The SF4000 Bounce Zoom Slave Flash from Vivitar can be used as both a normal bounce zoom flash or as a slave. This flash features 4 slave modes that allow it to work with cameras that fire their built-in flash immediately or cameras that have a single or multiple flash red eye reduction system. Please check your cameras instruction manual to determine which flash system your camera has.

The SF400 has a multi-angle 3-position zoom head that covers wide angle, normal, and telephoto distances. It is compatible with Canon, Nikon, Panasonic, Sony, Olympus, and Minolta digital SLR Cameras.
