Built For Flight. The PolarPro Basecamp Matte Box Kit is very light for its features set. The aluminum construction supports a design that weighs only 12.7 ounces to keep flight payloads as low as possible. Lightweight is also good news for handheld gimbal users wanting filtration and a top flag.
Lens Compatibility. This mattebox has two modes of mounting. First, clamps are included to attach it to 80, 87, 95, 100, 104, and 110mm lenses, and second, threaded adapters allow it to screw onto 77 or 82mm threaded lens fronts.
Filters. You also get two options of filter type, but they are less universal. The PolarPro Basecamp brand offers proprietary 5.5 × 5.5 in square options or 4.5 in round filters. This rental includes a 2-5 variable ND filter as well as a circular polarizer filter. This product is not compatible with traditional mattebox filters.
