Pentax SF1 - Page 35

AF SINGLE Mode
• The shutter cannot be released until the subject is in
focus.
• Focusing is fixed as long as you press the shutter release
button halfway down with the green in-focus signal [O]
on. (See page 32 about the focus-lock function.) To
change the direction of shooting after focusing is fixed,
it is necessary to let the shutter release button go and
press it again.
• If you press the shutter release button ail the way
down in one movement, the shutter is released after
the subject is in focus.
• The "Snap-in-Focus" can be used in combination with
a Pentax K/\- or K-mount lens. Adjust the focus manually
at the point you expect to capture the subject and hold
the shutter release button all the way down. The shutter
will release automatically as soon as the subject moves
into the prefocused area.
AF SERVO Mode
• In the AF SERVO mode, you can release the shutter
anytime, regardless of the focusing situation. As long as
you press the shutter release button halfway down, the
camera continues focusing on the subject even when it
is moving.
• If you release the shutter when the green in-focus
signal [o] lights up, the subject is captured In focus.
How to Hold the Camera
To take sharply focused pictures, it is essential to hold
the camera properly. The shutter release button should
be pressed softly while you hold your breath, since
a sudden, rough release can cause camera shake and
produce blurred images. Brace the camera and your
body on a tree, building or table. When using a slow
shutter speed or a telephone lens, the use of a tripod
and the Cable Switch F is recommended.
