3 Menu Function Settings Movie Servo AF speedN 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-S 18-135mm f/3.5-5.6 IS STM) support slow focus transition during movie shooting. For details, refer to the Canon Web site. 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. 345
