Review on Upgrade Your Filmmaking Setup With The JTZ DP30 Cine Lens Matte Box & Rod Rail Rig Compatible With Sony, RED, Canon, Blackmagic, And Panasonic Cameras! by Darius Newberry

I have this on my rig with a GH5. I did a lot of research on matte boxes. I didn't want to pay more than about $500.This is well made and solid. Happy with it. Couple things to consider: There is not a lot of up/down movement, with 15MM rods, the center of your lens should be about 85 MM from the rods. If you are way off from 85MM, your lens will not fit. Works best with carbon fiber rods. I tried with metal rods and it was difficult to get onto rails. Like the top handle, swing away and the flags.
