Why it matters.

Choose where and when the camera should look for sharpness.

A closer look.

Focus mode determines how focusing behaves over time. AF-area mode determines which part of the frame is considered. These are separate decisions.

Picture this

Choose a single focus area over a stationary object. Then compare a broader automatic area.

Keep in mind.

Low contrast, poor light, repeating patterns and obstructions can make autofocus unreliable.
