Rhino Cam (Click here) created a sort of medium format adapter that uses a Sony NEX camera to make a scan of the image created through a classic medium format camera. In short, you put the adapter between the NEX camera and the Pentax 645 or Mamiya 645 or Hasselblad V medium format lens. The NEX camera moves to take multiple shots from the medium format area (62,4 x 46,8mm). Than you just have to stick the images together to have your 140+ megapixel photo. It’s a sort of “panoramic mode” for medium format cameras :)
Yep, it’s a bit like having a digital back but of course this solution works on still objects only! It’s priced at $499 and you can order it here: Fotodioxpro.com.
