With the Pixel e-TTL Radio Trigger Set King Pro you can control multiple camera flashes from your Canon camera up to 300 meters. The set supports automatic TTL communication, but you can also set it manually. This makes it possible to divide the camera flash units into groups with multiple King Pro receivers. You can then set the exposure for each group. It is also possible to adjust the EV corrections, light ratio, synchronization mode and zoom settings.
The King Pro is suitable for the following models: 1D series, 5D series, 7D series, 6D, 70D, 60D, 50D, 40D, 30D, 20D, 10D, 760D, 750D, 700D, 650D, 600D, 550D, 500D, 450D, 400D, 350D, 300D, 100D, 1300D, 1200D, 1100D and 1000D.
