Sans Mirror  

If you need a CX lens repaired, particularly for the common internal breakage problem, a repair service in Taiwan might be able to help. 

The now discontinued Nikon 1 cameras use CX mount lenses. CX mount lenses have a 2.7x angle of view crop compared to 35mm and FX lenses. CX mount lenses can only be used on Nikon 1 cameras—they do not work with Nikon's DSLR cameras (DX or FX) or Z System mirrorless cameras. 

At the introduction of the Nikon 1 cameras, four lenses were announced (10mm f/2.8, 10-30mm f/3.5-5.6, 10-100mm f/4.5-5.6, and 30-110mm f/3.8-5.6). After that, Nikon added five lenses (11-27.5mm f/3.5-5.6, 18.5mm f/1.8, 32mm f/1.2, 6.7-13mm f/3.5-5.6, and a 10-100mm f/4-5.6), and AW variations of two.

Finally, note that Nikon offers an FT-1 adapter that allows you to mount F-mount (DX or FX) Nikon lenses on the Nikon 1 bodies. However, there are some limitations you need to be aware of. See Nikon’s page listing those FT-1 limitations.
