It will be interesting to see in the next few months if  more similar patents will show up online. I seriously doubt that Nikon will introduce a new mirrorless camera system […]

Nikon patents a digital back for 35mm film SLR cameras

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.

Nikon patent for adapter that can improve AF when using old Nikkor lenses

Nikon filed patent 2012-215769 in Japan for obtaining a high precision focus when attaching an old Nikkor lens to a digital camera (this solution is probably intended for Nikon 1 mirrorless cameras).
