It is sometimes difficult to achieve a fine focus with the auto focus when shooting movies.

Applicable Products and Categories of This Article

When shooting a subject that moves forward or backward with a shallow depth of field, it may be difficult for the camera to focus and track the subject automatically.
In addition, the auto focus has difficulty with certain subjects.

If it is difficult to auto focus, adjust the focus manually or press the PHOTO button halfway down during movie shooting. When the button is pressed, the camera performs as if it is set to AF-S (Single-shot AF) in Autofocus Mode, which makes focusing easier.

NOTE: When an A-mount lens is attached with an LA-EA1 or LA-EA3 Mount Adaptor, the auto focusing speed is slower than when an E-mount lens is attached. It takes approximately 2 to 7 seconds (*1).

(*1): These values were measured under conditions designated by Sony. The length of time may vary depending on factors such as the lens used and the brightness of the subject during shooting.
