76-478: The Pentax K-7 is a 14.6-megapixel digital single-lens reflex camera , announced on 20 May 2009. This is the first new flagship model released by Pentax since its merger with Hoya Corporation on 31 March 2008. It was discontinued late in 2010 in favour of the K-5 . The Pentax K-7 was announced on 20 May 2009 and shipping began as of the first week of July 2009. The K-7 has the same pixel count as its predecessor,

152-420: A pentamirror instead of the traditional pentaprism . Focusing can be manual, by twisting the focus on the lens; or automatic , activated by pressing half-way on the shutter release or a dedicated auto-focus (AF) button. To take an image, the mirror swings upwards in the direction of the arrow, the focal-plane shutter opens, and the image is projected and captured on the image sensor . After these actions,

228-568: A " digital back " which can be used as an alternative to a film back. Because of the manufacturing costs of these large sensors, the price of these cameras is typically over $ 1,500 and easily reaching $ 8,000 and beyond as of February 2021 . " Full-frame " is the same size as 35 mm film (135 film, image format 24×36 mm); these sensors are used in DSLRs such as the Canon EOS-1D X Mark II , 5DS/5DSR , 5D Mark IV and 6D Mark II , and

304-434: A "PASM" dial, they typically provide modes such as program, aperture-priority, shutter-priority, and full manual modes. Scene modes vary from camera to camera, and these modes are inherently less customizable. They often include landscape, portrait, action, macro, night, and silhouette, among others. However, these different settings and shooting styles that "scene" mode provides can be achieved by calibrating certain settings on

380-419: A color-striped 2/3” format CCD sensor with 280K pixels, along with analog video signal processing and recording. The Mavica electronic still camera employed a TTL single-lens reflex viewfinder, as shown in the graphic from a June 1982 Sony press release. It recorded FM-modulated analog video signals on a newly developed 2” magnetic floppy disk, dubbed the "Mavipak". The disk format was later standardized as

456-623: A developer of nanoprint lithography systems, for an amount speculated to be around US$ 98 million. On 13 June 2014, Canon announced it had acquired Danish IP Surveillance VMS software company Milestone Systems. Milestone provides open-platform software to allow video management from various vendors in a single interface; therefore the company will operate as a separate entity. On 10 February 2015, Canon announced that it had intentions to buy Swedish Security Camera maker Axis Communications for US$ 2.83 billion. On 23 February 2015, Axis Communications reacted to this news and confirmed that it had received

532-533: A distant third at 6.3%. In 2008, Canon 's and Nikon 's offerings took the majority of sales. In 2010, Canon controlled 44.5% of the DSLR market, followed by Nikon with 29.8% and Sony with 11.9%. For Canon and Nikon, digital SLRs are their biggest source of profit. For Canon, their DSLRs brought in four times the profits from compact digital cameras, while Nikon earned more from DSLRs and lenses than from any other product. Olympus and Panasonic have since exited

608-659: A field zoom lens for television broadcasting in 1958, and in 1959 introduced the Reflex Zoom 8 and the Canonflex . In 1961, Canon introduced the Rangefinder camera, Canon 7 , and 50mm 1:0.95 lens in a special bayonet mount. In 1964 Canon introduced the 'Canola 130', the first Japanese made 10-key calculator , a substantial improvement on the design of the British Bell Punch company, which introduced

684-690: A focal-plane-based shutter. In 1947, the company name was changed to Canon Camera Co., Inc. , shortened to Canon Inc. in 1969. The name Canon comes from Buddhist bodhisattva Kannon ( Japanese : 観音 , lit.   ' Guanyin '), previously transliterated as Kuanyin, Kwannon, or Kwanon in English. The origins of Canon date back to the founding of Precision Optical Instruments Laboratory in Japan in 1933 by Takeshi Mitarai , Goro Yoshida  [ jp ] , Saburo Uchida  [ jp ] and Takeo Maeda  [ jp ] . It became

760-473: A larger variety of dedicated lenses and other equipment. Mainstream DSLRs (in full-frame or smaller image sensor format ) are produced by Canon , Nikon , Pentax , and Sigma . Pentax , Phase One , Hasselblad , and Mamiya Leaf produce expensive, high-end medium-format DSLRs, including some with removable sensor backs. Contax , Fujifilm , Kodak , Panasonic , Olympus, Samsung previously produced DSLRs, but now either offer non-DSLR systems or have left

