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 Gregory Rasmussen

Fantastic quality for the price. Every feature you want is included. Even the adapter for wider rail configurations. My only real complaint? The light bag is WAY TOO SMALL! Unable to get the opening over 50mm! Why? Insufficient tensioning twine. I also realize that the filters are designed to be 4"x4". So there will always be some cutoff from the 16x9 framing. BUT! The depth of the sunshade itself is just slightly to short. With the filter holder frames to close. So unless you remove the filter holders - negating that feature - the view is cut off from the sides with full frame lenses of under 21imm. If I had known this. Would have bought the version with rectangular filter holders. Eh - Not a big deal. Will just order the rectangular holder replacements.
