with the A7s in the M5 I would love to get some more options for fixing 15mm rods back to the top plate that currently only engages with the hot shoe. Anyone got some examples of adapters uses those extra holes in the top plate? Ideally a 2 point fixing to avoid torque pivoting the focus motor.
I'm not sure I completely understand what you're trying to do, but The Top and Bottom Movi plates are interchangeable as far as the Movi connection goes, if that helps. You can get an additional bottom plate with an iris rod adapter to put on top -- but it won't have a built-in Hot Shoe Mount. So then you might need a hot-shoe to 1/4-20 female, so you can bolt on the plate to your A7. Something like this: http://www.bhphotovideo.com/c/product/855425-REG/SHAPE_hsm_Universal_Female_Hot_Shoe.html And a locking washer might help keep it from rotating on you from the torque of the motor.
