Autozoom function for changing the illumination angle This function automatically sets the optimum illumination angle in accordance with the lens' focal length, in a range from 28 mm to 105 mm. When the built-in Wide Panel is used, the flash can cover the angle of up to that of a 17mm lens. Automatic TTL exposure control supporting a diverse array of illumination methods Various forms of illumination, such as the diffusion effect achieved by attaching a diffuser to the flash head. Bounce flash, using a reflector, without directly illuminating the subject with flash light, can be accomplished, while maintaining automatic exposure control. Bounce-flash function with movable flash head The flash head can be tilted up by up to 90 degrees , to the left by 180 degrees , or to the right by 90 degrees . Bounce photography, in which light is reflected off a white wall or the ceiling or a reflector, increases your range of photographic expression. As the flash head can also be tilted down by 7 degrees , light can be effectively used even for close-up shots. Wireless-slave-flash functions The EF-500 DG SUPER provides the TTL wireless-slave-flash functions, which allows the flash to be moved to a location away from the camera for operation. The TTL wireless-flash function enables the control of multiple EF-500 DG SUPER units while preserving the automatic TTL control function. The model for Sigma, Minolta and Pentax uses the camera's built-in flash for signaling, and makes the EF-500DG SUPER located away from the camera to fire. The model for Canon utilizes an EF-500 DG SUPER mounted on the camera for signaling, and triggers and controls single or multiple EF-500 DG SUPER units, located away from the camera. In this procedure, the signaling and flash triggering are performed by changing the settings of the EF- 500 DG SUPER mounted on the camera. The Designated Slave-flash function triggers multiple, units of the EF-500 DG SUPER, each corresponding to a preset c
