A digital camera, also called a digicam, is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
The Foveon X3 sensor is a digital camera image sensor designed by Foveon, Inc., and manufactured by Dongbu Electronics. It uses an array of photosites that consist of three vertically stacked photodiodes. Each of the three stacked photodiodes has a different spectral sensitivity, allowing it to respond differently to different wavelengths. The signals from the three photodiodes are then processed as additive color data that are transformed to a standard RGB color space. In the late 1970s, a similar color sensor having three stacked photo detectors at each pixel location, with different spectral responses due to the differential absorption of light by the semiconductor, had been developed and patented by Kodak.
The Canon EOS 20D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on 19 August 2004 at a recommended retail price of US$1,499. It is the successor of the EOS 10D, and was succeeded by the EOS 30D in August 2006. It accepts EF and EF-S lenses and uses an APS-C sized image sensor.
A digital single-lens reflex camera is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
Sigma Corporation is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high-quality lenses and other accessories that are compatible with the cameras produced by other companies.
The Sigma SD9 is a digital single-lens reflex camera (DSLR) produced by the Sigma Corporation of Japan. The camera was launched at the Photo Marketing Association Annual Show on February 18, 2002. It was Sigma's first digital camera, and was the first production camera to use the unique Foveon X3 image sensor, which reads full color at each pixel site. Other sensors detect only one color at each site and interpolate to produce a full-color image.
Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing. It is a form of digital imaging based on gathering visible light.
The FujifilmFinePix F series is a line of compact digital cameras that was known for its low-light performance in 2005, with relatively low image noise and natural colors even at high ISO settings. With its relatively large, but moderate resolution Super CCD sensors, it concentrated on image quality, and low-light shooting without flash, which was mostly restricted to prosumer models at the time.
The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan. It is fitted with a Sigma SA mount which takes Sigma SA lenses.
This article details lensesfor single-lens reflex and digital single-lens reflex cameras. The emphasis is on modern lenses for 35 mm film SLRs and for "full-frame" DSLRs with sensor sizes less than or equal to 35 mm.
The Sigma DP1 was a high-end compact digital camera introduced by the Sigma Corporation. It featured a 14-megapixel Foveon X3 sensor, a fixed 16.6 mm F4.0 lens, a 2.5-inch (64 mm) LCD and a pop-up flash. It was the first "compact" camera that featured an APS-C sized sensor, a feature that Sigma claimed would result in DSLR quality images from a small, pocketable camera.
The Nikon D700 is a professional-grade full-frame digital single-lens reflex camera introduced by the Nikon Corporation in July 2008 and manufactured in Japan. It uses the same 12.1-megapixel "FX" CMOS image sensor as the Nikon D3, and is Nikon's second full-frame digital SLR camera.
The Panasonic Lumix DMC-GH1 is a digital mirrorless interchangeable lens camera adhering to the Olympus and Panasonic developed Micro Four Thirds System (MFT) system design standard. Panasonic classified the GH1 as a hybrid stills/video camera and the GH1 was introduced and marketed as a higher end camera than Panasonic's first MFT camera, the stills only, non-video capable Lumix DMC-G1.
The Sigma DP2 is a high-end compact digital camera introduced by the Sigma Corporation. It features a 14-megapixel Foveon X3 sensor, the same sensor used in its predecessor, the Sigma DP1 and in the Sigma SD14 DSLR, a fixed 24.2mm f/2.8 lens, a 2.5” LCD and a pop-up flash.
The Nikon D3000 is a 10.2-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on 30 July 2009. It replaces the D40 as Nikon's entry level DSLR. It features a 3.0-inch 230,000-dot resolution LCD monitor, CCD sensor with ISO 100–1600 and 3D tracking Multi-CAM1000 11-point AF system which makes it quite similar to the Nikon D200 in these main parts. Initially priced with $599 MSRP, actual prices are much lower.
The Fujifilm FinePix S200EXR is a digital bridge camera from Fujifilm introduced in July 2009.
The Sigma SD15 is an updated version of Sigma SD14 DSLR produced by the Sigma Corporation of Japan and featuring the improved TRUE II image processing engine, but with the same image sensor as its predecessor. As such, the SD15 features the 4.7 MP Foveon X3 sensor. After having showcased the camera in photokina 2008 and officially introduced during PMA 2010, it finally began shipping in June 2010. It is Sigma's fourth DSLR since the SD9 from 2002.
Canon EOS 1100D is a 12.2-megapixel digital single-lens reflex camera announced by Canon on 7 February 2011. It is known as the EOS Kiss X50 in Japan and the EOS Rebel T3 in the Americas. The 1100D is Canon's most basic entry-level DSLR, and introduces movie mode to other entry level DSLRs. It replaced the 1000D and is also the only Canon EOS model currently in production that is not made in Japan but in Taiwan, aside from the EOS Rebel T4i.
The Nikon D5100 is a 16.2-megapixel DX-format DSLR F-mount camera announced by Nikon on April 5, 2011. It features the same 16.2-megapixel CMOS sensor as the D7000 with 14-bit depth, while delivering Full HD 1080p video mode at either 24, 25 or 30 fps. The D5100 is the first Nikon DSLR to offer 1080p video at a choice of frame rates; previous Nikon DSLRs that recorded 1080p only did so at 24 fps. It replaced the D5000 and was replaced by the D5200.
The Nikon D3200 is a 24.2-megapixel DX format DSLR Nikon F-mount camera officially launched by Nikon on April 19, 2012. It is marketed as an entry-level DSLR camera for beginners and experienced DSLR hobbyists who are ready for more advanced specs and performance.
