Nikon patents for illuminated F-mount, duplicated electronic mount contacts and hybrid viewfinder

Nikon LED mount lighting patent

Nikon filed patent application 2013-57757 that will make changing camera lenses in the dark easier by illuminating the mount/lens. The implemented LED light source in the camera will transmit light to the mount and lens via an optical path located above the optical elements.

Nikon duplicated electronic mount contacts

Another patent application (2013-58840) describes duplicated electronic mount contacts that will ensure communication between the lens and the body even if one of the contact sets is damaged/dirty.

Nikon hybrid viewfinder patent

Nikon patent 2013-54232 is for technology that instantly switches between an optical (OVF) and an electronic viewfinder (EVF) - something similar to the hybrid viewfinder inside the Fuji X100.
