Dramatically improve your image and video quality. With todays high definition DSLR cameras every photographer and videographer knows that a quality flash unit and video light are essential components to taking great pictures and quality video. Built-in flashes simply dont have enough power to properly illuminate most subjects, and typically produce harsh shadows, red-eye and other undesirable effects due to their lack of a bounce feature. Built-in video lights are not even an option on most cameras. This external flash with LED video light offers power and versatility you need, resulting in consistently better pictures and higher quality video.Specifications Flash Type: Automatic Compatibility: Universal (Hot Shoe) Guide Number: 40(105m) / 131ft.
