The Vocas MB-436 Matte Box Kit works with any camera with 15mm rail support. It includes MB-436 Matte Box, 143mm Flexible Donut Adapter Ring, and 15mm LW Swing Away Bracket.
The black MB-436 Clip-On 4 x 5.65" Matte Box from Vocas provides a lightweight, versatile solution for stacking up to three filters on your video rig. It incorporates one fixed 4 x 5.65" filter holder within its hood, one rotatable rear stage for filters up to 4 x 5.65", and one fixed rear stage for up to 4 x 5.65" filters. It comes with two 4 x 4/4 x 5.65" combo filter frames and one compact top flag. It also has built-in top and bottom eyebrows for guarding against flares without adding external mattes.
The MB-436 clamps directly onto lenses with a maximum 143mm outside diameter and can be used with smaller diameter lenses via separately available step-down adapters. The included top flag (eyebrow) attaches to a lockable hinge along on top of matte box, and similar hinges for optional side flags are built into each side of the matte box hood. Use the MB-436 with the separately available swing-away bracket for quick and easy lens changes.
This is a 143mm Flexible Donut Adapter Ring for the Vocas MB-435 and MB-455 matte boxes. It supports a max lens diameter of 133mm and is also compatible with round 138mm filters. It comes with 4 soft rubber donut rings (112mm, 100mm, 75mm, 50mm).
The Vocas 15mm LW Swing Away Bracket attaches directly to the rear of the MB-430 Matte Box and allows the user to mount the matte box onto 15mm lightweight rods. When the red knob of this swing away bracket is twisted, the matte box is released from its locked position, allowing the user to swing it away from the lens. This swing away bracket can also be fitted with a 19mm rod adapter, allowing the MB-430 Matte Box to be used on 19mm rods.
