I'm trying to build a specific rig that attaches to a camera. This rig must then be able to 'snap on' to another rig which will be attached to a jib crane. So what I need help with is what to use as the connector. It needs to attach/detach easily and quickly and smoothly (so it looks seamless on the camera footage) also it needs to tight and secure so the camera doesn't wobble much. An electromagnet was my first thought but then I thought that would likely screw up the camera. Thanks for any help!
