The macro function of this adapter provides a focusing helicoid that will increase the lens-to-sensor distance, allowing for closer focusing than normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use. This macro helicoid can be used with any Canon EOS or Nikon F adapter to greatly expand the versatility.Compatible Nikon F Cameras (including but not limited to):D7100, D7000, D5300, D5200, D5100, D5000, D3300, D3200, D3100,D3000, D800, D800E, D700, D610, D600, D300, D300S, D200, D100, D50,D60, D70, D80, D90, D40, D40x, N70s, D4, D4S, D3, D3S, D3X, D2, D2H,D2Hs, D2X, D2Xs, D1, D1H, D1X, DFNote: This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop All pictures are for illustration purposes only.
