Fotodiox Vzlx-NikG-EOS-Macro Vizelex Macro Focusing Helicoid for Nikon F D SLR Lens

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.
