Canon Speedlite 244T Set (Consists of Speedlite 244T and case, exclusive use with the ' T" Serief camera, but usable with other FD-mount Canon system camera models).
Designed exclusively for the Canon T-series cameras, the Speedlite 244T makes fully-automatic, programmed flash photography a reality. It has just two controls: an on/off switch and film speed selector (ISO 100, ISO 400). When the flash is charged (indicated by a "s" in the finder), slightly depress the camera's shutter button and the programmed infrared flash element fires a low-intensity beam. The light received from the infrared pre-flash is detected by a sensor and the unit is programmed to automatically set the lens aperture to f/2.8, f/4, or f/5.6, depending on flash-to-subject distance and reflectivity.
