Pentax is a brand of optical equipment used by Hoya Corporation and Ricoh in various market segments. Earlier, before the acquisition in 2008, it was the Japanese company Pentax Corporation, a manufacturer of optical equipment. On March 31, 2008, the company ceased to be independent and became part of Hoya Corporation as PENTAX Imaging Systems Division, retaining the trademark and continuing production under the Pentax brand. Later, on July 1, 2011, a deal was announced between the Hoya Corporation and Ricoh, which would transfer the Pentax Imaging Systems Division of consumer photography equipment to Ricoh on October 1, 2011.

PENTAX RICOH

Pentax brand produces cameras, lenses, optical instruments such as binoculars, microscopes, telescopes, endoscopes, glasses for glasses and the like.

In 2010, the Pentax brand closed the top ten manufacturers in the photo equipment market, having a market share of 1,5% (having decreased from 1,7% in 2009). Among the manufacturers of SLR cameras, the brand is not among the top three, behind Canon, Nikon and Sony.

Historical information

The company was founded in 1919 under the name "Asahi Optical Joint Stock Co." and was engaged in the production of eyeglass lenses. In 1938, it changed its name to Asahi Optical Co., Ltd. and its product range expanded to include lenses for photography and cinema. During World War II, production was largely reoriented to fulfill military orders. After the war, it was closed, but production began again in 1948. During this time, Asahi Optical was engaged in the production of binoculars and lenses for the manufacturers of photographic equipment, which later became Konica and Minolta.

In 1952, Asahi Optical introduced its first camera, the Asahiflex I, which was the first 35mm single-lens reflex camera made entirely in Japan. The next (1954) camera, the Asahiflex II, thanks to an innovation such as a quick-return mirror, sharply popularized formerly obsolete SLR cameras as such, and the firm gained a strong position as an industry pioneer (see Asahiflex II for more details). Following this camera, the Asahi Pentax was launched into production, to which the pentaprism, which later became the standard, was added. The Pentax trademark in 1957 was only the name of a specific model of a SLR camera manufactured by Asahi Optical. Until 1954, this brand, composed of the two words Pentaprism and Contax, belonged to the Dresden company VEB Zeiss-Ikon and was bought by Asahi Optical.

The company's products were exported all over the world under the brand name "Asahi Pentax", and in the USA as "Honeywell Pentax" after the name of the distributor company. The name "Pentax Corporation" was adopted in 2002.

In December 2006, a merger with Hoya Corporation was announced. The name of the new firm was to be Hoya Pentax HD Corporation. This was followed by the resignation of the President of Pentax, but the firm continued its course towards the merger.

On March 31, 2008, the company became part of the Hoya Corporation, retaining the trademark and continuing the production of Pentax cameras.

On July 1, 2011, a deal was announced between Hoya Corporation and Ricoh to transfer the Pentax Imaging Systems Division of consumer photography equipment to Ricoh on October 1, 2011.

In October 2011, the Ricoh Company announced that it had completed the takeover of Pentax Imaging Corporation and the name of the acquired company was changed to Pentax Ricoh Imaging Company. The company will develop, manufacture and market consumer optics products and services such as digital cameras and interchangeable lenses, as well as camera accessories, security camcorder products and binoculars.
