This handy flash adds extra illumination power for flash photography. There is no need for any awkward cables, as the HVL-FSL1 automatically syncs with the camera's onboard flash - it even works with pre-flash. It extends the effective flash range up to 16 feet and offers manual control of power output (low/medium/high). This compact but powerful accessory is a hot addition for any digital photographer.
