45-point Area AF, 8 mm (vertical) × 15 mm (horizontal)
* The 7 focusing points at the center are cross-type
sensors which are also vertical-line sensitive.
The mode can be switched between the following three:
(1) One-Shot AF
Autofocus locks when focus is achieved.
* AF-priority: The shutter can be released only when
focus is achieved.
* During evaluative metering, AE lock is set at the
same time as AF lock. (In the other metering modes,
exposure metering continues in real-time until the
shutter is released.)
(2) AI Servo AF
Constantly tracks subject movement up to the start
of exposure.
* While the shutter button is pressed halfway, the
shutter button can be depressed fully at anytime to
release the shutter regardless of focus. (Shutter
release-priority)
* When the shutter button is pressed completely with-
out pressing it halfway first, the shutter is released
after AF operation is executed once.
* During continuous shooting of a moving subject, the
lens is driven (taking 0 to 250 ms) from the second
successive frame to track the subject, then the shut-
ter is released.
* No in-focus indicator. The indicator only blinks (8 Hz)
if AF fails.
(3) Manual focusing
Switching from AF to manual focusing
* With mechanical manual-focus lenses, the focus
mode is switched to manual with the lens.
* With electronic manual-focus lenses, the focus mode
can be switched to manual as above or automatically
with CF-7-0).
When focus is achieved, the in-focus indicator and
superimposed focusing point light up. If focus fails,
neither is displayed.
