I got the chance to put my EPIC-M on an Element Technica Mantis rig yesterday and I was stoked! I can't get over how lightweight the EPIC set-up is overall and with the Mantis it all just clicked for me.
Personally, I need a hand-held rig that can balance on my shoulder. I just can't have my arms giving out in the middle of a long documentary take (20 minutes plus) and this has happened more than once using various front heavy rigs born from the DSLR world. With the EPIC/Mantis combination, I've found my doc set-up. The camera was balanced, lightweight and just felt right. The set-up could probably be another 4 pounds lighter as we had a large 150w battery hanging off the back and a monitor in place of an EVF - but even with that it was awesome. I will probably lose the two-stage extension to put the grips closer to rods.
We also tried mounting the RED TOUCH LCD as the operator monitor (so a lone operator could control without an AC) and this worked as well. Add a hood to the LCD touch and you're off shooting solo.
The set-up includes:
18mm Zeiss Superspeed
FMJ Top Plate
ET Shim Plate
ET Hybrid Base plate (set-up w 15mm rods)
ET Lightweight Rod Bracket
ARRI MMB-1 (attached to lightweight rods)
ET IDX Battery Plate & Cable (custom made 4")
Batteries4Broadcast 150w RED Battery
TVLogic 5.6" Monitor (in lieu of EVF)
Most of our testing was done inside but we caught some sun and took some pics outside of the set-up. Here are some pics to check out.
