Fotodiox M42-M42-Macro M42 Focusing Helicoid for Carl Zeiss

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 M42 adapter on either end: allowing you to use M39 M42 Nikon Leica and more lenses on any M42 camera body or a M42/M39 (with adapter) lens on Nikon Canon Sony Olympus and more camera bodies. This helicoid tube is also very useful for lenses without a focus ring such as enlarger lenses.
