Its support for the FP mode (high-speed flash sync) means the flash can be fired at any shutter speed. This means you can concentrate on shooting when a faster shutter speed is required, for example, in order to use a near-maximum aperture to produce beautiful bokeh. EF-X500 also supports multi-flash lighting. Set up multiple flashes to freely control light on a subject and background for a creative result.
TTL lighting control is available with single flash and also in the multi-flash setup, so that you can start shooting without having to make cumbersome adjustments to light output.
