Fujifilm X-mount

The Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in their X-series line of mirrorless interchangeable-lens cameras.

Various lens manufacturers use this mount, such as Fujinon (Fujifilm, XF and XC lenses), Carl Zeiss AG (Touit lenses), Samyang Optics, Handevision, SLR Magic, and Zhongyi Optics. There also is an adaptor to allow compatibility with Leica M lenses and third-party options have also been announced. 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."

History

20th century

Fuji Photo Film Co., Ltd. was established in 1934 with the aim of being the first Japanese producer of photographic films. Over the following 10 years, the company produced photographic films, motion-picture films and X-ray films. In the 1940s, Fuji Photo entered the optical glasses, lenses and equipment markets. After the Second World War, Fuji Photo diversified, penetrating the medical (X-ray diagnosis), printing, electronic imaging and magnetic materials fields. In 1962, Fuji Photo and U.K.-based Rank Xerox Limited (now Xerox Limited) launched Fuji Xerox Co., Ltd. through a joint venture.

Metadata

Metadata is "data that provides information about other data". Two types of metadata exist: structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.

Metadata was traditionally in the card catalogs of libraries. As information has become increasingly digital, metadata is also used to describe digital data using metadata standards specific to a particular discipline. Describing the contents and context of data or data files increases their usefulness. For example, a web page may include metadata specifying what language the page is written in, what tools were used to create it, and where to find more information about the subject; this metadata can automatically improve the reader's experience.

The main purpose of metadata is to facilitate in the discovery of relevant information, more often classified as resource discovery. Metadata also helps organize electronic resources, provide digital identification, and helps support archiving and preservation of the resource. Metadata assists in resource discovery by "allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information."
