When was dslr invented

Hello friends and viewers, this blog is about the history of DSLR. These are the first DSLR manufactured. Full form of DSLR is Digit Single Lens Reflector. 

Kodak DCS 100, based on a Nikon F3 body with Digital Storage Unit, released in May 1991

Now, we are talk about the invention. In 1969 Willard S. Boyle and George E. Smith invented the first successful imaging technology using a digital sensor, a CCD (Charge-Coupled Device). CCD would allow the rapid development of digital photography. For their contribution to digital photography Boyle and Smith were awarded the Nobel Prize for Physics in 2009.

In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild100×100 pixel CCD.

On August 25, 1981 Sony unveiled a prototype of the Sony Mavica. This camera was an analog electronic camera that featured interchangeable lenses and a SLR viewfinder.

In 1986, 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 the first 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 a tethered hard drive and processed for histogram feedback to the user. This first camera was created for the U.S. Government, and was followed by several other models intended for government use, and eventually the first commercial DSLR, launched by Kodak 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 the Nikon E3/E3S, with the E3S released in December 1999.

In 1999, Nikon announced the Nikon D1. The D1's body was similar to Nikon's professional 35 mm film SLRs, and it had the same Nikkor lens mount, allowing the D1 to use Nikon's existing line of AI/AIS manual-focus and AF lenses. Although Nikon and other manufacturers had produced digital SLR cameras for several years prior, the D1 was the first professional digital SLR that displaced Kodak's then-undisputed reign over the professional market.

Over 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, the brand's first professional digital body. In 2003, Canon introduced the 6.3 megapixel EOS 300DSLR 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 the Konica Minolta Maxxum 7D, the first DSLR with in-body image stabilization which later on 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 offer cameras with this functionality.

Since then the number of megapixels in imaging sensors have increased steadily, with most companies focusing on high ISO performance, speed of focus, higher frame rates, 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 in a DSLR until the 650D.

Market shareEdit

The DSLR market is dominated by Japanese companies and the top five manufacturers are Japanese: Canon, Nikon, Olympus, Pentax, and Sony. Other manufacturers of DSLRs include Mamiya, Sigma, Leica (German), and Hasselblad (Swedish).

In 2007, Canon edged out Nikon with 41% of worldwide sales to the latter's 40%, followed by Sony and Olympus each with approximately 6% market share.In the Japanese domestic market, Nikon captured 43.3% to Canon's 39.9%, with Pentax 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 profits. For Canon, their DSLRs brought in four times the profits from compact digital cameras, while Nikon earned more from DSLRs and lenses than with any other product. Olympus and Panasonic have since exited the DSLR market and now focus on producing mirrorless cameras.

In 2013, after a decade of double-digit growth, DSLR (along with MILC) sales are 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, the market has shifted from being driven by hardware to software, and camera manufacturers have not been keeping up.

To illustrate the trend, in September 2013 Olympus announced they would stop development of DSLR cameras and will focus on the development of MILC. 

Present-day modelsEdit

Currently DSLRs are widely used by consumers and professional still photographers. Well established DSLRs currently offer a larger variety of dedicated lenses and other photography 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, Samsungpreviously produced DSLRs, but now either offer non-DSLR systems or have left the camera market entirely. Konica Minolta's line of DSLRs was purchased by Sony.

• Canon's current 2018 EOS digital line includes the Canon EOS 1300D/Rebel T6, 200D/SL2, 800D/T7i, 77D, 80D, 7D Mark II, 6D Mark II, 5D Mark IV, 5Ds and 5Ds R and the 1D X Mark II. All Canon DSLRs with three- and four-digit model numbers, as well as the 7D Mark II, have APS-C sensors. The 6D, 5D series, and 1D X are full-frame. As of 2018, all current Canon DSLRs use CMOS sensors.
• Nikon has a broad line of DSLRs, most in direct competition with Canon's offerings, including the D3400, D5600, D7500 and D500 with APS-C sensors, and the D610, D750, D850, D5, D3X and the Df with full-frame sensors.
• Leica produces the S2, a medium format DSLR.
• Pentax currently offers the K-3 II, K-S2 and K-S1, all of which use an APS-C sensor.These models offer extensive backwards compatibility, accepting all Pentax K mount lenses, which started being made in 1975. Pentax also offers the Pentax 645Z, which is a medium format camera, and, like Pentax' medium format film cameras, compatible with Pentax' 645 system lenses. In 2016, Pentax introduced its first full-frame DSLR, the Pentax K-1, with the successor K-1 Mark II announced in 2018.
• Sigma produces DSLRs using the Foveon X3 sensor, rather than the conventional Bayer sensor. This is claimed to give higher colour resolution, although headline pixel counts are lower than conventional Bayer-sensor cameras. It currently offers the entry-level SD15 and the professional SD1. Sigma is the only DSLR manufacturer which sells lenses for other brands' lens mounts.
• Sony has modified the DSLR formula in favor of single-lens translucent (SLT) cameras,which are still technically DSLRs, but feature a fixed mirror that allows most light through to the sensor while reflecting some light to the autofocus sensor. Sony's SLTs feature full-time phase detection autofocusduring video recording as well as continuous shooting of up to 12 frame/s. The α series, whether traditional SLRs or SLTs, offers in-body sensor-shift image stabilization and retains the Minolta AF lens mount. As of July 2017, the lineup included the Alpha 68, the semipro Alpha 77 II, and the professional full-frame Alpha 99 II. The translucent (transmissive) fixed mirror allows 70 percent of the light to pass through onto the imaging sensor, meaning a 1/3rd stop loss light, but the rest of this light is continuously reflected onto the camera's phase detection AF sensor for fast autofocus for both the viewfinder and live view on the rear screen, even during video and continuous shooting. The reduced number of moving parts also makes for faster shooting speeds for its class. This arrangement means that the SLT cameras use an electronic viewfinder as opposed to an optical viewfinder, which some consider a disadvantage, but does have the advantage of a live preview of the shot with current settings, anything displayed on the rear screen is displayed on the viewfinder, and handles bright situations well.
