The Bower SFD829TW Digital Slave Twin Flash is a slave flash that is compatible with almost all digital cameras, with or without built-in flash capability. It works as a slave flash, and can be set for a single flash camera or a pre-flash camera.
It also has a hot shoe so that it can be fired from the camera directly, and the flash is fully synchronized with fill-in flash and red-eye reduction flash and can be used with virtually all of the digital cameras on the market.
The main flash can be bounced or swiveled, and when combined with the smaller secondary flash, can result in perfectly exposed portraits or close-ups. The secondary flash bulb can be turned off, if not required.
