I have a need for a device which clamps onto the FX/Z top handle and will carry two cable releases so that I can remotely operate the Shot Transition buttons A, B without physically touching the camera etc

Not too shabby please even machined Black Acrylic would be nice.

Does it have to be wired? (cables)? Would wireless get in the way?

Youve got something up your sleeve, eh Dan? :)

No John.
You asked for help and I offered to help. That's all.
