3 Menu Function Settings
 Movie Servo AF speedO
You can set the Movie Servo AF’s AF
speed and its operation conditions.
This function is settable when [Movie
Servo AF] is set to [Enable] and [AF
method] is set to [FlexiZone - Single].
Additionally, the function is enabled
when using a lens supporting slow focus
transition during movie shooting*.
When active : [Always on] sets the AF adjustment speed to take effect
at all times for movie shooting (before and during movie
shooting). [During shooting] sets the AF adjustment
speed to take effect only during movie shooting.
AF speed : You can adjust the AF speed (focus transition speed)
from standard speed to slow (one of seven levels) or
fast (one of two levels), to obtain the desired effect for
movie creation.
* Lenses supporting slow focus transition during movie shooting
USM lenses released in and after 2009 (for example, the EF-S 18-
135mm f/3.5-5.6 IS USM) and STM lenses (for example, the EF-S 18-
55mm f/3.5-5.6 IS STM) support slow focus transition during movie
shooting. For details, refer to the Canon website.
If [AF method] is set to [u+Tracking] or [FlexiZone - Multi], the operation
will be the same as when [AF speed] is set to [Standard (0)].