836-624: A low-noise analog image signal, which is digitized when used in a digital camera. For their contribution to digital photography, Boyle and Smith were awarded the Nobel Prize for Physics in 2009. In 1973, Fairchild developed a 100 x 100 pixel interline CCD image sensor. This CCD was used in the first commercial CCD camera, the Fairchild MV-100 , which was introduced in late 1973. In 1974, Kodak scientists Peter Dillon and Albert Brault used this Fairchild CCD 202 image sensor to create

912-505: A nonstandard video resolution or frame rate. For example, the Pentax K-7 uses a nonstandard resolution of 1536×1024, which matches the imager's 3:2 aspect ratio. The Canon EOS 500D (Rebel T1i) uses a nonstandard frame rate of 20 frame/s at 1080p, along with a more conventional 720p30 format. In general, HDSLRs use the full imager area to capture HD video, though not all pixels (causing video artifacts to some degree). Compared with

988-680: A primary listing on the Tokyo Stock Exchange and is a constituent of the TOPIX Core 30 and Nikkei 225 indexes. It used to have a secondary listing on the New York Stock Exchange . The company was originally named Seikikōgaku kenkyūsho ( Japanese : 精機光学研究所 , lit.   'Precision Optical Laboratory'). In 1934, it produced the Kwanon , a prototype for Japan's first-ever 35 mm camera with

1064-687: A purchase proposal from Canon. The purchase was effectively completed in April 2015. On 24 April 2015, Canon Europe announced it had acquired the London-based family photo sharing startup Lifecake. In November 2015, in an effort to avoid the selling of gray-market camera gear, Canon USA filed litigation against a number of camera gear retailers. Retailers include Get It Digital, All New Shop and F&E Trading. In March 2016, Canon acquired Toshiba Medical Systems Corporation for US$ 5.9 billion. On 28 March 2017, Canon Europe announced it had acquired

1140-490: A range of wireless presenters, from advanced green laser presenters with back-lit screen display to basic red laser presentation clickers. Canon is developing a prototype virtual reality headset (Canon VR). The headset offers a wider viewing angle (120°) than other VR devices but requires handles rather than a head strap. The headset is not yet available on the market. As of 2020, Canon produces and sells high-end AR ( augmented reality ) headsets for enterprise users. Canon

1216-465: A separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILCs) beginning in the 2010s. In 1969, Willard S. Boyle and George E. Smith invented charge-coupled semiconductor devices, which can be used as analog storage registers and image sensors. A CCD (Charge-Coupled Device) imager provides

1292-525: A tethered hard drive and processed for histogram feedback to the user. This camera was created for the U.S. government, and was followed by several other models intended for government use and eventually Kodak DCS , a commercial DSLR series launched in 1991. In 1995, Nikon co-developed the Nikon E series with Fujifilm. The E series included the Nikon E2 / E2S , Nikon E2N / E2NS and Nikon E3 / E3S , with

1368-470: A variety of different lens mounts. There are also lens adapters that allow a lens for one lens mount to be used on a camera body with a different lens mount, but with often reduced functionality. Many lenses are mountable, "diaphragm-and-meter-compatible", on modern DSLRs, and on older film SLRs that use the same lens mount. However, when lenses designed for 35  mm film or equivalently sized digital image sensors are used on DSLRs with smaller sized sensors,

1444-619: A wide range of flatbed scanners , film scanners and document scanners for home and business use, including the Canon CanoScan 8800F . Some of its scanners employ LED inDirect Exposure (LiDE) technology, such that USB port is sufficient to power the scanner, and no additional power is required. Current printers use the proprietary BJNP protocol (USB over IP port 8611). Canon produced a range of calculators in various applications, including handheld calculators, desktop calculators, printing calculators and scientific calculators. One model

1520-521: Is a good example of this. When comparing two sensors of the same size, for example, two APS-C sensors one 12.1 MP and one 18 MP, the one with the lower megapixel rating will usually perform better in low light. This is because the size of the individual pixels is larger, and more light is landing on each pixel, compared with the sensor with more megapixels. This is not always the case, because newer cameras that have higher megapixels also have better noise reduction software, and higher ISO settings to make up for

