Did not always want to use the big dual grip from feiyu, so I made this adapter to mount the SmallRig handle to the single hand grip.
The adapter itself is clamped to the gimbal grip with a GoPro screw. Fits tight, but is also easy to mount and to remove. It's strong enough to hold a monitor (in this case Lilliput a7s) and even the gimbal with a Sony a6300 in a cage. I have no doubt it would hold the max 2.5kg of camera gear the gimbal is able to carry.
