Nikon introduced the Nikon D850 in 2017 with a 45.7-megapixel backside-illuminated (BSI) Nikon-specified/Sony-designed/TowerJazz manufactured sensor. The Nikon D850 is regarded as one of Nikon’s best cameras and continues to range at the top of consumer DSLRs.
Full disclosure: I’m the president of MaxMax.com, which makes the monochrome D850 (D850M), and this article is blatantly self-promoting. That being said, everything happens to be true.
My business MaxMax has been converting a limited range of cameras to monochrome since 2009. After being encouraged by The Desert Fireball Network of Curtin University in Australia to convert a Nikon D850 to monochrome, MaxMax decided to try it.
