Leica S-System
The Leica S-System is a medium format digital single lens reflex camera system introduced by Leica Camera in 1996. Beginning with the Leica S1, a prototype top-end studio digital camera unveiled at Photokina 1996. It went into production at the end of 1997. Leica S-System cameras * Leica S1 – The Leica S1 Pro is a scanner camera with a very high resolution (26.4 megapixels) for stationary use introduced in 1996. On a 36×36 mm2 sensor 5140×5140 pixels are scanned and optically transferred to a connected computer. The object lens adapter system was exchangeable, thus object lenses of the systems Leica R, Leica M, Hasselblad, Mamiya 4, 5×6, and all mechanical objective lenses from Canon (FD), Nikon, etc. can be used with the S1. The software for the S1 is a special SilverFast version, originally developed by LaserSoft Imaging for high-end scanners. Approximately 160 cameras were built and mostly sold to museums, archives and research institutes. Later on Leica introduced the ...

Medium Format
Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the used in 35 mm photography (though not including 127 sizes), but smaller than (which is considered large format photography). In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range. Characteristics Medium-format cameras made since the 1950s are generally less automated than smaller cameras made at the same time. For example, autofocus became available in consumer 35 mm cameras in 1977, but did not reach medium format until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Processor
An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for image processing, in digital cameras or other devices. Image processors often employ parallel computing even with SIMD or MIMD technologies to increase speed and efficiency. The digital image processing engine can perform a range of tasks. To increase the system integration on embedded devices, often it is a system on a chip with multi-core processor architecture. Function Bayer transformation The photodiodes employed in an image sensor are color-blind by nature: they can only record shades of grey. To get color into the picture, they are covered with different color filters: red, green and blue (RGB) according to the pattern designated by the Bayer filter - named after its inventor. As each photodiode records the color information for exactly one pixel of the image, withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leica S-mount Cameras
Leica Camera AG () is a German company that manufactures cameras, optical lenses, photographic lenses, binoculars, rifle scopes and microscopes. The company was founded by Ernst Leitz in 1869 (Ernst Leitz Wetzlar), in Wetzlar, Germany. In 1986, the Leitz company changed its name to Leica, due to the fame of the Leica trade-name. The name Leica is derived from the first three letters of the founder's surname (Leitz) and the first two of the word camera: lei-ca (LEItz CAmera). At this time, Leica relocated its factory from Wetzlar to the nearby town of Solms. Leica Camera AG is 55% owned by Austrian investment firm ACM Projektentwicklung GmbH, and 45% owned by The Blackstone Group which licenses the Leica brand name from the Danaher Corporation-owned Leica Microsystems GmbH. History From the year 1907 to the 1950s, the buildings that formed Leica factory were built on Ernst Leitz Street in Wetzlar, and remained until 1986, when the factory was moved to the city of Solms.

Leica L-Mount
The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras. The L-Mount has an inner diameter of 51.6 mm and a flange depth of 20.0 mm. The L-mount exists in two versions, an APS-C version (TL) and a full-frame version (SL). The two versions are mechanically and electronically compatible. TL lenses mounted on full-frame cameras will cause the camera to use a crop mode from the center of the sensor, corresponding to the APS-C coverage of the lens. SL lenses mounted on TL cameras function normally, providing a 1.5x crop field of view, as is typical with APS-C cameras. In 2018 Leica formed the L-Mount Alliance, licensing Sigma, Panasonic in the same year, and DJI in 2022, to use an upgraded version of the mount for their own products, opening the way for a more extensive system of fully compatible cameras and lenses. T-Mount to L-Mount It was introduced in April 2014 with the Leica T (Typ 701) camera. At the time of introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summicron
The name Summicron is used by Leica to designate camera lenses that have a maximum aperture of f/2 after 1953 and to present day. History The name Summicron is derived from ''summus'', latin word for maximum and ''kronos'', the ancient Greek word for time. In the 1950s Leica bought Crown glass from Chance Brothers, an English company and used it to make the lenses. Leica designed a number of f/2 lenses before the Summicron, such as the Summar and Summitar. New coating technologies available after World War II allowed for the creation of the Summicron lens. The first Summicron was an evolved Summitar collapsible 50mm with Lanthanum glass, and was launched in 1953. Generations before approximately 1960 were produced in M39 mount ("screw mount"), then made available in M-mount (Latch-on A42), R-mount, and C-mount. Description The Summicron lenses have a maximum f-number of f/2. Market position Faster Leica lenses are offered with the trade names Noctilux (or Nocticron) and Su ...

