How to improve the ability of the camera to focus on a subject in a dark environment.

Applicable Products and Categories of This Article

In order to achieve better focus in dark shooting environments, the AF Illuminator feature that is available on select Sony® cameras should be set to Auto.

IMPORTANT: For model-specific information and to check if your camera has an AF Illuminator feature, refer to the operating instructions supplied with the product. Manuals are posted on your model support page.


  • If the AF Illuminator light does not reach the subject sufficiently or the subject has no contrast, focus will not be achieved.
  • Focus can be achieved as long as the AF Illuminator light reaches the subject, even if the light is slightly off-center of the subject.
  • The AF Illuminator does not function on cameras with a Face Detection feature when Face Detection is set to On.
  • Although there are no safety issues, directly looking into the AF Illuminator light at close range is not recommended.
