Here is the Swedish Chameleon HDSLR rig. This is one crazy looking rig. However it also has a ton of features and options. I could not get too much from the website. Here is a rip from them about the Swedish Chameleon Rig Large. The SC Large kit is just under 2K US. Click to watch the demo video.
“SC:Large converts your DSLR to a comfortable shoulder camera, including follow focus and a well-placed start/stop button. It also counteracts the weight of the DSLR camera with a back-rod + waist strap which removes all weight from your arms without adding unnecessary weight. Everything comes in a shock-, dust- and moisture-resistant case with custom foam insert.”
