Canon RS-80N3 Remote Switch
An 80 cm remote release for EOS cameras featuring an N3-type socket. Two-stage control button behaves in the same way as your camera's shutter release, activating AF on a half-press. The switch also features a lock allowing you to lock the shutter button down for long exposure times or unattended continuous shooting.
