Advanced features and high performance allows photographers to express their intentions accurately. The EF-500 DG SUPER is designed to work with both AF 35mm SLR and DIGITAL cameras of all-popular manufacturers. The EF-500 DG SUPER is a multifunctional shoe mount type flash that provides a large amount of light, featuring a guide number of 50/m (165/ft) w/ISO 100.
Among the diverse features of this flash, are the Autozoom function, which automatically sets the illumination angle in accordance with the focal length of the lens; TTL exposure control, which automatically regulates the amount of flash light; bounce and swivel head functions, which come in very handy for bounce photography; FP flash, which is capable of synchronizing the flash illumination with high shutter speeds; and the rear curtain synchro flash mechanism, which makes delayed synchro photography possible. A wireless slave function is also available for use with compatible cameras.
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 channel (with manual exposure control). The Normal Slave-flash function can be used to synchronize one or more EF-500 DG SUPER flashes with the camera's internal flash or other flash equipment (with manual exposure control).
Modeling flash function to check for shadows Like a studio flash unit equipped with a modeling lamp, the EF-500 DG SUPER also offers a modeling flash function, enabling the user to check for intense reflections and shadows, before actually taking the flash picture. (for Sigma, Minolta, Canon, and Pentax cameras).
FP flash function for high shutter speeds For focal-plane shutters, the flash synchronization speed is limited to coincide with full shutter opening, thus limiting the use of high shutter speeds with flash. The FP Flash function makes flash photography possible at shutter speeds greater than the normal synchronization speed. When the lens diaphragm is set to larger apertures to limit depth of field in synchronized daytime shooting, high shutter speeds can be used to balance the daylight and the flash light, at any shutter speed.
Rear-curtain synchro flash mechanism for natural representation of motion When shooting a moving subject in slow synchro photography, selection of the rear-curtain synchro mode allows the flash to be triggered immediately before the rear-curtain of the shutter closes. Unlike front-curtain synchro, this mode records blurred trails behind the subject rather than in front, for a more natural expression of motion.
