The D810A is an ultra high-definition model that boasts the best image quality in the history of Nikon digital SLR cameras with an effective pixel count of 36.3-million pixels, a Nikon FX-format CMOS sensor with no optical low-pass filter, and the latest image-processing engine, EXPEED 4. It makes the most of the incredible rendering capabilities of the D810, while utilizing an optical filter adopted to enable beautiful reproduction of vivid reds in images of nebulae that emit H-alpha light , something very difficult with run-of-the-mill digital SLR cameras. The optical filter on the front surface of the image sensor is capable of four times greater transmission of H-alpha light than is that used with the D810. This enables clear and vivid reproduction of the strong red H-alpha light emitted by nebulae and galaxies.
