Hoya Corporation (Hoya株式会社, Hōya Kabushiki-gaisha) is a Japanese company manufacturing optical products such as photomasks, photomask blanks and hard disk drive platters, contact lenses and eyeglass lenses[ clarification needed ] for the health-care market, [4] medical photonics, [5] lasers, photographic filters, and software. Hoya Corporation is one of the Forbes Global 2000 Leading Companies [6] and Industry Week 1000 Company. [7]


Hoya acquired the camera company Pentax in 2007, for the price of US$1 billion, about 10% more than Pentax was valued at the time [ citation needed ]. In June 2010 the grandson of the corporation's founder Yutaka Yamanaka [8] proposed changes to the Board of Directors to prevent what he called such "mistakes" from happening again. [9] [10]

On October 1, 2011, Hoya sold its Pentax camera business to Ricoh. [11] [12]

History of Hoya-Pentax merger

Hoya discussed a merger with Pentax into Hoya Pentax HD Corporation during 2007. Hoya's primary goal was to strengthen its medical-related business by taking advantage of Pentax's technologies and expertise in the field of endoscopes, intraocular lenses, surgical loupes, biocompatible ceramics, etc. It was speculated that Pentax's camera business could be sold off after the merger. The merger was initially intended to be completed by October 1, 2007. [13] However, Pentax management decided to not pursue the originally planned share swap, and other options for a merger were discussed. [14] On May 25, the Pentax board of directors accepted Hoya's offer for a merger. [15] On August 6, 2007, Hoya completed a friendly takeover bid for Pentax and acquired 90.59% of the company. [16] On October 29, 2007, Hoya and Pentax announced that Pentax, as the company ceasing to exist, will merge with and into Hoya on March 31, 2008. [17]

The acquired Pentax surveying instrument business (later IT Asahi Co., Ltd.) and camera business (now Pentax Ricoh Imaging Co., Ltd.) were sold to Taiwan Instrument Co., Ltd. in 2009 and Ricoh Co., Ltd. in 2011, respectively.


On July 13, 2017, it was announced that the HOYA had acquired ReadSpeaker. ReadSpeaker was founded in 1999 and headquartered in Huis ter Heide, Utrecht in the Netherlands at the time of the acquisition. [18] ReadSpeaker is a text-to-speech technology that allows users to highlight words that are being spoken, and users can save the speech in an MP3 format. [19] It has been used to transform websites to speech. The International Herald Tribune employed the tool to turn into podcasts the stories it publishes online. [20] In a paper for the 2016 International Conference on Software Process Improvement, José Ortega and his coauthors said, ReadSpeaker "works 100% online, is a good reference but is commercial and costs". [21]

Business ethics and corporate social responsibility

In 2008, the glass disk subsidiary in Thailand was involved in a labour dispute. After the involvement of some customers, the dismissed workers were reinstated, and both management and union accepted to participate in harmonious communication. [22]

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.

Pentax K-7

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.

Mirrorless interchangeable-lens camera Compact camera with a user-removable and replaceable lens

A mirrorless interchangeable-lens camera (MILC) or simply mirrorless camera, also called digital single lens mirrorless (DSLM), is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount.

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 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 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.

Pentax K-3

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.
