Flash lighting is the main tool in the photographer's arsenal. Broadly speaking, speedlights can be divided into two categories: manually adjustable (frequently called OCF lights, where OCF stands for Off-Camera Flash) units and automated TTL lights that use the camera's through-the-lens metering capabilities to control their power output.
By their very definition, OCF speedlights are compatible with practically every make and model of photographic camera, as they do not require a specialized data connection to communicate with the camera. TTL flashes are the complete opposite — their automated features will work only when used with a compatible camera brand (but a TTL flash can be used in manual mode just as well as an OCF flash...).
