Menu Function Settings
Movie Servo AF speed
N
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 only enabled
when using a lens compatible with 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 set the AF adjustment speed (focus
transition speed) to one of five levels, from standard
speed to slow, to obtain the desired effect.
* Lenses supporting slow focus transition during movie shooting
USM lenses marketed in 2009 or later and STM lenses (for example,
the EF-S18-135mm f/3.5-5.6 IS STM) support slow focus transition
during movie shooting. For details, refer to the Canon website.
If
L8
(59.94 fps) or
7
(50.00 fps) is set, Movie Servo AF will not
function and therefore the settings above will not be available.
If [ AF method ] is set to [
u
+Tracking ] or [ FlexiZone - Multi ], the AF
adjustment speed will be equivalent to the [ Standard ] setting.
