Nikon 9mm F/1.8 Patent for 1 Inch Sensors.
Nikon has filed a patent for a 9mm f/1.8 lens for its one inch sensor cameras. Currently the widest Nikon 1 prime lens is the Nikon 1 NIKKOR 10mm f/2.8 Lens. There is also the Nikon 1 NIKKOR 6.7-13mm f/3.5-5.6 VR Lens, which covers the 9mm range but as a variable lens would be expected to produce lower quality results than a dedicated prime. Neither of these lenses are as fast and currently a f/1.8 aperture is only available for Nikon 1 cameras in the Nikon 1 NIKKOR 18.5mm f/1.8 Lens.
