Nikon Z is a full-frame mirrorless camera system. Nikon announced in 2018 an aggressive competitor to the mirrorless interchangeable lens market dominated by Sony, Fujifilm, Panasonic and Olympus. Having focused primarily on DSLR cameras in the post-film era, Nikon’s only mirrorless attempt was the now discontinued Nikon N1. The Nikon Z7 and Nikon Z6 are the first models of full-frame mirrorless cameras. The Nikon Z7 features a 42 megapixel sensor and the Z6 features a 24 megapixel sensor.
