Adapters are attached to the camera body using four M3 (3 mm metric)
screws. Threaded holes on the camera body are placed on the corners of
52 mm square. Custom adapters can be made upon request.
G2 and G3 cameras use smaller 44 mm threaded hole square on the camera
head for mounting adapters, so adapters for G2/G3 series and G4 series are
not compatible.