Summarit
The name Summarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.4. The name has been in used since 1949. History The Summarit was initially introduced as Leica's fastest lens in 1949 with a maximum aperture of f/1.5. Since then, the Noctilux and Summilux named lenses have superseded this old aperture. On 3 August 2007 Leica revived the name and announced a series of less expensive lenses, the Summarit-M. The Summarit-M lenses work on Leica M-series film and digital rangefinder cameras. Description In its current iteration the Summarit lenses have a maximum f-number of f/2.4. Market positions Leica introduced these less expensive lenses, which also fit Leica M mount cameras like the recent Cosina (Carl Zeiss AG and Voigtländer brands) lenses as an alternative to its main line professional and expensive lenses.

Elmarit
The name Elmarit is used by Leica to designate camera lenses that have a maximum aperture of f/2.8. History The Elmarit is a derivation of the Elmar. Confusingly not all f/2.8 lenses are Elmarits. The 50 mm f/2.8 collapsible, manufactured until 2007, was designated an Elmar rather than an Elmarit. Description The Elmarit are popular lenses for extreme focal lengths: 21 mm, 24 mm, 28 mm and 90 mm. The Elmarit has also come in 135mm super-telephoto. Market positions The Elmarit are behind the Summicron and the Summarit lenses. Only the Elmar and most Summaron lenses have a smaller f-number. List of Elmarit lenses ;For the Leica M mount The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M-series cameras and certain accessories (e.g. Visoflex reflex viewing attachment) up to the current film L ...: * Elmarit-M 21 mm * Elmarit-M 21 mm ASPH. * Elmarit-M ...

Elmar (lens)
The name Elmar is used by Leica to designate camera lenses of four elements that have a maximum aperture of f/3.98 or f/4.0. History The Elmar lenses originally had a maximum aperture of f/3.5. These lenses were derived from a 50 mm f/3.5 Elmax lens first produced in 1925. The name is a combination of Ernst Leitz and Max Berek. Description Elmar lenses variously has a maximum f-number of f/2.8 or f/3.4 or f/3.8 or f/4. Currently the Elmar lenses have a maximum aperture of f/3.8 or f/4, as in the Elmar-M 24 mm f/3.8 and Tri-Elmar-M 16-18-21 mm f/4. The name Elmar is sometimes combined with: Super, Tele, APO, Macro or Vario. Market positions Elmar lenses are comparatively slow. As a result they tend to be smaller and lighter than faster lenses of the same focal length.

4K Video
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K UHD) is the dominant 4K standard, whereas the movie projection industry uses 40962160 ( DCI 4K). The 4K television market share increased as prices fell dramatically during 2014 and 2015. 4K standards and terminology The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p". While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 pixels equal approximately 8.3 megapixels, which is not considered to be es ...

Active Pixel Sensor
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the image sensor is sometimes c ...

Leica S (Typ 007)
The Leica S2 is a digital medium format DSLR camera announced by Leica Camera on September 23, 2008. It features a Kodak-made custom CCD sensor measuring 30×45 mm and containing 37 million pixels. This sensor has a 26% longer diagonal and 56% larger area than a "full-frame″ 24×36 mm DSLR sensor and outputs an approximately 5000x7500 pixel image. The S2 is thus a medium format camera in a " 35 mm SLR"-sized body. The new "Maestro" image processor used in the S2 was developed by Fujitsu based on the Milbeaut and the autofocus system (Leica's first to see production) was developed in house. The design of the body is by Manfred Meinzer, who made the design of the analogous Leica R8 The Leica R8 & R9 are manual focus 35 mm single-lens reflex cameras produced by the German firm Leica as the final models of their R series. Development of the R8 began in 1990: the camera was introduced at the 1996 photokina trade show, a ..., too. The S2 series body, lenses and ...