1596-649: Is limited in its ability to find focus quickly, though it is somewhat more accurate. In 2012, Canon introduced hybrid autofocus technology to the DSLR in the EOS 650D/Rebel T4i , and introduced a more sophisticated version, which it calls "Dual Pixel CMOS AF", with the EOS 70D . The technology allows certain pixels to act as both contrast-detection and phase-detection pixels, thereby greatly improving autofocus speed in live view (although it remains slower than pure phase detection). While several mirrorless cameras , plus Sony's fixed-mirror SLTs , have similar hybrid AF systems, Canon

1672-524: Is not unique to the DSLR design and mirrorless interchangeable lens cameras are becoming increasingly popular. Interchangeable lenses for SLRs and DSLRs are built to operate correctly with a specific lens mount that is generally unique to each brand. A photographer will often use lenses made by the same manufacturer as the camera body (for example, Canon EF lenses on a Canon body) although there are also many independent lens manufacturers, such as Sigma , Tamron , Tokina , and Vivitar , that make lenses for

1748-495: Is one of the world's top producers of semiconductor and display manufacturing equipment. Its subsidiary Canon Tokki dominates the market of material deposition equipment, and instruments for manufacturing OLED displays. Canon is also the leading manufacturer of display photolithography equipment and one of the top 3 in the semiconductor lithography machine market. Once a leader of semiconductor lithography along with Nikon , it has been dwarfed by ASML , and as of 2017 its share in

1824-557: Is the only manufacturer that offers such technology in DSLRs. A new feature via a separate software package introduced from Breeze Systems in October 2007, features live view from a distance. The software package is named "DSLR Remote Pro v1.5" and enables support for the Canon EOS 40D and 1D Mark III . Image sensors used in DSLRs come in a range of sizes. The very largest are the ones used in " medium format " cameras, typically via

1900-537: Is useful in situations where the camera's eye-level viewfinder cannot be used, such as underwater photography where the camera is enclosed in a plastic waterproof case. In 2000, Olympus introduced the Olympus E-10 , the first DSLR with live preview – albeit with an atypical fixed lens design. In late 2008 , some DSLRs from Canon , Nikon , Olympus , Panasonic , Leica , Pentax , Samsung and Sony all provided continuous live preview as an option. Additionally,

1976-465: The K20D , but offers a significantly expanded feature set in a smaller body. New features include: VIDEO: 720p / 1080p / 4K This photography-related article is a stub . You can help Misplaced Pages by expanding it . Digital single-lens reflex camera The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through

2052-669: The Konica Minolta Maxxum 7D , the first DSLR with in-body image stabilization which later become standard in Pentax , Olympus , and Sony Alpha cameras. In early 2008, Nikon released the D90 , the first DSLR to feature video recording. Since then, all major companies have offered cameras with this functionality. Over time, the number of megapixels in imaging sensors has increased steadily, with most companies focusing on high ISO performance, speed of focus, higher frame rates,

2128-648: The Nikon D5 , D850 , D750 , D610 and Df . Most lower-cost DSLRs use a smaller sensor that is APS-C sized, which is approximately 24×16 mm, slightly smaller than the size of an APS-C film frame, or about 40% of the area of a full-frame sensor. Other sensor sizes found in DSLRs include the Four Thirds System sensor at 26% of full frame, APS-H sensors (used, for example, in the Canon EOS-1D Mark III ) at around 61% of full frame, and

2204-402: The digital image , performing data storage , and/or driving an electronic display . DSLRs typically use autofocus based on phase detection. This method allows the optimal lens position to be calculated rather than "found", as would be the case with autofocus based on contrast maximization. Phase-detection autofocus is typically faster than other passive techniques. As the phase sensor requires

2280-525: The "Still Video Floppy", or "SVF", so the Sony Mavica was the first "SVF-SLR" to be demonstrated, but it was not a D-SLR since it recorded analog video images rather than digital images. Starting in 1983, many Japanese companies demonstrated prototype SVF cameras, including Toshiba, Canon, Copal, Hitachi, Panasonic, Sanyo, and Mitsubishi. The Canon RC-701, introduced in May 1986, was the first SVF camera (and

