This is probably the most interesting Nikon patent since I started my coverage in 2008: last year Nikon filed a patent (2012-242615) in Japan for a digital back that will transform a 35mm film SLR camera into a DSLR. The sensor is attached to the camera's back panel and by replacing it, you will be able to get the digital solution many have dreamed for years (digital FM2 anyone?). Since the back panel is detachable, the switch between film and digital SLR will be simple and fast. The patent application is current - it was filed on May 19, 2011 and was published a week ago (December 10, 2012). In the patent Nikon describes a mechanism for adjusting/fine-tuning the flange distance with a screw located on the digital back. Here are few paragraphs from the actual patent application I copied directly from the Japanese IPDL database (machine translated):
The camera back exchange type camera which images the object image acquired by the photographing optical system by the side of a camera body, and obtains electronic image data is known by replacing with the rear lid with which the camera body was equipped, and equipping a camera body with the camera back having an image sensor.
In the camera back of the description to this Patent document 1, when the moving mechanism to which the position of an image sensor is moved, and the position detection sensor which detects the position of an image sensor are provided and a moving mechanism moves an image sensor based on the output of a position detection sensor, The image sensor to the photographing optical system by the side of a camera body is positioned.

Is this similar to Leica R8/9? http://www.dpreview.com/news/2003/6/25/leicadigitalr9![]()

Well just read that Nikon also used the Kodak digital back, so its quite similar.
