I have an 80MP Leaf digital back, that I'm currently selling. I can send you pictures, and information if you are looking for something other than the 380. As someone who spent 3 years looking for the 180 for my Contax 645, it may be a while before a 380 comes up. The Leaf is the same resolution, but it has the ability to rotate, so you don't have to take the DB off of the camera to switch the orientation.