2356-592: The 270EX II, 320EX, 430EX II, 430EX III-RT, 470EX-AI, 580EX, 580EX II, 600EX-RT, 600EXII-RT, EL-1, and EL-5 Speedlites. Canon also produces macro flash units, including the Macro Twin Lite and the Macro Ring Lite. Canon designs and manufactures CMOS image sensors in-house for its imaging products and it has three dedicated fabs in Japan . In 2016, Canon, the fifth-largest image sensor manufacturer in

2432-702: The Canon LBP-SX engine. Later models used the Canon LBP-LX, LBP-EX, LBP-PX engines and many other Canon print engines. Following Canon's acquisition of the Dutch digital printing manufacturer Océ in 2010, Canon continued to develop and manufacture printing systems, initially under the Océ brand name. On 1.1.2020 the company Océ was officially renamed Canon Production Printing . Canon has been sued over intentionally designing all-in-one printers that cannot scan when

2508-407: The DSLR market and now focus on producing mirrorless cameras. In 2013, after a decade of double-digit growth, DSLR (along with MILC ) sales were down 15 percent. This may be due to some low-end DSLR users choosing to use a smartphone instead. The market intelligence firm IDC predicted that Nikon would be out of business by 2018 if the trend continued, although this did not come to pass. Regardless,

2584-504: The DSLR's optical construction, HDSLRs typically lack one or more video functions found on standard dedicated camcorders, such as autofocus while shooting, powered zoom, and an electronic viewfinder/preview. These and other handling limitations prevent the HDSLR from being operated as a simple point-and-shoot camcorder, instead of demanding some level of planning and skill for location shooting. Video functionality has continued to improve since

2660-643: The E3S released in December 1999. In the late 1990s, Sony introduced the "Digital Mavica" series of consumer digital cameras. Unlike the original analog Mavica, the Digital Mavica cameras recorded JPEG compressed image files on standard 3½-inch magnetic floppy discettes (meant to simplify camera-to-computer data transfer) and did not have an SLR viewfinder. In 1999, Nikon announced the Nikon D1 . The D1's body

2736-488: The Fujifilm FinePix S5 Pro offers 30 seconds of live preview. On almost all DSLRs that offer live preview via the primary sensor, the phase-detection autofocus system does not work in the live preview mode, and the DSLR switches to a slower contrast system commonly found in point-and-shoot cameras . While even phase detection autofocus requires contrast in the scene, strict contrast-detection autofocus

2812-603: The Kodak Microelectronics Technology Division developed a 1.3 MP CCD image sensor, the first with more than 1 million pixels. In 1987, this sensor was integrated with a Canon F-1 film SLR body at the Kodak Federal Systems Division to create an early DSLR camera. The digital back monitored the camera body battery current to sync the image sensor exposure to the film body shutter. Digital images were stored on

2888-974: The London-based printing startup Kite. On 2 April 2019, Canon introduces two new UHDgc 2/3-inch Portable Zoom Lenses designed For 4K UHD Broadcast Cameras. In July 2020, Canon recorded its first ever quarterly loss due to the COVID-19 pandemic. In September 2020, Fujitsu announced that it would provide Canon with a Fujitsu Supercomputer PRIMEHPC FX1000 unit, to assist with its no-prototype development manufacturing initiative. In December 2020, Canon concluded its photographic-equipment print-ad series named "Wildlife as Canon Sees It". This series of ads began in 1981 in National Geographic magazine. In October 2023, Canon introduced its new nanoimprint lithography manufacturing systems, which it claims are simpler and more affordable than ASML 's extreme ultraviolet lithography systems. The system prints

2964-602: The RC-701. The RC series was followed by the PowerShot and Digital IXUS series of digital cameras. Canon also developed the EOS series of digital single-lens reflex cameras (DSLR) which includes high-end professional models. Due to consumers switching from compact cameras to smartphones , Canon's Q1 2013 operating profit fell 34 percent year-on-year. Canon produces a range of high-output flash units for its DSLR cameras, including

3040-501: The Still" contest that asked filmmakers to collectively shoot a short film in 8 chapters, with each chapter being shot over a short period of time and a winner was determined for each chapter. After 7 chapters the winners collaborated to shoot the final chapter of the story. Due to the affordability and convenient size of HDSLRs compared with professional movie cameras, The Avengers used five Canon EOS 5D Mark II and two Canon 7D to shoot

