Please consult us before purchase if could not 100% sure about your lens and camera mount. Suitable for: Lens: Canon EF EF-S mount lens Camera: Nikon 1 N1 Series Mirrorless Camera Body(NOT for Nikon DSLRs, e.g. D40 D70 D3100 D3200 D3300 D5100 D5200 D7100 etc.) Note: 'Check lens. Pictures can only be taken when a lens is attached' - Warning Message Appears With a Nikon 1-Series camera (such as the J2), you will need to make sure the camera is in 'Manual' exposure or shooting mode and the focus selection is also set to manual. When in any other mode the camera tries to take control of the lens which is not possible as the adapter does not have any contact with the camera circuitry, so you get the lens check warning as the camera does not think there is a lens attached. As Canons EOS lenses are electronically controlled, most Canon EF mount lenses do not feature a manual aperture ring, so when used on our EOS-M4/3, which is a full manual operation adapter ring, the aperture could not be transferred to the camera, it will stop down to its smallest f/stop by default. Infinity focus position: the position of the infinity mark ???of the telephoto lens or super telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity.
