Nikon 1-mount

The 1-mount was first introduced on the Nikon 1 series in 2011, and features a bayonet mount.

The FT1 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.

[2] It further mounts Pre-AI, AI, AI-S and E lenses without metering as well as lenses which jut out the F-mount (needing mirror lock-up on cameras with mirror).

[4][5] These lenses have an in-lens motor to operate the focal length control, aimed at making smooth zooms during videography.

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.
