SIGMA EF-630 Electronic Flash for Cameras - Manual (Page 2)

Intuitive user interface for ease of use
The new dot matrix liquid crystal display ensures improved visibility of menu functions. Moreover, the
D-Pad and dial on the side of the flashgun make changing settings easier than ever. An intuitive user
interface enhances the compatibility between the EF-630 flash and the SIGMA sd Quattro series. The
flash is designed to disengage easily by one-click on the shoe lock lever. In addition, a flash sync
terminal and a notification sound when the flashgun is fully charged improve the ease of use.
Bounce-flash function with movable flash head.
The flash head of the EF-630 can be tilted up by as much as 90° and swivel both left and right by 180°.
Bounce photography, where light is reflected off a white wall, ceiling or a reflector increases the range
of photographic expression. The flash head can also be tilted down by 7° for close-up shots.
TTL Wireless Flash Function
The TTL wireless flash function will adjust the desired flash exposure automatically even if the EF-630
is disengaged from the camera. Remote control operation is possible between the camera and flash.
When multiple flash units are used, the camera calculates the correct exposure automatically.
Modeling Flash function to check for shadows.
The EF-630 also offers a modeling flash function, enabling the user to check for intense reflections
and shadows before taking a photograph.
Rear-curtain Sync flash function for natural representation of motion.
When photographing a moving subject, the Rear-curtain Sync mode allows the flash to be triggered
immediately before the rear-curtain of the shutter closes. Unlike Front-curtain Sync, this mode
records blurred trails behind a moving subject rather than in front for a more natural expression of
motion.
