Here's a question I have been trying to answer. I LOVE the Action Prducts audio solution. If I mount red's quick release camera plate on the bottom of the 15mm audio plate from viewfactor, and then use red's epic 19mm Quick release baseplate, will the 19mm spacing be off? I'm assuming it would, but this would be the ultimate rig. Does this make sense?
Basically from top to bottom would be: camera, AP audio plate, Red epic camera plate, Red quick release dovetail platform w/ 19mm mounts.
