Hot shoes
Many cameras have a hot shoe into which you can slide and lock an external flash that’s designed to work with the camera. The electrical connections to the camera’s shutter release and autoexposure system are made automatically when the flash is locked in place. There are also adapters for the hot shoe that let you connect strobes or off-camera flash units.
