This flash unit provides automatic Through-The-Lens (TTL) control of the flash exposure 

when used with dedicated digital cameras. When using this mode, the flash unit will 

automatically emit the flash output for a balanced illumination of the subject and 

background. The inbuilt AF infra-red assistance beam will turn on automatically to assist 

the camera to focus in low lighting conditions.
