I am selling my RhinoCam. I am assuming anyone looking at this already knows what it is, but for a quick overview, you can mount a sony nex on the back of this and there is an adapter for pentax 645 lenses on the front. It is possible to buy other adapters to use Hasselblad V or Mamiya 645. It is in pristine condition, comes with original case. I am asking $325, shipping is free in the continental US. If you are outside of the US let me know and I can figure out what they shipping will be. You can contact me here on getdpi or at my email [email protected]
