This 11mm extension tube features electronic contacts that pass information between Fujinon X-Mount lenses and Fujifilm X-series camera bodies and retains autofocus and auto exposure capability. When am extension tube is attached, the focus range of the lens is limited so users can also find a focus point by moving the camera forward and backward.

The mount rings of the tube are made of solid metal and designed to precisely fit the X-series lenses and cameras, also the look and feel of the tube seamlessly blends with the X-Series line of compact system cameras. The below table details the minimum working distance and minimum focus distance of compatible X-mount lenses with and without the extension tube attached.
