Using Af To Focus (Af Method) - Canon EOS 70D Instruction Manual

Using AF to Focus (AF Method)

Changes in AF Speed Depending On the AF Control Method
If the AF method is set to [u+Tracking], [FlexiZone - Multi], or [FlexiZone
- Single] for Live View shooting or movie shooting, the AF control method
(phase-difference detection with the image sensor or contrast detection) will
switch automatically depending on the lens used and functions selected, such
as movie digital zoom or magnified view. This can greatly affect the AF speed
and the camera may take a longer time to focus (phase-difference detection
generally allows faster AF focusing). For details, refer to Canon Web site.
Selecting the AF Method
You can select an AF method to suit the shooting conditions and your
subject. The following AF methods are provided: [u(face)+Tracking],
[FlexiZone - Multi] (p.125), [FlexiZone - Single] (p.126), and [Quick
mode] (p.127).
If you want to achieve precise focus, set the lens focus mode switch to
<MF>, magnify the image, and focus manually (p.130).
u(face)+Tracking:c
The camera detects and focuses human faces. If a face moves, the AF
point <p> also moves to track the face.
