Flange Distance
For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the interlocking metal rings on the camera and the rear of the lens) to the photographic film, film or image sensor plane. This value is different for different camera systems. The range of this distance, which will render an image clearly in focus (optics), focus within all focal lengths, is usually measured to a precision of hundredths of millimetres, and is not to be confused with depth of field. Lenses can be adapted from one lens mount, mount (and respective FFD) to another. FFD determines whether infinity focus can be accomplished with a simple non-optical adapter. Optics to correct for distance introduce more cost and can lower image quality, so non-optical lens adap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flange Focal Length (2 Types Camera)
A flange is a protruded ridge, lip or rim (wheel), rim, either external or internal, that serves to increase shear strength, strength (as the flange of a steel beam (structure), beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe (fluid conveyance), pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a railroad car, rail car or tram train wheel, wheel, which keep the wheels from derailment, running off the rail profile, rails). Flanges are often attached using bolts in the pattern of a bolt circle. Flanges play a pivotal role in piping systems by allowing easy access for maintenance, inspection, and modification. They provide a means to connect or disconnect Pipe (fluid conveyance), pipes and equipment without the need for welding, which simplifies installation and reduces downtime during ...

Hasselblad
Victor Hasselblad AB is a Sweden, Swedish manufacturer of medium format (film), medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans Moon landing, landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. In 2016, Hasselblad introduced the world's first digital compact mirrorless medium-format camera, the X1D-50c, changing the portability of medium-format photography. Hasselblad produces about 10,000 cameras a year from a small three-storey building. Company history The company was established in 1841 in Gothenburg, Sweden, by Fritz Wiktor Hasselblad, as a trading company, F. W. Hasselblad and Co.

Micro Four Thirds System
The is a standard released by Olympus Imaging Corporation and Panasonic in 2008, for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses. Camera bodies are available from Blackmagic, DJI, JVC, Kodak, Olympus, OM System, Panasonic, Sharp, Logitech Mevo and Xiaomi. MFT lenses are produced by Cosina Voigtländer, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sharp, Sigma, SLR Magic, Tamron, Tokina, TTArtisan, Veydra, Xiaomi, Laowa, Yongnuo, Zonlai, Lensbaby, Venus Optics and 7artisans amongst others. The specifications of the MFT system inherit the original sensor format of the Four Thirds system, designed for DSLRs. However, unlike Four Thirds, the MFT system design specification does not require lens telecentricity, a parameter which accommodated for the inaccurate sensitivity to off-angle light due to the geometry of the photodetectors of contemporary image sensors. Later improvements in manufacturing capa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sony FZ-mount
CineAlta cameras are a series of professional digital movie cameras produced by Sony that replicate many of the same features of 35mm film motion picture cameras. Concept CineAlta is a brand name used by Sony to describe various products involved in content creation, production and exhibition process within digital cinema workflow.The first Cinealta camera is Sony HDW-900, and the first camera HD 24p. Now Sony's products branded as CineAlta include camera, camcorder, recorder, cinema server, and projector. "CineAlta" is a portmanteau of Cine, from cinematography, and Alta, an Italian word for "high". Logo The first CineAlta logo was designed by Hiroki Oka, Chief Art Director of Sony CreativeWorks Corporation, based at the Sony Atsugi Technology Center. The twinned ribbons represent the marriage of film and videotape, arranged in a way to deliberately evoke the infinity symbol, to symbolize the infinite possibilities. The CineAlta logo was updated by Tetsuro Sano and appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sony E-mount
The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience") and Sony ILCE camera, ILCE series of camcorders and mirrorless interchangeable lens camera, mirrorless cameras. The E-mount supplements Sony's Sony α, α mount, allowing the company to develop more compact imaging devices while maintaining vignetting with 35mm sensors. E-mount achieves this by: * Minimising mechanical complexity, removing mechanical aperture and Focus (optics), focus drive. * Shortening the flange focal distance to 18 mm compared with earlier offerings from Sony which used 44.5 mm. * Reducing the radius of the flange. * Relying on software to correct vignetting The short flange focal distance prohibits the use of an optical viewfinder, as a mirror box mechanism cannot be included in this reduced distance. Therefore, all E-mount cameras use an electronic viewfinder. History Initially, E-mount was implemented on the Sony α Sony NEX-3, NEX-3 and Sony NEX-5, NEX-5 consume ...

List Of Canon EF-M Lenses
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Canon EF-M Mount
The Canon EF-M lens mount, introduced in 2012, was a derivative of the Canon EF lens mount designed for use with the Canon EOS M mirrorless interchangeable-lens camera. The EF-M lens mount is one of Canon's two systems for mirrorless cameras, the other being the RF mount. The M system has an 18 mm flange focal distance (compared to 20 mm for RF and 44 mm for EF and EF-S) and a 47 mm throat diameter (compared to 54 mm for EF, EF-S, and RF). As it is designed for use with an APS-C-sized image sensor, it features the same crop factor In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital ... (of roughly 1.6) as the existing EF-S lens mount. The M system was somewhat limited as Canon had only released 8 native lenses, listed below. There was a lack of native lenses ...

Fujifilm X-mount
The Fujifilm X-mount is a lens mount for Fujifilm interchangeable lens mirrorless cameras in its X-series, 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.
