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.
The Canon PowerShot G is a series of digital cameras introduced by Canon in its PowerShot line in 2000. The G series cameras are Canon's flagship compact models aimed at photography enthusiasts desiring more flexibility than a typical point-and-shoot without the bulk of a digital single-lens reflex camera.
The K110D is Pentax's entry-level DSLR. It has 6.1 Megapixels. The K110D is youngest of three sibling cameras in terms of specifications. It differs from the K100D only in lacking an in-body image stabilization system.
The Pentax K20D and its clone, the Samsung GX-20, are 14.6 megapixel digital single-lens reflex cameras manufactured by Pentax that were announced on January 23, 2008. The K20D was available in the U.S. market from February 2008 through autumn 2009.
This article discusses the cameras – mainly 35 mm SLRs – manufactured by Pentax Ricoh Imaging Corp. and its predecessors, Pentax Corporation and Asahi Optical Co., Ltd.. Pentax must not be confused with Pentax 6x7 or Pentax 67 which are 120 medium format 6x7cm film cameras.
Pentax lenses were first badged as Takumar. The Takumar branded lenses were well respected for their line of Super Takumar, which designated the high performance coating applied to the lens as well as the optical formulas used to make them. The majority of the industry at the time was still satisfied with the variations of the "plumb" coating process and later some of the two and three layer processes as well. Asahi Pentax soon introduced the Takumar Super-Multi-Coated line of lenses which was a 7 layer process as the industry had just caught up with similar forms of 5 layer multi-coated optics. Eventually Asahi Optical and Pentax slowly shifted much of their lens production under the Pentax name and transitioned some of the successful designs that were first introduced under the Takumar name to use Asahi/Pentax badging as well as beginning to use the "smc" abbreviation. Eventually the Asahi partnership disappeared and the Pentax name became solely used. Pentax lenses saw many feature changes to answer the market, such as: incorporating "Auto-Aperture" with the M42, the light weight and compactness with the 'M' series, Aperture Priority overrides with the 'A' series, and Auto-Focus with the 'F' series. Modern Pentax lenses for digital SLR cameras have seen the elimination of the aperture ring completely as found on Pentax DA and D-FA series lenses. They use the Pentax KAF mount. All of these lenses have an autofocus feature, either operated from the camera body or from an internal SDM motor. Pentax compatible lenses are also made by third-party companies.
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 Nikon D300S is a 12.3-megapixel DX format digital single-lens reflex camera (DSLR) announced by Nikon on 30 July 2009. It replaced the D300 as Nikon's flagship DX format DSLR adding HD video recording. It has some similarities to the Nikon D700, with the same resolution, but has a smaller, higher-density sensor. The D300s was superseded by the Nikon D500, announced on January 5, 2016.
The Pentax K-x is a 12.4 megapixel digital single-lens reflex camera, which was announced on September 16, 2009. The Pentax K-x uses a Sony Exmor sensor. In some cases it even approaches the quality produced by full-frame DSLRs like the Nikon D700 and the Canon 5DMkII, both with larger sensors. The Pentax K-x is suitable for low light conditions for both still and video photography.
A mirrorless camera is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs).
The Pentax K-5 is a 16.3-megapixel digital single-lens reflex camera, announced on September 20, 2010. It began shipping in mid-October 2010 and it was replaced by the Pentax K-5 II in the third quarter of 2012.
The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q. As of September 2012, it was the world's smallest, lightest interchangeable lens digital camera. The first models used a 1/2.3" back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor. The Q system is now discontinued.
The Fujifilm X100 is a series of digital compact cameras with a fixed prime lens. Originally part of the FinePix line, then becoming a member of the X series from Fujifilm, the X100 series includes the FinePix X100, X100S, X100T, X100F, X100V, and X100VI. They each have a large image sensor and a 23 mm lens. All six cameras have received generally positive reviews.
The Canon EOS 6D is a 20.2-megapixel full-frame CMOS digital single-lens reflex camera made by Canon.
The Pentax Q-S1 is a compact digital mirrorless interchangeable lens camera announced by Ricoh under the Pentax brand on August 4, 2014. It replaces the Pentax Q7, and is part of Pentax' Q system, the most compact digital interchangeable lens camera system as of September 2014, with crop factors ranging from 4.6 to 5.6.
The Pentax K-S1 is a midrange DSLR camera announced by Ricoh on August 27, 2014. It has a 20 megapixel sensor — new to the Pentax line-up — and an anti-aliasing filter simulator as previously seen in the Pentax K-3. Also adopted from the K-3 is compatibility with the Pentax FluCard, which allows wireless tethered shooting and wireless download of images from the camera.
The Ricoh GR is a series of point-and-shoot, or compact, digital cameras made by Ricoh. The GR name was previously used for Ricoh's GR series of film cameras. Like the GR film cameras and Fujifilm X70, the GR digital cameras use metal bodies fitted with bright, permanently-attached prime lenses. In general, the GR digital cameras follow the precedent set by the original GR1 (1996) with lenses that provide a field of view equivalent to a 28 mm wide angle lens on a 35mm film camera.
The Fujifilm X-Pro2 is a mirrorless interchangeable-lens digital camera announced in January 2016. It is part of Fujifilm's X-Series of cameras, the successor to the X-Pro1. Sales began on 3 March 2016.
The Pentax K-1 is the first production Pentax full-frame digital SLR camera. As the flagship model of the Pentax K-mount system, it includes several new and improved features, including a five-axis SR II in-body image stabilization system, newly designed flexible tilt articulating screen mounted on four metal struts allowing for rotation about the optical axis in addition to upward and downward tilt, and improved autofocus and metering systems.
The Pentax KP is a 24 megapixel compact APS-C AA-filterless digital SLR camera announced by Ricoh on January 25, 2017. It features a PRIME IV image processor with an "image accelerator unit" that supports its operation up to ISO 819,200. It has a 1/6000s conventional and 1/24,000s electronic shutter. In terms of bracketing modes, it adds depth of field and shutter speed bracketing. The Pentax KP uses the Pentax K-mount interchangeable lens system.
