The IDX A-CA74E Shoulder Adapter is an expandable/collapsible starting point of a handheld shoulder rig. It expands to accept the attachment of ENG/EFP cameras and it is highly configurable into a complete rig with the addition of optional accessories, such as IDX's A-HG74 Hand Grip Adapter. But what's distinguishable in this device, in regards to its being a rig, is its efficient support for batteries. Out of the box, it features as part of its design a plate for 12V IDX ENDURA batteries.
However, out of the box this rig is only a starting point towards a complete rig, featuring native support only for a camera and a battery. You can outfit it to your needs though. You can optionally add a P-V212 plate for 12V DC output; a P-V257 for 5 to 7.3V conversion; or a P-V284 for 8.4V compatibility. You can also add a CW-5HD wireless transmission module or ENDURA batteries in PowerLink.
