Rent this controller to work with your Canon camera and Profoto lights setup. Set your exposure to the perfect settings and communicate with all your off-camera lights within a 1000 ft range. With certain Profoto systems you also have the ability to shoot at high speed and capture images with shutter speeds up to 1/8000 second. Interference with other systems is minimized by using 8 channels and 3 groups (those groups can be controlled separately). An impressive amount of customization, ease, and control is packed into this one little controller!
