If you want to mount a medium format camera on a panoramic head, you better have some serious kit that can support weights beyond 2kg. The Nodalninja has no problem to carry my Mamiya ZD plus 105-200 or 24mm lens (which adds up to 3kg). Here some images of this setup. The tripod looks a bit flimsy but it stands like a rock (and it has a reasonable weight) and you dont need to remind me of the dangling shoulder strap which adds to blur !
