About the AF Sensor
The camera’s AF sensor has 61 AF points. The illustration below shows the AF sensor pattern corresponding to each AF point. With f/2.8 or larger maximum aperture lenses,
Depending on the lens attached to the camera, the number of usable AF points and AF pattern will differ. For details, see pages 76 to 81.

These focusing sensors are geared to achieve higher precision focusing with f/2.8 or larger maximum aperture lenses. A diagonal cross pattern makes it easier to focus subjects that may be difficult to focus. They cover the five vertical AF points at the center.
These focusing sensors are geared to achieve high- precision focusing with f/4 or larger maximum aperture lenses. Since they have a horizontal pattern, they can detect vertical lines.
These focusing sensors are geared for f/5.6 or larger maximum aperture lenses. Since they have a horizontal pattern, they can detect vertical lines. They cover the three columns of AF points at the viewfinder’s center.
These focusing sensors are geared for f/5.6 or larger maximum aperture lenses. They can detect horizontal lines and cover all 61 AF points in a vertical pattern.
