AF Sensor
The camera's AF sensor has 45 AF points. AF sensor patterns formed by the AF points are
as follows. High-precision AF centered in the viewfinder is possible using lenses with a
maximum aperture up to f/2.8.
Warning
The number of available AF points, the focusing patterns, and the Area AF frame
shape vary by lens. For details, refer to Compatible Lenses and Autofocusing
(Viewfinder Shooting).

(1) Cross-type focusing: f/5.6 vertical + f/5.6 horizontal
(some also supporting f/8)
(2) Dual cross-type focusing: f/2.8 right diagonal + f/2.8 left diagona
f/5.6 vertical + f/5.6 horizontal (also supporting f/8)
This focusing sensor is geared to obtain higher-precision
focusing for lenses with a maximum aperture value as low as
f/2.8. A diagonal cross pattern makes it easier to focus on the
subjects that may be difficult to focus. It is provided at the
center AF point.
These focusing sensors are geared for lenses with a maximum
aperture value as low as f/5.6 (and some supporting f/8). Since
they have a horizontal pattern, they can detect vertical lines.
They cover all 45 AF points.
