I don't know who's to blame, Juicebox for the cable or Blackmagic for the crappy little port. But whatever it was, it took us a whopping 30 minutes to connect that cable to the camera. Navigating the rubber covers is difficult enough, but it doesn't seem to want to connect even though the notches line up. Three of us (all paid, professional professionals) assembled this flimsy thing and still couldn't get it in. We hired a vet to help us with accuracy. I'm not joking. After a while I carefully spread the plugs in the cable a little further and tested the port with another cable. After we connected another cable and I fiddled with it, it fit. I have not turned it off and will never turn it off again.
