O-Box WM

O-Box WM
Doug Jensen, Producer/Director/Cameraman
The O-Box is built like a tank – yet it is still very lightweight. I have never seen any matte box that even comes close to its ruggedness. It reminds me of something that is built to military specifications

Product Specification

O-Box WM Mattebox System

Famed support maker builds a better Mattebox
Top cinematographers understand the advantages of high-end professional glass filters both for in-camera effects and practical exposure issues. Its about control and that’s why they also understand the benefits of effective light management and flare control that can only be done with a high-end mattebox system including flags and wings. OConnor has painstakingly come up with a solution to intuitively handle filters, and allow configuration freedom to meet just about any shooting situation.

Wide and Mini in one
The OConnor O-Box WM is a two-stage mattebox designed around the 16:9 format full-size sensor. A wide-angle system, it accommodates lenses up to 18mm (and in some cases wider).

15mm Studio and 19mm Studio Solution
OConnor offers an easy 2-part solution to adapt the mattebox to either 15mm or 19mm studio rods. The LWS bracket that comes 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. The OConnor adapter then interfaces with the O-Grips' 3-standard rod bridge #C1244-1002 for studio-based rod support. This solution provides a total of 6 mounting points for O-Grips, while saving valuable rod space.

Meeting industry expectations & beyond
In true OConnor fashion, the O-Box system delivers the expected and more. This precision mechanical device adeptly accepts up to three filters: two in top-loading filter frames (two 4x4" and two 4x5.65" frames are included). The rear frame is rotatable 360 degrees. A third 138mm round filter sleekly fits in the optional bellows ring.

Constructed of OConnor’s proprietary rugged composite, the sunshade is lightweight yet substantially stronger and more impact resistant than existing units. This translates to fewer sunshade replacements arising from the rigors of professional production environments.

Get a Grip on your Mattebox

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.

  • Lightweight, rugged Wide Mini Sunshade of proprietary composite material
  • Two stages; front fixed/ rear rotatable 360 degrees
