3.5 Focus Modes
To use the Auto Focus function, both the camera body and the lens have
to be set to their respective Auto Focus modes. Auto Focus does not
function when either the camera body or the lens are set to manual focus.
To activate Auto Focus (AF), first select AF on the focusing selector
ring on the lens. Next, adjust the Focus Mode Selector Lever to either
S (single) or C (continuously) Auto focusing on the camera. The Focus
selection ring on the lens can help you to rapidly switch between AF and
M, without having to change your grip of the camera.
The shutter release button has a two-step action. When pressed lightly
it stops at a certain point. In this manual, this position is called the
half-
press
position. When you
half-press
this button, the camera functions are
activated. When the shutter button is pressed further down, the shutter is
released. This position is called the
full-press position.
1. Aim the camera so that the subject is within the focus frame.
2. Half-press the shutter release button, and focus is adjusted
automatically in AF mode. As default, you can now re-compose your
image without losing the original focus setting, by moving the camera
and keeping the shutter release button half-pressed. When the focus
mark lights up, the subject is in focus.
3. When the focus mark lights up, press the shutter release button
further down to release the shutter. (The focus mark is an illuminated
dot (indicated as this • symbol) at the bottom of the viewfinder display.
See the focus mark in the illustration circled in red).

When the picture is not focused the shutter cannot be released when in
single focus mode. Either press the shutter release button again to adjust
the focus or move the camera to change the position of the focus frame.
Lenses without the focus mode selector ring are automatically set to AF
if the camera is set to Auto Focus. Do not touch the focus ring as you
may cause internal damage to the camera Auto Focus motor.
Lenses with the Focus Mode Selector
The focus modes can be switched between automatic and manual
with the selector on the lens when the focus mode selector lever on the
camera body is set to S or C.
