The Pixel e-TTL King Pro Radio Trigger Set is an advanced trigger set for speedlites compatible with Canon. The e-TTL King Pro Trigger Set supports both, manual and automatic TTL communication with the camera and has a range of 300 meters. With the use of additional receivers, multiple speedlites can be used and divided into groups. The lighting values for each of these groups can also be set individually. Further, with the e-TTL radio trigger set, EV corrections, sync-mode (1st/2nd curtain, highspeed sync etc.), zoom settings and flash bracketing mode, can be set via the camera menu.
