The RPS Studio Digital Flash Bracket combines many features desired for flash photography while incorporating features that have not been available to the photographer doing flash photography with a digital SLR.
The first feature is an included electronic shutter release. This two position release allows the camera to set the exposure and auto focus and fire the shutter. Prior to this feature being included, the photographer would have to adjust the zoom of the lens and then reach back to the shutter button on the camera to take the shoot. This took a lot of time and could result in the loss of a good shot. The inclusion of the shutter release means that the lens can be zoomed or if not in auto focus mode, focused, and the shutter fired at any time without having to move the had back to the shutter release button on the camera.
