The Canon 580 flash is a great addition to our lighting inventory. The 360 degree swivel head allows us to get any lighting angle we need on a subject. With a metal hot shoe you can adapt the flash right on top of your camera. The more consistent color and enhanced controls help our cameras achieve the best quality photos. By making sure our camera has the best lighting, the flash exposure lock that targets our subject helps us do just that.
