I am planning to build up a Shoulder Rig for my GH4. I am pretty close to have all the research done, but there is one thing, that struggles me.

The GH4 will be resting on my shoulder and I have no very nice and easy way to access the main Buttons for setting Expsoure "ISO, Shutter, Iris". I´ve seen an "Handgrip relocator" from Zacuto for the FS700, so you can relocate the Handgrip where ever you want and have still the "One Hand Access".

So my Question would be, if there is some kind of "Third Party Handgrip" or an interesting LANC Solution for the GH4, that i can attach to my normal handgrip?

Thanks
