the left AF Area Selection Mode icon selected and a single large AF Point among the
smaller AF Points in the Viewfinder, as shown in Figure 165 - left. You can also use the
Quick Control screen to change this setting by selecting the AF Area Selection Mode
icon.
 Tap the Shutter Button with a half-press to wake up the camera.
 To select your own desired AF Point, while looking through the Viewfinder use
your thumb on the Multi-Controller to select the focus point that is nearest to
where you want to focus. Press the Multi-Controller up, down, side-to-side, or
diagonal. If you did not set the Custom Control for AF Point Direct Selection, you
will need to press the AF Point Selection Button first before using the Multi-
Controller to move the AF Point.
 Place that AF Point over your intended subject or detail (see Figure 166).
 Press and hold the Shutter Button halfway down and see that point blink (if
Custom Function C.Fn II-15: VF Display Illumination is set for Enable). The
Focus Confirmation Light should light up in your Viewfinder, and the camera will
beep if you have that enabled. You have locked the focus.
 Keeping the Shutter Button pressed halfway to keep the focus distance locked,
recompose if necessary, and take the shot by fully pressing the Shutter Button.
If the Focus Confirmation Light does not light up and the camera does not take the
photo, the camera may not be finding enough contrast to focus on, you may be too
close to your subject for the lens to focus, or the lighting may be too dim for the AF
system to work properly. Try using the center AF Point, which performs better in low
light, and is a more sensitive cross-type point with certain lenses (having an f/2.8 or
wider maximum aperture). Or you may be in AI Servo AF mode, which does not lock
focus in this manner because it is tracking a moving subject. Note that the area that the
camera evaluates for focus is slightly larger than the actual active AF Point squares you
see in the Viewfinder. In rare situations when autofocusing fails, you can also resort to
manual focusing by switching your lens to MF and using the lens focusing ring. Or you
can autofocus on an object at the same distance from the camera as the subject, and
then recompose the image back to the subject. This technique can also be used in other
situations such as a sporting event, where you pre-focus at a specific spot or distance
and wait for the subject to get to that point - so that the camera is already in proper
focus and the moment or subject can be captured.
With the use of certain lenses or lenses plus an extender, some AF Points will be seen
to blink in the Viewfinder. This indicates that those AF Points are not acting as cross-
type points. This will occur with Canon lenses designated as Group C through G in the
Canon EOS 80D Instruction Manual on pages 128-135. And with lenses in Group E
through H, not all 45 AF Points will be available for selection. Lenses in these groups
are typically older lenses, telephoto lenses, or lenses being used with an extender.
