Nikon’s 18mm f/2.8 mirrorless DX lens patent

Nikon 18mm f2.8 DX lens patent

I want to mention again patent application 20110080659 filed by Nikon on September 30th, 2010 for a 18mm f/2.8 DX lens (28mm equivalent) because I think this could be the lens used in their upcoming high-end APS-C compact camera. As I already mentioned back in 2011 when I covered this patent, this lens is not designed for F-mount – the […]

Nikon’s patent for a hybrid, semi-transparent LCD screen


Nikon filed a patent (2012-257100) in Japan for a semi-transparent, see-through, rotating LCD screen. The idea behind this patent is to overlay the camera’s live view on a semi-transparent LCD display. This will allow a better tracking of fast moving objects and the photographer will be able to observe the entire scene beyond what is being shown in […]

Nikkor 18-55mm f3.5-5.6 lens patent

Nikon filed a patent (2012-220827) in Japan for a Nikkor 18-55mm f/3.5-5.6 lens. Egami reports that this lens was designed for a mirrroless APS-C based camera. 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. The sensor is attached to the camera’s back panel and by replacing it, you will be able to get […]
