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

Pin It

Pin It

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 […]
