The Ricoh Company, Ltd. ( /ˈrk/ ) (株式会社リコー, Kabushiki-gaisha Rikō) is a Japanese multinational imaging and electronics company. It was founded by the now-defunct commercial division of the Institute of Physical and Chemical Research (Riken) known as the Riken Concern , on 6 February 1936 as Riken Sensitized Paper (理研感光紙, Riken Kankōshi). Ricoh's headquarters are located in Ota, Tokyo. [1]


Ricoh produces electronic products, primarily cameras and office equipment such as printers, photocopiers, fax machines, offers Software as a Service (SaaS) document management applications such as DocumentMall, RicohDocs, GlobalScan, Print&Share [2] and also offers Projectors. In the late 1990s through early 2000s, the company grew to become the largest copier manufacturer in the world. During this time, Ricoh acquired Savin, Gestetner, Lanier, Rex-Rotary, Monroe, Nashuatec, IKON and most recently IBM Printing Systems Division / Infoprint Solutions Company. Although the Monroe brand was discontinued, products continue to be marketed worldwide under the remaining brand names. In 2006, Ricoh acquired the European operations of Danka for $210 million. These operations continue as a stand-alone business unit, under the Infotec brand. [3]



The Ricoh Group has sales and support, production, and research and development operations in nearly 180 countries. It has its world headquarters in Tokyo, Japan and regional headquarters in Japan, the Americas, Europe, China, and the Asia-Pacific.

Pentax Japanese optics company and brand owned by Ricoh

Pentax is a brand name used primarily by the Japanese multinational imaging and electronics company Ricoh for DSLR cameras, lenses, sport optics, and CCTV optics. The Pentax brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses.

APS-C Image sensor format

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 31.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.

Pentax K-mount Series of camera lens mounts made by Pentax

The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.

Pentax K10D

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.

Ricoh GR Digital II

The Ricoh GR Digital II is a compact digital camera, the successor of the Ricoh GR Digital and one of a series of Ricoh GR digital cameras.

Pentax K20D

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.

Pentax K200D

The Pentax K200D is a 10.2 megapixel digital single-lens reflex camera, announced on January 24, 2008, along with the higher-end K20D. It was discontinued in December 2008, giving it the distinction of being one of the shortest-lived DSLR cameras.

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 (lens)

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.

Ricoh GXR

The Ricoh GXR is a compact digital camera first announced by Ricoh Company, Ltd, Tokyo on November 10, 2009. Unlike conventional cameras which either have a fixed lens and sensor or interchangeable lens and a fixed sensor, the GXR takes interchangeable units, each housing a lens, sensor and image processing engine. This allows each unit to have these features optimised to one another and a specific task, whereas with conventional interchangeable lens cameras, each different lens must use the same sensor and engine. The sealed units also prevent dust from reaching the sensor, which can be a problem with other cameras where the sensor is exposed whilst a lens is being changed. A significant disadvantage of this system is the extra cost involved in having to buy a whole new sensor with every new lens.

Pentax K-5 Digital camera model

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.

Pentax 645

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.

Pentax K-5 II Camera

The Pentax K-5 II is a 16.3-megapixel digital single-lens reflex camera, successor to the Pentax K-5, sharing its body shape with its two predecessors including the Pentax K-7, and making incremental improvements on the K-5.

Pentax DA 10-17mm lens

The smc Pentax-DA 10-17mm f/3.5-4.5 ED (IF) Fish-Eye lens is a fisheye zoom lens for the Pentax K-mount. It offers an up to 180 degree view, and allows quick shift focus.

Pentax Q

The Pentax Q is a mirrorless interchangeable-lens camera introduced by Pentax on June 23, 2011.

Pentax K-50

The Pentax K-50 is a 16.3-megapixel mid-level Pentax digital single-lens reflex camera, announced on 12 June 2013. It is the direct successor to the Pentax K-30 model, both of which are weather-sealed.

Ricoh GR (large sensor compact camera)

The Ricoh GR is a digital large sensor compact camera announced by Ricoh on April 17, 2013, one of a number of Ricoh GR digital cameras. It was succeeded by the Ricoh GR II in 2015 and the Ricoh GR III in 2019.

The HD Pentax-D FA* 85mm f/1.4 SDM AW lens is a professional short telephoto prime lens for the Pentax K-mount. The lens was officially announced on February 26th 2019, launched on June 25th 2020 and announced to be first shipped on June 26th 2020.