3116-466: The T1i itself. Other types of HDSLRs found their distinct application in the field of documentary and ethnographic filmmaking, especially due to their affordability, technical and aesthetical features, and their ability to make observation highly intimate. An increased number of films, television shows, and other productions are utilizing the quickly improving features. One such project was Canon's "Story Beyond

3192-514: The XEED SX50 LCD projector. Canon introduced its first high-definition camcorder in 2005. In November 2009, Canon made a €730 million (US$ 1.1 billion) all-cash offer for the Dutch printer maker Océ . Canon had acquired majority ownership of Océ by March 2010, and completed the acquisition of 100% of shares in Océ by the end of 2011. In 2010, Canon acquired Tereck Office Solutions, Inc. On 16 March 2010, Canon announced that it

3268-653: The brand's first professional digital body. In 2003, Canon introduced the 6.3- megapixel EOS 300D SLR camera (known in the United States and Canada as the Digital Rebel and in Japan as the Kiss Digital) with an MSRP of US$ 999, aimed at the consumer market. Its commercial success encouraged other manufacturers to produce competing digital SLRs, lowering entry costs and allowing more amateur photographers to purchase DSLRs. In 2004, Konica Minolta released

3344-441: The camera market entirely. Konica Minolta 's line of DSLRs was purchased by Sony. Like SLRs, DSLRs typically use interchangeable lenses with a proprietary lens mount . A movable mechanical mirror system is switched down (to precisely a 45-degree angle) to direct light from the lens over a matte focusing screen via a condenser lens and a pentaprism / pentamirror to an optical viewfinder eyepiece. Most entry-level DSLRs use

3420-524: The camera. A method to prevent dust from entering the chamber by using a "dust cover" filter right behind the lens mount was used by Sigma in its first DSLR, the Sigma SD9 , in 2002. Olympus used a built-in sensor cleaning mechanism in its first DSLR that had a sensor exposed to air, the Olympus E-1 , in 2003 (all previous models each had a non-interchangeable lens, preventing direct exposure of

3496-556: The company Precision Optical Instruments, Co., Ltd. in 1937. During its early years, the company did not have any facilities to produce its own optical glass, and its first cameras incorporated Nikkor lenses from Nippon Kogaku K.K. (the later Nikon Corporation ). Between 1933 and 1936, 'The Kwanon', a copy of the Leica design, Japan's first 35 mm focal-plane-shutter camera, was developed in prototype form. In 1940 Canon developed Japan's first indirect X-ray camera. Canon introduced

3572-1073: The desired circuit pattern onto the silicon wafer bypassing photolithography and can produce circuits equivalent to 5  nm scale. Canon's products include cameras (including compact digital camera , video camera , film SLR and digital SLR ), camcorders , lenses , broadcasting equipment and solutions (such as free viewpoint solution), professional displays, projectors , manufacturing equipment (including photolithography equipment such as steppers , scanners ), printers , photocopiers , image scanners , digital microfilm scanners , fax machines , binoculars , microscopes , medical equipment (including diagnostic systems such as ultrasound , X-ray , CT and MRI scanners and ophthalmic equipment ), CCTV solutions, image sensors , calculators , high precision positioning and measurement devices (such as rotary encoders ), custom optical components, handy terminals , mixed reality systems, software, and space satellites . Canon has been manufacturing and distributing digital cameras since 1984, starting with

3648-427: The elimination of digital 'noise' produced by the imaging sensor, and price reductions to lure new customers. In June 2012, Canon announced the first DSLR to feature a touchscreen , the EOS 650D/Rebel T4i/Kiss X6i . Although this feature had been widely used on both compact cameras and mirrorless models, it had not made an appearance on a DSLR until the 650D. The DSLR market is dominated by Japanese companies, and

3724-491: The first HDSLRs to offer 1080p video at 24fps, and since then the list of models with comparable functionality has grown considerably. The rapid maturation of HDSLR cameras has sparked a revolution in digital filmmaking (referred to as "DSLR revolution" ), and the "Shot On DSLR" badge is a quickly growing phrase among independent filmmakers. Canon's North American TV advertisements featuring the Rebel T1i have been shot using

