The Fujifilm G-mount is a type of interchangeable lens mount designed by Fujifilm for use in the cameras of their Fujifilm GFX series. These cameras have interchangeable lenses. The respective lenses are designed for 43.8 mm x 32.9 mm medium format sensors. Fujifilm G-mount cameras Fujifilm has released the following cameras that use the G-mount: *Fujifilm GFX 50S * Fujifilm GFX 50R * Fujifilm GFX100 * Fujifilm GFX100S * Fujifilm GFX50S II Fujifilm G-mount lens system The crop factor compared to the 35 mm format as a reference is 0.79. Ratio of the reference frame's diagonal (35 mm format) to the diagonal of the image sensor in question (Fujifilm GFX): \dfrac\approx0.790 As of November 2022 there are 27 lenses available for the G-mount; 14 from Fujifilm's Fujinon brand and 13 from third party companies.

MILC
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount. Terminology Mirrorless cameras are sometimes referred to as mirrorless interchangeable-lens cameras (MILC), or digital single-lens mirrorless (DSLM) cameras. This latter name highlights their connection to DSLRs. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs). Overview Mirrorless cameras are mechanically simpler than Digital single-lens reflex camera, DSLR cameras, and are smaller, lighter, and quieter due to the elimination of the moving mirror. While nearly all mirrorless cameras have a mechanical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujinon
Fujinon is a brand of optical lenses made by Fuji Photo Film Co., Ltd, now known as Fujifilm. Fujifilm's Fujinon lenses have been used by professional photographers and broadcast stations as well as cinematography. Fujifilm started manufacture of optical glass in its Odawara Factory in Japan in 1940, which was the start of the Fujinon brand. They were proud of their use of expensive Platinum crucibles to get the purest glass achievable at the time. Fujifilm also pioneered Electron Beam Coating (EBC) which according to Fujifilm, represented a new high in lens precision and performance. The EBC process was significantly different from other coating processes by the number of coating, the thinness of the coating, and the materials used for coating. Fujifilm claimed they were able to have as much as 14 layers of coating and used materials such as zirconium oxide, and cerium fluoride, which could not be used for coating in the conventional coating process. The first lens to offer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujifilm X Series
The Fujifilm X series is a line of digital cameras produced by Fujifilm. The series encompasses fixed lens and interchangeable lens mirrorless cameras and premium compact point-and-shoot cameras aimed at consumer, enthusiast and professional photographers. The X series is part of the larger FinePix range of digital cameras from Fujifilm. The X series models use either APS-C or inch sensors. X series model lines Since its introduction with the X100 in 2011, the X series has grown to encompass a wide variety of designs. These lines can be broken out into the following categories or model lines. APS-C sensor The following lines are united by their use of APS-C-sized sensors measuring 25.1×16.7 mm, with an aspect ratio of 3:2 and Ø31.15 mm field diameter. They are listed here within each category in the order in which the initial model of each type was introduced. Fixed lens * X100 line — These models have a fixed focal length 23mm prime lens and a hybrid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujifilm X-mount
The Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in those cameras in their X-series line that have interchangeable-lenses. These lenses are designed for 23.6mm x 15.6mm APS-C sensors. Various lens manufacturers use this mount, such as Fujifilm's own XF and XC lenses, Carl Zeiss AG (Touit lenses), Samyang Optics, Handevision, SLR Magic, Viltrox and Zhongyi Optics. 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, Pentax, Minolta, Contax/Yashica, Konica and more. This mount type should not be confused with the discontinued Fujica X-mount, which is not compatible with the newer X-mount without an adapter. Fujifilm X-Mount cameras Fujifilm has released the following cameras that use the X-mount: *Fujifilm X-A1 *Fujifilm X-A2 *Fujifilm X-A3 *Fujifilm X-A5 *Fujifilm X-A7 *Fujifilm X-A10 *Fujifilm X-A20 *Fujifilm X-E1 *Fujifilm X ...

Teleconverter
A teleconverter (sometimes called tele extender) is a secondary lens mounted between a camera and a photographic lens which enlarges the central part of an image obtained by the lens. For example, a 2× teleconverter for a 35 mm camera enlarges the central 12×18 mm part of an image to the size of 24×36 mm in the standard 35 mm film format. Teleconverters are typically made in 1.4×, 1.7×, 2× and 3× variants, with 1.4× and 2× being the most common. A 2× teleconverter doubles the apparent focal length of a given lens. Teleconverters also decrease the intensity of the light that reaches the film plane (or sensor) by the square of its magnification. A 2× teleconverter reduces the light to 1/4, doubles the focal ratio and halves the resolution of the master lens it is connected to. This, however, does not necessarily halve the resolution of the digital image. A closely related device reduces the focal length. It is generally marketed under the name speed ...

ISO8601
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times. ISO 8601 applies to these representations and formats: ''dates,'' in the Gregorian calendar (including the proleptic Gregorian calendar); ''times,'' based on the 24-hour timekeeping system, with optional UTC offset; ''time intervals''; and combinations thereof.ISO 8601:2004 section 1 Scope The standard does not assign specific meaning to any element of the dates/times re ...
