The MCEX-16 16mm Extension Tube from Fujifilm is is a dedicated extension tube that is designed exclusively for XF and XC lenses and X-series cameras. Mounting an extension tube between a lens and a camera body increases the distance between the lens elements and the sensor enabling users to focus closer than the normal minimum focus distance of the lens.
This 16mm 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.
