Contax N Digital
The Contax N Digital was a six-megapixel digital SLR camera produced by Contax in Japan. The camera was announced in late 2000, and began to be sold in spring 2002, after several delays. The camera received mixed reviews from the press, and was withdrawn from the market within a year of its introduction. It was noteworthy for being the first full-frame digital SLR, with an imaging chip the full size of a 135 film frame. All previous digital SLRs had a smaller sensor, giving a cropped view (see magnification factor). The imaging sensor was a Philips FTF3020-C, which had previously been used in the Jenoptik ''Eyelike'' medium format digital back. Pentax also planned to use the sensor in a full-frame digital SLR, the Pentax MZ-D, but abandoned work on the prototype in late 2001. The sensor featured ISO settings as low as ISO 25, but the reviews noted that it had a relatively high noise level above ISO 100. The next full-frame digital SLRs were the Canon EOS-1Ds of late 2002, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Single-lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...

Pentax MZ-D
The Pentax MZ-D, also known by its internal code name of MR-52, was a prototype digital single-lens reflex camera from Pentax of Japan. It was announced at photokina in September 2000 and was demonstrated to the press at the Photo Marketing Association (PMA) show in January 2001. In October 2001, Pentax cancelled the camera, stating "The cost of manufacturing the prototype SLR 6-megapixel digital camera meant it was not a viable product for our target market" The MZ-D was derived from the top-of-the-line Pentax film camera of the time, the MZ-S. To give space for the extra circuitry and battery power required for a digital camera, the MZ-D shape incorporated the size and shape of the MZ-S' optional battery booster and vertical grip. It also shared the Pentax KAF2 lens mount. The MZ-D was to use the same 6 megapixel (3072×2048) full 135 film frame sized (24×36 mm) CCD (model FTF3020-C) from Philips that was used by the Contax N Digital The Contax N Digital was a si ...

Contax DSLR Cameras
Contax (stylised as CONTAX in the Kyocera era) began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant. Historical overview While the firm of Ernst Leitz of Wetzlar established the 24 mm × 36 mm negative format on perforated 35 mm movie film as a viable photographic system, Zeiss Ikon of Dresden decided to produce a competitor designed to be superior in every way. The name Contax was ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyocera
is a Japanese multinational ceramics and electronics manufacturer headquartered in Kyoto, Japan. It was founded as in 1959 by Kazuo Inamori and renamed in 1982. It manufactures industrial ceramics, solar power generating systems, telecommunications equipment, office document imaging equipment, electronic components, semiconductor packages, cutting tools, and components for medical and dental implant systems. History Origins to 2000 Kyocera's original product was a ceramic insulator known as a "kelcima" for use in television picture tubes. The company quickly adapted its technologies to produce an expanding range of ceramic components for electronic and structural applications. In the 1960s, as the NASA space program, the birth of Silicon Valley and the advancement of computer technology created demand for semiconductor integrated circuits (ICs), Kyocera developed ceramic semiconductor packages that remain among its core product lines today. In the mid-1970s, Kyocera began e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Zeiss
Carl Zeiss (; 11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman. In 1846 he founded his workshop, which is still in business as Carl Zeiss AG. Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world. Birth and family His father Johann Gottfried August Zeiss (1785–1849) was born in Rastenberg, where his forefathers had worked as artisans for over 100 years. August moved with his parents to Buttstädt, a small regional capital north of Weimar, where he married Johanna Antoinette Friederike Schmith (1786–1856). Car ...
