OConnor O-Box WM Mattebox System

The OConnor O-Box WM Mattebox System is a two-stage mattebox designed around the 16:9 format full-size sensor. As a wide-angle system, it can accommodate lenses up to 18mm. It can also accept up to three filters: two in top-loading filter frames (two 4x4 and two 4x5.65 frames are included). A third 138mm round filter can fit in the bellows (optional, sold separately).

Due to its rugged construction, the sunshade is both impact-resistant and lightweight. Additionally, the O-Box is conveniently designed to work perfectly with the Oconnor O-Grips handgrips. The O-Grips can be attached at the 3/8" interfaces on the left, right, and bottom center of the O-Box.

OConnor offers an easy 2-part solution to adapt the mattebox to either 15mm or 19mm studio rods. The LWS bracket included with the mattebox is simply removed via 2 Allen screws (3mm Allen / Hex key) and the unit is then replaced with either part #C1243-1118 for Studio 19mm rods or #C1243-1119 for the offset Studio 15mm rods (studio adapters are sold separately). The OConnor adapter then interfaces with the O-Grips' 3-standard rod bridge #C1244-1002 (not included) for studio-based rod support. This solution provides a total of 6 mounting points for O-Grips (sold separately), while saving valuable rod space.

The O-Box is the first commercially produced mattebox to have integrated handgrip interfaces. While traditionally operators have used the sunshade as a handle, this precarious handling is remedied by OConnor’s O-Grips that can be conveniently attached directly to the O-Box support cage in three locations: camera left, right or bottom center. The bottom center position is particularly useful for small setups such as HDSLR cameras when the O-Grips turn into a pistol-style grip for the operator’s right hand while the follow focus handwheel is in their left.
