Feature 3Original X Mount

Designed for maximum performance of the lens, the "X mount" promises excellent image quality. The FUJINON XF lens information is communicated instantly once connected to the original Fujifilm X Mount.

Taking full advantage of the mirrorless design, the mount boasts a short 17.7mm flange back distance, a wider opening and deeper mounting of the lens, resulting in reduction of back focus distance to the minimum possible while achieving high resolution extending to the image edge areas. When a FUJINON XF lens is mounted, all lens information is instantly communicated to the body, integrating them into a seamless, responsive instrument.
