Micro Studio Camera 4K

Can anyone confirm if the power socket on the camera is a 2.1 or 2.5mm socket.
I am looking at getting a power only connector for the camera made and can'f find anywhere if it is a 2.1 or 2.5 as everything i read says 2.1/2.5

Anyone able to help?

According to BM,

The plug sizes is:

9.5mm long (plug length)
5.5 mm wide (plug width)
2.1/2.5 mm (center pin)

So either a 2.1 or 2.5 center pin should work, the socket accepts both.
This is the same size plug used on the BMCC, BMPC, Studio and Micro Cameras. The Pocket camera had a smaller plug. Also, the Mini Converters use the same plug. Any adapter cord listed for a BMCC will work with the Micro Studio camera power connector on the DB-15 breakout dongle plug.
