The 33' Vello Off-Camera TTL Flash Cord provides creative photographers with the ability to remotely fire Canon flashes with E-TTL / E-TTL II capabilities. Removing the flash from the camera's hot shoe allows the photographer to create unique and dramatic lighting styles that are not possible with a traditional shoe-mounted strobe. This straight cord measures 33', which will accommodate users who want to work with a flash mounted to a light stand or placed a distance away from the camera.. Also, off-camera lighting reduces the harsh shadows commonly encountered with direct on-camera flashes and gives your photographs a more natural look.
