Slave Flash Units for Digital Cameras

What are Slave Flash Products for Digital Cameras and Why are They Needed?

Digital cameras such as the popular Olympus D600L usually have an inadequate built in flash and lack any facility to use an external flash. Standard slave flash units will not work with most digital cameras because these cameras use a very rapid pre-flash (we're not talking about red-eye reduction). The first flash is used to set the white balance of the camera's CCD chip - not the exposure. A typical slave unit will fire on the first flash it senses while the digital camera captures the image on the second flash. Thus the extra light from the slave does not show up in the digital camera photo.

Our slave flash units are specially designed to fire on the second flash sensed by their built in optical sensors thus solving the digital camera flash problem. On the dual mode DSF-1s, a switch on the back allows the user to select whether the unit fires on the first or second flash. This allows the DSF-1s to be used with any camera - digital or conventional. It also accomodates digital cameras that do not use a pre-flash. The new RF-50 Ring Flash has built in digital slave circuitry and needs only to be screwed on to the lens threads of your camera (step-up ring for Oly D600L included) for great shadow free macro work such as dental and catalog photography. And since our slave flash products have built in digital slave circuitry, no electrical connection to the camera is required.

The first shot was taken with Olympus D600L built in flash. The second was taken with the DSF-1 Added.
