You guys should make this but as a variable polarizer (cpl) filter (takes up two trays) that way, we can have a variable ND filter (takes up two trays), and a black mist filter stacked for filming moving water with the sku 3641 matte box. Right now, I will just have to work with three trays but would happily buy two more and the variable polarizer if you guys got this going. Also, can you guys please make a 15mm rod swing away mount vs the existing 15mm hard mount included. I would also buy that.

How do you mount a motor to operate the vnd filter? ideally it would be attaching to the mattebox rather than to the camera cage? Other companies seem to have achieved this for thier products is there any kind of motor mount that can position a motor in a suitable postion?
