Genustech GWMC Matte Box, Clip-On

The GWMC gives a wide-angle setup two filter stages instead of one: a fixed 4x4 tray for a filter that stays in place, and a second 4x4 tray that rotates the full 360 degrees with friction adjustment and audible clicks every 90 degrees. Both trays remove from the top or the bottom, and the box ships with a GAR82 adapter ring included.

It clips onto lenses from 58mm to 86mm and is built light enough to avoid adding drag to a DSLR or camcorder rig, with a shape designed to minimize the vignetting risk that wide-angle glass creates on a clip-on box.
