Most DSLR and SLR cameras can be triggered remotely using a shutter release cable. Unfortunately, the connectors used for the external release have rather different shapes. We have 13 types of cables to support more than 300 camera models. Refer to the pairing tabs to find out which cable is right for your camera. When you get a new camera, you only need a new camera cable to keep using Pluto Trigger!
Since there is IR remote function designed into Pluto Trigger, you may still be able to trigger your camera even without a camera cable.

The trigger end of the cable has a 2.5mm plug, not 3.5mm.
