Resolution of the D800E

How is the outstanding resolution of the D800E achieved?

With normal digital SLR cameras such as the D800, light coming through the lens is separated using a low-pass filter to reduce moiré and false color. With the D800E, the effects of the low-pass filter are removed, and the light is received by the image sensor at a single point, achieving higher-resolution images.

Ordinary OLPF: D800

The original light and light separated in horizontal direction with the low-pass filter 1 are transmitted through the low-pass filter 2 with the wavelengths unchanged. The original light is transmitted as it is, and light separated with the low-pass filter 1 changes only direction vertically (two points are maintained). By converting polarized light into circularly polarized light with the wave plate, two points are divided into four points.

OLPF (effects removed): D800E

By employing optical glass, the original light and the light separated in a vertical direction with low-pass filter 1 is transmitted through low-pass filter 2 with the same optical path length. The low-pass filter 2 changes the direction of the separated light to the opposite side to revert to the original optical path, and the combined light is transmitted to the image sensor as a single point.
