Pentax
company
Pentax Corporation (ペンタックス株式会社, Pentakkusu Kabushiki gaisha) was a Japanese camera and optical equipment manufacturer. Currently, it exists as Pentax Medical, a division of Hoya's medical endoscope business, as well as the digital and film camera brand of Ricoh Imaging Company, a subsidiary of Ricoh, and TI Asahi Co, Ltd., a manufacturer of surveying equipment.
Pentax, founded in 1919 as Asahi Kogaku Goshi Kaisha, a town workshop specializing in polishing eyeglass lenses, developed Japan's first single-lens reflex camera, the Asahiflex, in 1952. In 1938, it changed its name to Asahi Optical Co., Ltd.. In the mid-1950s, Asahi Optical Co., Ltd. acquired the German brand Pentax, and Asahi Pentax Corporation was established in Japan as a sales company. In 2002, Asahi Optical Co. changed its name to Pentax Corporation. By 2006, Pentax's domestic market share in digital cameras had declined to 4%. In 2007, Pentax was acquired by Hoya and subsequently merged with the company the following year.

Why this record matters
“Pentax” is worth following because a concise public description often conceals a longer documentary argument. Here, Pentax and company provides the most credible route into that argument.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q503673. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1919, 1952, 1938 and 2002.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
