NOTE:  As of July 2013, we've replaced all -P cables with a Pre-Trigger Mono Miniphone (PTMM) Adapter.  This adapter works with the CM-E3-ACC to convert it from a -ACC cable to a Pre-Trigger (-P) cable for pre-releasing your shutter.  So if you are looking for a CM-E3-P cable and cannot find one, ask your local or online retailer for a CM-E3-ACC cable and a PTMM Adapter and you'll be good to go. 

If you are confused about what cable you need, either read the
Compatibility and Description information below or visit our cable finder.

From: 1/8" (3.5 mm) mono miniphone

PocketWizard Compatibility:         

· Plus II
· MultiMAX with no ACC port
· For the PlusX, Plus III, MultiMAX with ACC port, or FlexTT5 radios, use the CM-E3-ACC.

Description:  This cable contains a Pre-Trigger switch.  When enabled, the camera behaves as if the camera's shutter release button were held half-pressed continuously. This makes the camera respond more quickly and consistently, but also consumes the camera's batteries much more quickly. When disabled, this cable functions identically to the CM-E3.

This Pre-Trigger (CM-E3–P) cable works with most PocketWizard radios. This pre-trigger cable has a switch that allows you to toggle half-press on or off at the camera position, but not remotely.

A CM-E3 Standard Cable works with most PocketWizard radios but has no half-press control, and is for basic remote triggering only.

A –ACC (CM-E3-ACC) cable allows a compatible PocketWizard radio to independently control both half-press and full-press functions, as well as relay E-TTL signals to compatible flashes when using FlexTT5s.

All cables are now packaged in a environmental friendly cardboard box with rececyled white labels showing both ends of the cable as well as compatibility list. This replaces our old packaging of a zipped bag packaging.

Compatible with the following radios:

Plus II: Use this cable to remotely fire your camera.

Plus III: This cable can remotely fire your camera and control half-press function at the camera’s position.  Use a CM-E3–ACC cable for best results and to have half-press capability from the transmitting radio.

MultiMAX with no –ACC port: Use this cable to remotely fire your camera and control half-press function at the camera’s position.

MultiMAX with –ACC port: This cable can remotely fire your camera but cannot wake up the camera in a remote zone.  Use a CM-E3–ACC cable for best results

FlexTT5: This cable can remotely fire your camera and control half-press function at the camera’s position, but your remote camera will not be able to relay an E-TTL signal to Speedlites.  Use a CM-E3–ACC cable for best results.  Learn more here
