Can this camera plate be the only one you need?? 

I use the f38 - kinda discovered by accident, but it's the closest thing to universal I can get. I wanted something that would let me go from gimbal to tripod quickly.

I have had Peak Design plates on all my Sonys for years now. This is a nonissue.

How can attach the SmallRig VB99 Mini V-Mount Battery (99Wh) without adding any parts on the two rods and plug it to the Dony fx6
