I have an older Cavision mattebox that has been modified. I cut the front edge of the sunshade off to aid with wider lenses. It uses 4X4 filters - one tray stationary, the other rotates (although not too smoothly). I'm including two trays and 90mm and 85mm inserts. Also an adapter to go from 72mm to 85mm. Rail mount as well. This thing is used but still has a lot of life left. Want a cheap way to use 4X4 filters - this is it. $75 + shipping. Lower 48 only.
