Canon EOS 5DS (no lens included) Manual De Propietario

99

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, high-precision AF is possible at the viewfinder center.
Depending on the lens attached to the camera, the number of usable 
AF points and AF pattern will differ. For details, see pages 100-108.

These focusing sensors are geared to obtain 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 
AF points vertically aligned at the center.

These focusing sensors are geared to obtain 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. The center AF 
point and the adjacent AF points at the top and bottom are 
compatible with f/8 or larger maximum-aperture lenses.

These focusing sensors are geared for f/5.6 or larger maximum 
aperture lenses. Since they have a vertical pattern, they can 
detect horizontal lines. They cover all 61 AF points. The center 
AF point and the adjacent AF points on the left and on the right 
are compatible with f/8 or larger maximum-aperture lenses.
