Digital Tele-Converter
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 <
n> button, choose
[Digital Zoom] on the [
4] tab, and then

The view is enlarged and the zoom factor
is displayed on the screen.
•
The digital tele-converter cannot be used with digital zoom
(
=
32 ) or AF-point zoom (
=
39 ).
•
The respective focal lengths when using [1.6x] and [2.0x] are 44.8 – 716.8 mm
and 56.0 – 896.0 mm (35mm film equivalent).
•
The shutter speed may be equivalent when you move the zoom lever all the
way toward <
i> 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)” (
= 32 ).

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 < n> button and set [AF Frame
Size] on the [
4] tab to [Small] ( =
24 ).
• The AF frame size is set to [Normal] when you use the digital zoom ( = 32 )
or digital tele-converter (
=
59 ), and in manual focus mode (
=
58 ).
• 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).
