For a small video production with a telephoto lens on the Canon R (on a tripod), I needed an adapter for the DJI Osmo Pocket to be able to film the wide shot at the same time.
I found a solution on Cults3D at User “3D-Designs”, which unfortunately didn't fit my cold shoe. So I customized it.
The author remixed this model.
I customised the foot for my camera.
