Nikon 1-mount
Digital camera lens mount
From Wikipedia, the free encyclopedia
The Nikon 1-mount is a type of interchangeable lens mount developed by Nikon for its Nikon CX format mirrorless interchangeable-lens cameras. The 1-mount was first introduced on the Nikon 1 series in 2011, and features a three-lug bayonet mount with a 40 mm throat and a flange to focal plane distance of 17 mm.

Cameras
The Nikon 1 series of mirrorless interchangeable lens cameras was originally announced on 21 September 2011[2] with two cameras, the Nikon 1 V1 and the Nikon 1 J1. It grew over the following seven years to have a total of 11 cameras. Nikon discontinued the series in July 2018,[3] when the Nikon Z-mount was introduced.

Power zoom lenses
These lenses have an in-lens motor to operate the focal length control, aimed at making smooth zooms during videography.

All-weather lens
Lenses are optically identical to their non-sealed counterparts and use the same bayonet, but have an extended flange to ensure a watertight seal with the Nikon 1 AW1 body.[16]

Nikon 1-mount adapter to use F-mount lenses
Nikon SLR cameras, both film and digital, have used the Nikon F-mount with its 44 mm diameter since 1959. The 1-mount has a 40 mm diameter. The FT-1 lens adapter allows many F-mount lenses to be used on 1-mount cameras.[19] The FT-1 adds 29.5 mm to the length of the attached lens, which is the difference in flange distance between the Nikon F-mount (46.5 mm) and the 1-mount (17 mm). When used with the FT-1, F-mount lenses have a 2.7x crop factor, e.g., a 300mm lens acts like an 800mm lens.[20]
An adapter is attached to a powered-off camera in the same manner as a lens. Once it is attached, the F-mount lens can then be attached to the adapter.[21]
The mount adapter provided by Nikon to support F-mount lenses on their 1-mount mirrorless cameras is:
- Nikon FT-1: The FT-1 supports the use of all F-mount lenses especially with integrated autofocus motor. The FT-1 adapter mounts and meters with all AI-P, AF, AF-S, D and G lenses and compatibles providing autofocus with all lenses with integrated autofocus motor.[22] It further mounts Pre-AI, AI, AI-S and E lenses without metering as well as lenses which jut out the F-mount. Although not recommended,[19] it can be used with teleconverters for extreme telephotos.[23][24]

Future lenses
At the Nikon 1 launch in October 2011, Nikon showcased seven prototype lenses.[29] As of October 2012, five of those lenses had been produced.
Due to its introduction of the Nikon Z-mount, Nikon discontinued the Nikon 1 line in 2018, including cancelling any future lens releases.[30]
