Dedicated to the Canon EOS 77D and Rebel T7i DSLRs, this BR-E1 Wireless Remote Control allows you to wirelessly release your camera's shutter via Bluetooth from within a 16' operating range. It has low power consumption and requires no line of sight to the camera, and is also compatible with the PZ-E1 Power Zoom Adapter for remotely adjusting zoom position and movement of the EF-S 18-135mm f/3.5-5.6 IS USM lens.
