This 2-Pin LEMO-Type to 3-Pin Fischer-Type Cable from Tilta is used to power accessories with a 2-pin LEMO-type power input port from your camera with a 3-pin Fischer power port. The connectors are standard for the cine and digital cine industry, and they feature a locking collar with a push/pull design to make sure the power to your accessory is uninterrupted, as the cables cannot accidentally fall out of the ports.
