The Wooden Camera Zip Box Pro 4 x 5.65" Matte Box in its swing-away configuration mounts on 15mm LWS support rods (rods not included) and has a rear opening of 114mm. Rather than swapping clamp-on backs, it ships with interchangeable reduction rings in 110, 104, 95, 87 and 80mm sizes that seat tightly against the lens barrel to prevent light leaking in around the back and flaring the filters, plus a universal cloth donut for non-standard or moving lens fronts and for use when tilting the matte box — and, because the matte box itself is swing-away, it can be swung clear of the lens as a whole unit, adjusting 4mm above and 4mm below lens centre using the same two side screws that control tilt. It still accepts up to three 4 x 5.65" (Panavision-style) filters without the need for filter trays, with up to two of those filters able to tilt independently to help move reflections out of the picture area. It ships complete with a carbon-fibre top flag.
