AF Sensor

45 AF points are available in viewfi nder shooting.

Cross-type focusing: f/5.6 vertical + f/5.6 horizontal

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 diffi cult 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.

Lenses and Usable AF Points

The number of available AF points and the focusing patterns used vary by
lens group (A–H). Fewer AF points are available for lenses in groups E–H.

AF points in [

[ / ] points remain lit.)

The number of AF points varies depending on your specifi ed still image

aspect ratio.

Group A

Autofocusing with 45 points is possible. All the AF area selection modes are
selectable.

exceeding f/8), focus may not be achieved with AF when shooting low-contrast
or low-light subjects.
