The Quantum's TriggerSmart UK70 Camera Trigger Cable is the standard cable that connects your camera to the UK1 TriggerSmart Controller. This is an included cable as part of the TriggerSmart Kit but can also be purchased separately for multiple camera set-ups with the TriggerSmart system. The cable has 2.5mm jacks on both ends and is compatible with select Canon, Contax, Pentax and Samsung cameras. For other cameras, a different dedicated cable must be purchased. The cable is an 18" coiled cable, when not stretched.
