatically decide who is the subject and the focus position. For beginners, daily use is very convenient. You can just press the shutter at the right angle like a card machine.

Dynamic area autofocus and single-point autofocus are aimed at professional users. In dynamic area autofocus, you can choose a center to focus, and the camera makes intelligent judgment near that call point, which is equivalent to roughly pointing out the direction of the subject and the camera goes out of focus. Single-point autofocus has clear focusing requirements. Command the camera to focus according to your meaning. These two kinds of household appliances are not commonly used.

I remember I answered a similar question to you once, and I will leave a message after confirming the best answer.
