Autofocus or Manual focus?

Autofocus (AF) - is the function of a camera to automatically focus on a subject. Most general digital cameras have this function. There are various AF methods, and the available methods are different depending on the mode of your camera to use different methods according to the scene or subject you want to photograph.

The following explains the AF methods:

AF-S (Single-shot AF) - Autofocus operates when the shutter button is pressed halfway down. Once the subject is in focus, the focus is locked. It is suitable for photographing motionless subjects such as landscapes or snapshots.

AF-C (Continuous AF) - Auto focus continues to operate and keeps adjusting the focus while the shutter button is pressed and held halfway down. It is suitable for photographing moving subjects such as sports or railway photography.

AF-A (Automatic AF) - When the shutter button is pressed halfway down, the camera automatically recognizes whether the subject is moving or not, and switches the AF mode between AF-S and AF-C accordingly. Use this mode to photograph various subjects at the same time, or to avoid switching the AF mode manually.

Direct Manual Focus (DMF) - You can make fine adjustments manually after performing auto focusing, letting you focus on a subject more quickly than when using manual focus from the beginning. This is convenient in situations such as macro photography.

Manual focus (MF) - Manual focus is the function to let the photographer adjust the focus manually instead of the camera. Although autofocus (AF) shooting is more typical in digital camera, MF is effective when focusing is difficult with autofocu, such as in macro shooting. In MF, you can adjust the focus position by turning the focus ring on the lens.
