A flash that coordinates with the camera s exposure, and sometimes focusing systems. Dedicated flashes may, among other things, automatically pick up the loaded film s ISO, set the camera shutter speed to X-sync, and tell the camera when its ready to fire. Flashes dedicated to autofocusing cameras may also vary their angle of flash throw according to the lens in use (even with zoom lenses), and contain autofocus beams that aid focusing in very dim light or even total darkness. For outdoor work, dedicated flashes may provide totally automatic fill-flash exposure. In short, a dedicated flash can be make flash photography as simple as automated natural light photography.ritzcamera
An electronic flash unit that integrates automatically with a specific camera’s exposure meter and exposure controls, permitting simplified, fully-automatic use of the flash. A dedicated flash is designed to work with a particular model, brand or type of camera.
An Electronic Flash Unit that is made to be used directly with a specific make or model of a camera. Canon, Nikon Minolta and Olympus for example, ll have electrical contacts in the hotshoe which passes TTL (through the lens) metering and AF range information to and from the flash unit or speedlight. You cannot interchange flash units and cameras. I.e. a Nikon speedlight on a Canon camera.
A fully automatic flashthat works only with specific cameras. Dedicated flash units automatically set theproper flash sync speed and lens aperture, and electronic sensors within the cameraautomatically control exposure by regulating the amount of light from the flash.A simple glance can differentiate by identifying the multiple contacts on the hotshoe (the place where the flash is mounted).

A portable flash gun which can be coupled with an automatic camera and can then be controlled by the camera s programmed functions.
