Seems there are more than a few companies that are putting a number of rigs together for the latest cameras on the market. Having choices and solutions as to which camera rig best suits your shooting style is a very good position for us to be in. KCW technica have shown off some MRK builds with the RED Epic & Scarlet cameras. So the guys at KCW technica have put the MRK Stage 1 Crank and MRK Stage 1 Sub Machine rigs up on their blog with more rig combos to follow.
See KCW technica for more rigs.
