Digital Negative (DNG) is a patented, open, lossless raw image format developed by Adobe and used for digital photography. Adobe's license allows use without cost on the condition that the licensee prominently displays text saying it is licensed from Adobe in source and documentation, and that the license may be revoked if the licensee brings any patent action against Adobe or its affiliates related to the reading or writing of files that comply with the DNG Specification. It was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification, plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software released since the launch supports DNG.
The Pentax K10D and similar Samsung GX-10 are 10.2-megapixel digital single-lens reflex cameras launched in late 2006. They were developed in a collaboration between Pentax of Japan and Samsung of South Korea.
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.
The Canon EOS 7D is an APS-C digital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699. Among its features are an 18.0 effective megapixel CMOS sensor, HD video recording, its 8.0 frames per second continuous shooting, new viewfinder which offers 1.0X magnification and 100% coverage, 19-point auto-focus system, movie mode, and built-in Speedlite transmitter.
The Pentax K-x is a 12.4 megapixel digital single-lens reflex camera, 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.
The Ricoh GR was a series of point-and-shoot, or compact, 35 mm film cameras made by Ricoh. The chronological list of these cameras are the GR1, GR10, GR1s, GR1v and GR21. The GR name was also used for Ricoh's GR series of digital cameras.
The Nikon D7000 is a 16.2-megapixel digital single-lens reflex camera (DSLR) model announced by Nikon on September 15, 2010. It replaced the D90 as the top end consumer camera, by using much of the technology and controls from the earlier D5000, in a larger more robust body similar to the flagship D300 series. In some ways it was superior to the D300S, though for several years the two cameras were both available with the D300 positioned as the flagship in Nikon marketing materials.
The Pentax 645 is a medium format single-lens reflex system camera manufactured by Pentax. It was introduced in 1984, along with a complementary line of lenses. It captures images nominally 6 cm × 4.5 cm on 120, 220, and 70 mm film, though the actual size of the images is 56 mm × 41.5 mm.
The Pentax K-3 is a 24-megapixel Pentax high-end digital single-lens reflex camera with an APS-C sensor, announced on 7 October 2013. The Pentax K-3 is the successor to both the K-5 II and K-5 IIs models, which have a 16-megapixel sensor. The K-5 II had an optical low pass filter or anti-aliasing (AA) filter that can prevent the appearance of moire patterning on the captured image. This filter reduces the sharpness of the image, so Pentax also produced the K-5 IIs which omitted this filter. In the K-3, Pentax obviated the need for providing two separate models by including a selectable AA filter "simulator". This mechanism vibrates the sensor when switched on, slightly blurring the image in a way that replaces the function of the optical AA filter, providing the same benefit as the filter in the K-5 II and other cameras with an optical AA filter. When the AA simulator is disabled, the sensor records a sharper image, as in the K-5 IIs.
The Pentax 645Z is a professional medium format digital SLR camera announced by Ricoh on April 15, 2014. While it shares its sensor with the Phase One IQ250 and Hasselblad H5Dc, it retails at less than a third of the price of these. In 2015, the 645Z won the TIPA Award for the Best Medium Format Camera.
The Canon EOS 7D Mark II is a professional digital single-lens reflex camera made by Canon. It was announced on September 15, 2014 with a suggested retail price of US$1,799. It features a 20.2 effective megapixel APS-C CMOS sensor, Full HD video recording at 60 fps, 10.0 frames per second continuous shooting, a 100% accuracy viewfinder that offers 1× magnification. It also features a 65-point auto-focus system, a built-in Speedlite transmitter and a new 150k RGB pixels + IR metering sensor. It was preceded by the Canon EOS 7D.
The Pentax K-S2 is a weather-sealed digital SLR camera announced by Ricoh on February 9, 2015. It is the first Pentax SLR to feature an articulated LCD, and it is the smallest DSLR to include this feature and also be weather-sealed. In 2015, the K-S2 won the TIPA Award in the category Best Digital SLR Advanced.
An action camera or action cam is a digital camera designed for recording action while being immersed in it. Action cameras are therefore typically compact, rugged, and waterproof at the surface level. They typically use CMOS image sensors, and can take photos in burst mode and time-lapse mode as well as record high-definition video. Slow-motion video recording at 120 or 240 fps is also a common feature.
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 Nikon D5600 is a 24.2 megapixel upper-entry level, APS-C sensor DSLR announced by Nikon on November 10, 2016, as the successor of the D5500. The camera has an F-mount.
