The 13369-S is a special remote shutter release cable called a pre-trigger cable. A pre-trigger cable controls both the half-press and full-press function of your remote camera’s shutter release. When a camera is “pre-triggered”, it is like holding your camera’s shutter release button in the half-pressed or metering / focusing position.
This cable allows a compatible PocketWizard radio to independently control both half-press and full-press functions.
From 1/8″ (3.5 mm) stereo miniphone to Sony’s multi/micro USB port and USB power source. Cable connects remote camera to a PocketWizard for remote triggering and to a battery pack to power the camera. Cable Length: 3′ (91 cm) straight. Compatible with all PocketWizard radios. For Sony’s Alpha cameras and others with Sony’s multi/micro USB port.
