I was talking with Tim at indisystem about this earlier this week. When I figure it out, I will post something. He mentioned that he might get a 46mm step up for their mattebox and mail it to me. I will follow up with him.
I use the 20mm pancake and indiesystem followfocus, I just use a single french flag on an adjustable arm to keep light off the lens, I find my mattebox just gets in the way. less is more.
Thanks for that. Ummmm so is it possible though.......was thinking some sort or diy/step up ring configuration could give a lil space between the mattebox and ff. Keep in mind i am thinking a smaller type mattebox
LOL.......well i just figured i could save a few hundred as opposed to getting the tokina......heard the tokina is great can be a lil soft in the edges and gives barrel distortion.........dorry if my terminology is wrong.....makes edge lines bend.....anyways what a conundrum...lol.
Follow focus and matte box are mechanical devices. The Lumix 20mm pancake is an electronic gizmo that can only simulate the behavior of a mechanical device. If you want to assemble a follow focus/matte box rig with a fast 20mm lens, this one has the mechanical controls you need:
