Equal priority
This setting gives an equal priority to both focus and shutter-
release
Release priority
This setting gives priority to shutter-release and will capture
an image even if it is out of focus. It is effective when you
want to minimize any delay when shooting, sacrificing AF
performance
Focus priority
This setting gives priority to focusing on a subject and it

recommended when you want to ensure your images are in
focus sacrificing response speed.
Equal priority
This setting gives an equal priority to both focus and shooting
speed during continuous shooting. The speed of continuous
shooting may also slow down when it is dark, or in low-
contrast.
Shooting speed priority
This setting gives priority to a continuous shooting speed
rather than priority on focus. Continuous shooting speed will
not drop. Effective when you want to shoot with a fixed
inter val bet ween photos. A set ting of [-2] will maintain
continuous shooting speed.
Focus priority
This setting gives priority to focusing rather than continuous
shooting speed. It cannot shoot a picture unless it is in focus,
greatly reducing continuous shooting speed. It is recommended
when you want to shoot only after focusing on the subject.
This parameter makes the most of AF low-light performance
improved by the firmware upgrade.

[One-Shot AF release priority]
The [AF2] and [AF3] tabs include settings related
to AF operation parameters and shutter-release
timing. With these items it is possible to set
which has priority (or a balance) between
focusing with AF, and the shutter-release.
The [AF2] tab contains the [AI Servo 1st image
priority] and [AI Servo 2nd image priority]
parameters for AI Servo AF. The priority on
focus and shutter-release can be set for both
the 1st image and subsequent images during
continuous shooting. With [Focus priority],
shooting is delayed until after the camera has
focus on a subject (this could be just a few
milliseconds). With [Release priority/Shooting
speed priority] shooting takes place instantly
without waiting to focus, resulting in possible
Focus priority

out of focus images. The default [Balance
priority] sets equal priority on both (attempting
to focus without major delays to shutter release
timings), ideal for most shooting situations. To
make use of low-light performance improved
by the firmware upgrade during continuous
shooting, set the [During continuous shooting]
parameter to [Focus priority: +2].
When using One Shot AF the shooting priority
can also be altered via the [One-Shot AF release
priority] option in the [AF3] tab. The priority of
focusing and shutter-release can be altered in
the same way as about during AI servo AF.
However there is no [Balance priority], and
instead [Focus priority] is the default setting.
