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 […]
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 […]
The first patent application is rather unusual – it describes a Nikon 100mm f/2.5 medium format lens. As far as I can remember, this is the first medium format lens patent from Nikon.
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 […]
Nikon filed another patent in Japan for a 50mm f/1.2 and 60mm f/1.2 lenses. The 50mm f/1.2 lens (and different variations of it) has been the most patented Nikkor lens in the past few years – here are some of the related patents filed in the past: 58mm f/1.2 (and another one) 50mm f/1.2 (and another one) 58mm […]
Nikon patent application 20130182173 is for combining/stacking a dedicated AF and imaging sensors without losing any light (in theory): “The idea is simple: RGB color filter array does not use roughly 2/3 of the light in each pixel, why not use the lost light by a complementary-colored organic AF sensor stacked on top on the […]
Nikon filed a paten 2013-134682t in Japan for a new 3-point camera hand grip strap. Similar products already exists from various manufacturers, including the Nikon AH-4.
The latest Nikon patents filed in Japan: in order to prevent camera overheating, one of the patents describes a removable/interchangeable heat storage that will absorb the heat produced by the sensor (Peltier effect). The heat storage can be replaced, similar to to the camera’s battery and memory card. This will be especially helpful during long video recordings. One of the related […]
