- The camera focuses on the subject continuously even when you are not pressing the shutter button halfway.
- Since this drives the lens continuously, it will consume battery power and shorten the total possible movie shooting time.
- With certain lenses, the lens operation noise during focusing may be recorded. If this happens, use an external microphone (commercially available) to reduce lens operation noise in the movie. Also, using the EF-S18-135mm f/3.5-5.6 IS STM lens will reduce lens operation noise.
- If you want to set the lens’s focus mode switch to <MF> during Movie Servo AF, first set the Live View shooting/Movie shooting switch to <

IMPORTANT
Cautions When [Movie Servo AF] is Set to [Enable]
- Movie Servo AF will pause during zooming or magnified view.
- During movie shooting, if a subject approaches or moves away or if the camera is moved vertically or horizontally (panning), the recorded movie image may momentarily expand or contract (change in image magnification).
- If
(59.94 fps) or 
(50.00 fps) is set, Movie Servo AF will not work. Also, since contrast detection is used for AF control, it may take longer to focus.
REFERENCE
<Shooting Conditions that Make Focusing Difficult>
- Subject with low-contrast such as the blue sky, solid-color flat surfaces or when highlight or shadow details are lost.
- Subjects in low light.
- Stripes and other patterns where there is contrast only in the horizontal direction.
- Subjects with repetitive patterns (skyscraper windows, computer keyboards, etc.).
- Fine lines and subject outlines.
- Under a light source whose brightness, color, or pattern keeps changing.
- Night scenes or dots of light.
- Under fluorescent or LED lighting when the image flickers.
- Extremely small subjects.
- Subjects at the edge of the picture.
- Subjects strongly reflecting light.
- Near and distant subjects covered by an AF point (such as an animal in a cage).
- Subjects that keep moving within the AF point and cannot keep still due to camera shake or subject blur.
- A subject approaching or moving away from the camera.
- Performing AF while the subject is very far out of focus.
- Soft focus effect is applied with a soft focus lens.
- A special effect filter is used.
- Noise (spots, banding, etc.) appears on the screen during AF.
Press the shutter button halfway or press the <AF-ON> button to focus.
