Camera Release Cables for different cameras
Release cables for remote triggering a camera are standardized. Those cables have a 2.5mm TRS plug on the one side, which will fit into one of the camera jacks on the LRT PRO Timer and a specific connector for your camera release port on the other side.
Carefully choose the right product for your camera from the selector box. Such a cable should not cost more than 10US$ / 10€. I’d recommend to buy two, in order to always carry one spare cable with you, just in case that one of them breaks.
