The Dot Line eTTL Cord w/1/4x20 Tripod Mount Thread f/Canon (0.5 m) acts like an extension cord. Providing up to 0.5 m (1.64') of distance between the camera and the flash, the cord removes the flash from the camera's hot-shoe, allowing it to be mounted elsewhere, such as on a light stand or bracket. This way, the light is less directional and blunt as the flash's output path no longer so closely matches the camera's optical path. This cord features a 1/4 x 20 tripod mounting thread on the flash shoe and is designed to be used with flash brackets. It fits the Canon eTTL / eTTL2 / through-the-lens flash.
