Nikon D5R concept camera

This Nikon D5R camera is a designer’s concept created by Ned Mulka. The idea is to include the mirror, prism and sensor into a rotating element that can reduce the camera size and weight (see this slideshow for a detailed description of this concept).

Please note that  this is only a concept camera that is not associated with Nikon Corporation in any way. As always, I am interested in your opinion and feedback.
