The Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in their line of Mirrorless Interchangeable-Lens Cameras. It is currently only compatible with Fujinon XF and XC lenses and Carl Zeiss AG Touit, however there is an adaptor to allow compatibility with Leica M lenses[1] and third-party options have also been announced.[2] Additionally, a host of adapters for a range of SLR lenses are available, allowing the mounting of lenses (without autofocus or auto aperture) from Canon, Nikon, Minolta, Contax/Yashica, Konica and more.

"By mounting the lens deeper inside the camera, closer to the sensor, resolution is increased across the frame. Information exchange between the body and lens ensure a responsive experience at all times."[3]

Fujifilm X-Mount Cameras[edit]

As of January 2014, Fujifilm has released six cameras that use the X-mount.

  • Fujifilm X-Pro1: The first X-mount camera, the X-Pro 1 has a traditional rangefinder styled body with a 16 megapixel X-Trans sensor and a hybrid viewfinder that combines an optical viewfinder that utilizes frame lines like a rangefinder, and the ability to switch to an Electronic Viewfinder.
  • Fujifilm X-E1: Released in September 2012, the X-E1 is smaller than the X-Pro1, but features the same 16 megapixel sensor and almost all the features except the optical viewfinder. Instead, the X-E1 features a higher resolution electronic viewfinder.
  • Fujifilm X-M1: Released in July 2013, the X-M1 is the smallest X-mount camera, but shares the same 16 megapixel APS-C sensor as its larger brethren. It does not have an integrated viewfinder, nor standard shutter speed dial, but instead features a higher resolution tilting rear screen. The X-M1 also contains an upgraded image processor, allowing for faster image processing and improved responsiveness. Has Full HD stereo capability, RAW and equipped with Wi-Fi.[4]
  • Fujifilm X-A1: Released in September 2013 as an entry-level model X-mount camera, the X-A1 shares the body with the X-M1 but has a 16 megapixel sensor with a conventional Bayer color filter array instead of the X-Trans sensor.
  • Fujifilm X-E2: Released in October 2013, the X-E2 is an upgrade to the X-E1.
  • Fujifilm X-T1: Released in January 2014, the X-T1 has a weather-sealed body and tilting screen. It is also the first X-mount camera to offer an optional battery grip, and is the first camera from any manufacturer to fully support UHS-II SD cards.[5]

Fujinon XF and XC Lenses[edit]

The following lenses are natively operational on the Fujifilm X-mount cameras. These include Fujifilm's 'XF' and 'XC' lens line, bearing Fujifilm's moniker "Fujinon" which is used for optics within the company, and the 'Touit' line from Carl Zeiss AG. There are several Fujinon X-mount lenses available and three Zeiss Touit lenses available:

  • Fujinon XF 14mm f/2.8 R: This ultra-wide angle lens features a focus-clutch mechanism for switching to manual focus. The lens was announced in September, 2012.
  • Fujinon XF 18mm f/2.0 R: A wide-angle pancake style lens and one of the original three lenses for the X system.
  • Fujinon XF 23mm f/1.4 R: This is a fast moderate wide angle lens, equivalent to a 35mm lens in field of view on a full-frame camera.
  • Fujinon XF 27mm f/2.8: This is a wide standard lens with a very slim pancake design. This lens does not feature an aperture ring like most lenses in the Fujinon lineup. The lens was officially announced on June 24, 2013.

  • Fujinon XC 16-50mm f/3.5-5.6 OIS: This lens is a consumer-grade standard zoom, covering super wide to short telephoto, equivalent to 24-76mm on a full frame camera. The lens is the 'kit' lens for the X-M1 camera, and has a lower end build quality than the other Fujinon lenses, while maintaining good optical quality. This lens is the first lens in the new 'XC' line and does not have an aperture ring. This lens was officially announced on June 24, 2013.
  • Fujinon XF 55-200mm f/3.5-4.8 R LM OIS: A telephoto zoom lens with fast maximum aperture. This lens was officially announced on April 17, 2013.

  • Fujinon XF 56mm f/1.2 R: This is a standard portrait length lens, with a field of view similar to an 85mm lens on a full frame camera with a fast f/1.2 aperture. Officially announced on January 6, 2014.
  • Fujinon XF 18-135mm f/3.5–5.6 R LM OIS WR: A weather-resistant, image-stabilized superzoom, covering focal lengths equivalent to 27–202.5mm on full-frame. Officially announced on June 16, 2014.

The following lenses appear on Fujifilm's official lens roadmap for the X-series, and are expected for release by 2015.[7]

  • Fujinon XF 16-55mm f/2.8 R OIS WR: An enthusiast-level standard zoom, covering focal lengths equivalent to 24–82.5mm on full-frame, featuring weather-resistant construction and image stabilization. This lens is expected to be available in mid-2014.
  • Fujinon XF 50-140mm f/2.8 R OIS WR: A weather-resistant fast telephoto zoom with image stabilization, covering focal lengths equivalent to 75–210mm on full-frame. This lens is expected to be available in late 2014.

Short back focusing distance[edit]

By reducing the distance between the rear lens element and the sensor, light fall-off towards the edges of the frame is minimised, while resolution is maintained from edge to edge.

  • XF18mm / Back focus distance: 11.0mm
  • XF35mm / Back focus distance: 21.9mm
  • XF60mm / Back focus distance: 21.0mm
