Canon RS-60E3 Remote Cable Switch
Compact remote switch with a 60cm cable replicating all functions of the camera's shutter release button.
An 60cm remote release for EOS cameras featuring an E3-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.
