One AF frame is displayed in the center. Effective for reliable focusing.
● A yellow AF frame is displayed with [ ] if the camera cannot
focus when you press the shutter button halfway.
● To reduce the AF frame size, press the [ ] button and set
[AF Frame Size] on the [ ] tab to [Small] (= 29).
● The AF frame size is set to [Normal] when you use the digital
zoom (= 38) or digital tele-converter (= 77), and in manual
focus mode (= 75).
● To compose shots so that subjects are positioned at the edge or
in a corner, first aim the camera to capture the subject in an AF
frame, and then hold the shutter button halfway down. As you
continue to hold the shutter button halfway, recompose the shot
as desired, and then press the shutter button all the way down
(Focus Lock).
● The AF frame position is enlarged when you press the shutter
button halfway with [AF-Point Zoom] (= 51) set to [On].

● Detects people’s faces, and then sets the focus, exposure (evaluative
metering only), and white balance ([ ] only).
● After you aim the camera at the subject, a white frame is displayed
around the person’s face determined by the camera to be the main
subject, and up to two gray frames are displayed around other
detected faces.
● When the camera detects movement, frames will follow moving
subjects, within a certain range.
● After you press the shutter button halfway, up to nine green frames are
displayed around faces in focus.
Digital Tele-Converter
Still Images Movies
The focal length of the lens can be increased by approximately 1.6x or
2.0x. This can reduce camera shake because the shutter speed is faster
than it would be if you zoomed (including using digital zoom) in to the
same zoom factor.
● Press the [ ] button, choose
[Digital Zoom] on the [ ] tab, and then
choose the desired option (= 29).
● The view is enlarged and the zoom factor
is displayed on the screen.
● The shutter speed may be equivalent when you move the zoom
lever all the way toward [
] for maximum telephoto, and when
you zoom in to enlarge the subject to the same size following step
2 in “Zooming In Closer on Subjects (Digital Zoom)” (= 38).
