X Mount

Original “ X Mount” instantly communicates XF lens information to
the body, exploiting the full potential of FUJINON Lens optical performance.

To exploit every photon of the exceptional descriptive performance of these new lenses, an original lens mount has been specially designed for X-Pro1. The reinforcedmount ring is remarkably thin - approximately 2.5mm - further improving X-Pro1’s slim profile when the lens is mounted. Using a 10 pin system, the lens instantly sends information to the camera body through the lens mount, making the lenses work seamlessly with the body and letting the photographer concentrate on what is really important - beautiful photographic expression.

Shorter back focus – the defining difference of XF lens design.

Specifically designed to maximize the mirrorless design of the body, the X-Mount has a short flange back distance of just 17.7mm. This means the rear lens elements are as close as possible to the sensor. The wide opening allows the lens to be mounted deeper within the body – up to 7.5mm (approx) from the mount surface – reducing the back focus distance of each lens to the minimum possible, thus achieving high resolution all the way to the edge of the image.

World’s shortest*1 flange back distance of 17.7mm achieved by the X Mount design.
