This 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 –ACC cable allows a compatible PocketWizard radio to independently control both half-press and full-press functions.
Cable lengths: 3' (91.5 cm) and 1' (30 cm)
From: 1/8" (3.5 mm) stereo miniphone
To: Nikon MC-DC2 remote shutter release terminal
Int'l #: N-MCDC2-ACC, N-MCDC2-ACC-1
US #: 802-455, 802-503
Compatible with the following radios:
PlusX: Use this cable with the PlusX to trigger the camera.
Plus III: Use this cable with the Plus III’s exclusive 2-stage trigger to wake-up or focus your remote camera just like using the camera’s shutter release button.
FlexTT5: This cable is required for auto-relay mode with E-TTL, or other remote triggering with the FlexTT5. Learn more here. You can use a N-MCDC2–P (-P) Pre-Trigger cable or N-MCDC2 Standard Cable with a FlexTT5, but your remote camera will not be able to relay an E-TTL signal to Speedlites. The FlexTT5 does not support the 2-stage trigger function.
MultiMAX with –ACC port: Enable a remote zone with your hand-held MultiMAX, and your remote MultiMAX will wake up its remote camera with this cable. As long as the zone is turned on, the remote camera will stay awake and respond more quickly and consistently, but also consume the camera's batteries much more quickly. When the remote zone is disabled, the camera will enter its normal sleep modes. The MultiMAX does not support the 2-stage trigger function.
