This Fotodiox lens mount adapter is made with high standard precision. The all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences. It allows all T-mount system (42mm x 0.75 thread Mount) lenses to fit on the Nikon 1-Series camera bodies. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You must shoot in manual shooting mode. Infinity focusing is guaranteed.Compatible Lens Systems:Leica M lens, CL lens, Ernst Leitz Canada's ELCAN lens, Konica Hexar RF lens, and Minolta CL, CLE Rokkor Lens, Voigtländer lenses With the Bessa T, R2, R2A, R3A, R4A, R2M, R3M and R4M, Rollei 35 RF, Zeiss Ikon rangefinderCompatible CamerasNikon 1 Mirrorless Cameras (Including, but not limited to):S2, J4, V3, AW1, S1, J3, V2, J2, V1, J1The product pictured may have slight differences in appearance from the actual product such as color, font style, and/or other cosmetic changes due to improvements in design.Note: The camera must be in manual shooting mode and the focus selector set to manual for the camera to work with the adapter.
