Nikon sues Polaroid/Sakar for mirrorless camera design patent and trade dress infringement

Do you remember the Android based Polaroid IM1836 interchangeable lens camera that looked very much like the Nikon 1 J1/J2 models? Even the 30-110mm lens looked identical to the Nikkor 1 30-110mm f/3.8-5.6. Nikon also thinks that Sakar/Polaroid ripped their Nikon 1 camera design and filed today a lawsuit in the U.S. for design patent and trade dress infringement. Here […]

Are those the new Nikon 1 mirrorless cameras?

      I guess this week will be dominated by patents and guests posts… First, few patents (USD682338, USD684203 and USD683779) that show different Nikon 1 camera designs. Could those be the new set of Nikon 1 cameras that will be announced in the next few months? All three patents were filed on March 6th, 2012. Maybe the […]

Another Nikon patent for a 300mm f/4 lens with diffractive optical element (DOE)

Nikon filed a patent in Japan for a 300mm lens with a diffractive optical element  (Canon has a good DOE explanation on their website). The exact aperture was not specified, but I am pretty sure it’s f/4 (see this patent from last year). This is an interesting development because I expect Nikon to announce a new […]

Nikon’s patent for electrically controlled optical low-pass filter

Nikon filed a patent in Japan (2013-156379) for electrically turning ON or OFF the optical low-pass (OLPF) a.k.a. anti-aliasing (AA) filter. Currently the Nikon D800E and D7100 do not have AA filters on their sensors. Nikon filed a similar patent back in 2011 which offered a mechanical ON/OFF solution. Another patent from last year suggested adding the OLPF inside the lens. Detailed description […]
