New Camera Anatomy: 12 key camera settings to get you started right
8. Focus: Auto
There are two main focusing options, automatic and manual. In manual mode you have to rotate the lens’ focusing ring to get the subject sharp.
In automatic focusing mode the camera will do the work for you. It will focus on the point under the selected autofocus (AF) point.
You may notice that there are usually two or three autofocus options options Single AF, continuous AF and Automatic AF mode. When Continuous AF mode is selected the camera will drive the lens focus mechanism as long as you hold the shutter release button down.
Many cameras also have an Auto AF mode in which it uses Single AF until it detects that the subject is moving and then switches to continuous AF mode.
In most situations you want to use Single AF mode so the lens focuses at one point and doesn’t change if you move the camera to recompose the image.
By default most cameras automatically set the AF point (where it’s going to focus) for you. It’s a useful option, but the camera often assumes the nearest object is your main subject.
In many cases its best to select a single focusing point that can be placed over the subject and used for more precise control. Look for a single point AF mode.
