The PocketWizard 1' Remote Camera Cable & Pre-Trigger Adapter Kit from B&H is designed for use with Canon, Hasselblad, Bronica, and Contax cameras. The CM-E3-ACC-1 Pre-Trigger Remote Cable is designed for connecting a PlusX, Plus III, FlexTT5, or MultiMAX with ACC port radios to a Canon E3 remote terminal or sub miniphone (3/32" or 2.5 mm). This special remote shutter release cable functions in the same way as previous-generation pre-trigger cables, and controls both the half-press and full-press functions 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. Using a CM-E3-ACC cable with a MSMM Adapter will provide the same function as a CM-E3 cable. But using a CM-E3-ACC cable with a PTMM Adapter will provide the same function as a CM-E3-P cable.
The MSMM Miniphone Adapter is designed for adapting an -ACC stereo miniphone remote camera cable to a mono miniphone cable. It can be used with a Plus II or older MultiMAX top port.
