AF Modes: Differences between One-Shot AF and Servo AF (EOS M)

In the ⋖M⋗, ⋖Av⋗, ⋖Tv⋗, and ⋖P⋗ shooting modes, you can select the AF (Autofocus) operation to suit the shooting condition or subject. In Basic Zone modes, the optimum AF operation is set for the respective shooting mode.

One-Shot AF for Still Subjects

Suited for still subjects. When you press the shutter button halfway, the camera will focus only once.

Caution

If focus cannot be achieved, the AF frame will turn orange. If this occurs, the picture cannot be taken even if the shutter button is pressed completely. Recompose the picture and try to focus again. Or see "Shooting conditions that make focusing difficult".

If [ : Beep] is set to [Disable], the beeper will not sound when focus is achieved.

Servo AF for Subjects Moving Back and Forth

This AF operation is suited for focusing subjects that are moving back and forth. During continuous shooting, the focusing mode for all the shots after the first one will depend on the lens used.

When an EF-M lens is attached, the AF frame selected will be fixed and the camera will keep focusing the subject within the selected AF frame. When an EF or EF-S lens is attached, AF lock will be used.

Caution
