Nikon 1 series
The Nikon 1 series is a line of mirrorless interchangeable lens cameras from Nikon, originally announced on 21 September 2011. The cameras utilized Nikon 1-mount lenses, and featured 1" CX format sensors. The FT-1 adapter was available, which allowed Nikon 1 users to mount nearly all Nikon F-mount lenses, with significant limitations on non-autofocus lenses and autofocus lenses without an internal focusing motor.
Nikon discontinued the Nikon 1 series in July 2018 and launched the mirrorless -series cameras later that year, using full-frame sensors and a new Nikon Z-mount line of lenses. The Nikon Z7 and Nikon Z6 were the first two models. As of 2024, the Nikon Z-series also has largely replaced Nikon's D-series DSLRs with APS-C and full-frame sensors.
