DESC: The flash is a supplementary unit that operates wirelessly and increases the effective flash range up to approximately 30 feet. The HF-DC1 flash is supplied with a mounting bracket so it can be attached to the camera, but it can also be hand-held or mounted on a tripod or accessory light stand to adjust the lighting angle for pro-like quality results. Multiple HF-DC1 units can be synchronized with a single camera for even greater lighting flexibility. This smart high powered slave flash unit is compact and compatible with almost every PowerShot digital camera.