3800-506: The first SVF-SLR camera) sold in the US. It employed an SLR viewfinder and included a 2/3” format color CCD sensor with 380K pixels. It was sold along with removable 11-66mm and 50-150mm zoom lens.   Over the next five years, many other companies began selling SVF analog electronic cameras. These included the monochrome Nikon QV-1000C SVF-SLR camera, introduced in 1988, which had an F-mount for interchangeable QV Nikkor lenses. In 1986,

3876-609: The first color CCD image sensor by fabricating a red, green, and blue color filter array that was registered and bonded to the CCD. In 1975, Kodak engineer Steven Sasson built the first portable, battery-operated digital still camera, which used a zoom lens from a Kodak Super 8mm movie camera and a monochrome Fairchild 100×100 pixel CCD . The first prototype filmless SLR camera was publicly demonstrated by Sony in August 1981.  The Sony Mavica (a magnetic still video camera ) used

3952-696: The first fully electronic calculator two years earlier with the Sumlock Anita Mark 8 unit. In 1965 Canon introduced the Canon Pellix , a single lens reflex (SLR) camera with a semi-transparent stationary mirror which enabled the taking of pictures through the mirror. In 1971, Canon introduced the Canon F-1 , a high-end SLR camera, and the FD lens range . In 1976, Canon launched the Canon AE-1 ,

4028-453: The image is effectively cropped and the lens appears to have a longer focal length than its stated focal length. Most DSLR manufacturers have introduced lines of lenses with image circles optimised for the smaller sensors and focal lengths equivalent to those generally offered for existing 35  mm mount DSLRs, mostly in the wide-angle range. These lenses tend not to be completely compatible with full-frame sensors or 35  mm film because of

4104-427: The introduction of the HDSLR, including higher video resolution (such as 1080p24 ) and video bitrate, improved automatic control (autofocus) and manual exposure control, and support for formats compatible with high-definition television broadcast, Blu-ray disc mastering or Digital Cinema Initiatives (DCI).

( Japanese : キヤノン株式会社 ; Hepburn : Kyanon kabushiki gaisha ) is a Japanese multinational corporation headquartered in Ōta , Tokyo , specializing in optical, imaging, and industrial products, such as lenses , cameras , medical equipment, scanners , printers , and semiconductor manufacturing equipment. Canon has

4332-668: The market has shifted from being driven by hardware to software, and camera manufacturers have not been keeping up. Beginning in the 2010s, major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILCs). In September 2013, Olympus announced they would stop the development of DSLR cameras and focus on the development of MILCs. Nikon announced they were ending production of DSLRs in Japan in 2020, followed by similar announcements from Canon and Sony. Currently, DSLRs are widely used by consumers and professional still photographers. Well established DSLRs currently offer

4408-467: The much smaller image sensors found in the typical camcorder, the HDSLR's much larger sensor yields distinctly different image characteristics. HDSLRs can achieve much shallower depth of field and superior low-light performance. However, the low ratio of active pixels (to total pixels) is more susceptible to aliasing artifacts (such as moiré patterns ) in scenes with particular textures, and CMOS rolling shutter tends to be more severe. Furthermore, due to

4484-510: The next decade, other camera manufacturers entered the DSLR market, including Canon , Kodak , Fujifilm , Minolta (later Konica Minolta , and ultimately acquired by Sony), Pentax (whose camera division is now owned by Ricoh ), Olympus , Panasonic , Samsung , Sigma , and Sony . In January 2000, Fujifilm announced the FinePix S1 Pro , the first consumer-level DSLR. In November 2001, Canon released its 4.1-megapixel EOS-1D ,

4560-498: The original Foveon X3 sensor at 33% of full frame (although Foveon sensors since 2013 have been APS-C sized). Leica offers an "S-System" DSLR with a 30×45 mm array containing 37 million pixels. This sensor is 56% larger than a full-frame sensor. The resolution of DSLR sensors is typically measured in megapixels. More expensive cameras and cameras with larger sensors tend to have higher megapixel ratings. A larger megapixel rating does not mean higher quality. Low light sensitivity

4636-688: The overall market was less than 5%. Still, Canon maintains a great presence in the i-line stepper market. Canon introduced two MSX home computer models in 1983, the V-10 and the V-20 . Both offered just the minimum range of the MSX standards without any additional features. The V-20 was able to receive shooting data from the T90 Canon camera with the Data Memory Back T90 expansion. Canon also sold
