In photography, bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting . Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions.
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 the Electron Beam Coating was the EBC Fujinon 55mm F3.5 Macro in 1972. Light transmission for the coating was said to be 99.8%. EBC later evolved into Super-EBC and HT-EBC.
The Bell D-188A was a proposed eight-engine Mach 2–capable vertical take-off and landing (VTOL) tiltjet fighter that never proceeded past the mock-up stage.
Originally produced by Minolta, and currently produced by Sony, the STF 135mm f/2.8 [T4.5] is a photographic lens compatible with cameras using the Minolta AF and Sony α A-mount. STF stands for Smooth Trans Focus, in reference to its special optical system, which is intended to smooth the transition between the plane of focus and out-of-focus areas in the image. This is accomplished by the use of an apodization filter that provides the high-quality bokeh effect. The lens is not a soft-focus lens.
The Fujifilm X series of digital cameras consists of Fujifilm's high-end digital cameras and is aimed at professional and keen enthusiast photographers. It is part of the larger range of Fujifilm's digital cameras. The X series itself is not characterized by a single common sensor size or technology.
The Fujifilm X-Pro1 is a mirrorless interchangeable-lens digital camera announced in January 2012 and launched in March 2012. It is part of Fujifilm's X-Series of cameras. In October 2012 Fujifilm has released a very similar, yet smaller, camera named the X-E1. In January 2016 Fujifilm announced its successor the X-Pro2.
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.
The Fujifilm X100 is a series of digital compact cameras with a fixed prime lens. The series includes the FinePix X100,X100S,X100T and X100F. They each have a large image sensor and a 23 mm lens. All four cameras have received generally positive reviews.
The Smooth Trans Focus (STF) technology in photographic lenses uses an apodization filter to realize notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. This is accomplished by utilizing a concave neutral-gray tinted lens element next to the aperture blades as apodization filter, a technology originally invented by Minolta in the 1980s, and first implemented in a commercially available lens in 1999. In contrast to soft focus lenses, STF lenses render a perfectly sharp image in the focus plane.
The Fujifilm X-T1 is a DSLR-style weather-resistant mirrorless camera announced by Fujifilm on January 28, 2014. It uses the Fujifilm X-mount.
The Fujifilm X10 is a large sensor digital compact camera announced by Fujifilm on September 1, 2011. At the time of its release, it competed most closely with the Panasonic Lumix DMC-LX5, Olympus XZ-1, Canon PowerShot G1 X and Sony Cyber-shot DSC-RX100, and was subsequently named a 2013 iF product design award recipient.
The Fujifilm X-T10 is a DSLR-styled mirrorless camera announced by Fujifilm on May 18, 2015. In January 2017 Fujifilm announced its successor the X-T20.
The Fujinon XF 16mm F1.4 R WR is an interchangeable camera lens announced by Fujifilm on April 16, 2015. It has an unusually wide maximum aperture given its focal length, and is weather-sealed.
The Fujinon XF 56mm F1.2 R is an interchangeable camera lens announced by Fujifilm on January 6, 2014. As of 2015, it is one of the widest-aperture native mirrorless lenses.
The Fujifilm XF 35mm F1.4 R is an interchangeable camera lens announced by Fujifilm on January 9, 2012. As of 2015, it remains one of the widest-aperture 35mm lenses available, giving a normal field of view on Fujifilm's APS-C format digital cameras.
The Fujinon XF 60mm F2.4 R Macro is an interchangeable camera lens announced by Fujifilm on January 9, 2012. It is not a true macro lens, with magnification up to 1:2 rather than 1:1. As of July 2015, it is the only lens marketed for close-up work among Fujifilm's X mount offerings. However, Zeiss offers the Touit Makro-Planar T* 50mm f/2.8, which offers 1:1 magnification.
The Fujinon XF 27mm F2.8 is an interchangeable camera pancake lens announced by Fujifilm on June 25, 2013. At 27 mm, it has a 35 mm equivalent focal length of 41 mm, making it a normal lens of maximum aperture f/2.8. The intended benefit of this lens is its extreme compact size, extending only 23 mm (0.91 in) from the flange, and light weight, only 77.3 g (2.73 oz), with the trade off of having no aperture ring.
The Fujinon XF 35mm F2 R WR is an interchangeable standard prime lens for X-mount, announced by Fujifilm on October 21, 2015.
The Fujinon XF 90mm F2 R LM WR is an interchangeable camera lens announced by Fujifilm on May 18, 2015.
The Fujifilm GFX 50S is a mirrorless medium format camera produced by Fujifilm. It was announced by Fujifilm during the photokina 2016 exhibition in Cologne, Germany, and production began at the start of 2017.The camera was available for sale from February 28, 2017.
