EF-530 DG SUPER features a powerful Guide Number of 53 and is designed to work with the latest TTL auto exposure systems of all popular manufacturers’ digital and film SLR cameras. It features TTL automatic flash exposure control for easy operation.
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 24 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-530 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-530 DG SUPER units while preserving the automatic TTL control function. The model for Sigma, Sony and Pentax uses the camera's built-in flash for signaling, and makes the EF-530 DG SUPER located away from the camera to fire. The model for Canon utilises an EF-530 DG SUPER mounted on the camera for signaling, and triggers and controls single or multiple EF-530 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- 530 DG SUPER mounted on the camera. The Designated Slave-flash function triggers multiple, units of the EF-530 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-530 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-530 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, Sony, 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.
A full range of advanced functions
The EF-530 DG SUPER is packed with convenient functions, including the "Multi-Pulse Flash Function," which exposes a series of images onto a single frame, and the "Auto Power-Off Function," which automatically shuts off the power. It also features a red-eye reduction function, an exposure compensation function, an exposure-control checking function, and many others.
