Focus is a combination of lens aperture and light. Photo by: ‘Unsplash’. Smaller apertures, such as f/8 to f/16, will “force” all the light coming from outside to pass through a tiny hole and concentrate on the image sensor. As a result, a bigger part of the image will be in focus.

Linear focus points can detect changes in image contrast only along either the horizontal or vertical dimension. These autofocus points are less reliable, since autofocus efficiency depends on the type of lines in your frame and how the sensor is placed.
How many focus points are there in a photo?
