Contax
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.

Contax II
The Contax II is a 35 mm rangefinder camera. It was released in 1936 and was the successor of the original Contax later called the Contax I. It was the first camera with a rangefinder and viewfinder combined in a single window. Its chief designer was Hubert Nerwin Hubert is a Germanic masculine given name, from ''hug'' "mind" and ''beraht'' "bright". It also occurs as a surname. Saint Hubertus or Hubert (c. 656 – 30 May 727) is the patron saint of hunters, mathematicians, opticians, and metalworkers. .... The Nettax was meant to be a cheaper alternative, it was a derivative of the Super Nettel with a rigid body and interchangeable lenses with a specific bayonet and a very limited range of lenses. The Contax ll was the impressive Zeiss response to the popularity and demand for the Leica 35mm camera. This demand for high quality 35mm picture making tools was based on portability and the increasing availability of 35mm motion picture film, packaged into spools and ...

Yashica
Yashica was a Japanese manufacturer of cameras, originally active from 1949 until 2005 when its then-owner, Kyocera, ceased production. In 2008, the Yashica name reappeared on cameras produced by the Hong Kong-based MF Jebsen Group. In 2015, trademark rights were transferred to Yashica International Company Limited and appointed 100 Enterprises International Group Co. Limited as Yashica Global Sole Agent. History The company began in December 1949 in Nagano, Japan, when the Yashima Seiki Company was founded with an initial investment of $566.Heiberg, Milton, ''The Yashica Guide, A Modern Camera Guide Series Book'', New York: Amphoto Press, , p. 10 Its eight employees originally manufactured components for electric clocks.Heiberg, p. 10 Later, they began making camera components, and by June 1953 had introduced their first complete camera, the Yashimaflex, a twin-lens reflex (TLR) medium-format camera designed for 6x6 cm medium format film.

Contax I
The Contax I, or Original Contax, is a 35 mm rangefinder camera made between 1932 and 1936 by Zeiss Ikon. The Contax I had six identifiable variants, but fundamentally identical; every aspect was designed to outperform the Leica. For instance, the removable back was for faster loading and reloading, the bayonet lens mount was designed for rapid lens interchangeability, the long-base rangefinder allowed more accurate focusing, and the vertical metal shutter not only gave a faster maximum speed but also banished the problem of shutter blinds burning. History In 1932, Zeiss Ikon of Dresden decided to produce a competitor to the Leica II, designed to be superior in every way. The name Contax was chosen after a poll among its employees. Dr. Ing. Heinz Kuppenbender was listed On patents as the inventor of this camera. But, in fact, Dr. Emanuel Goldberg was the designer of the Contax. Goldberg continued to work on this camera design until he was forced to leave Dresden in 1933 for Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hologon
The Zeiss Hologon is an ultra wide-angle f=15mm 8 triplet lens, providing a 110° angle of view for 35mm format cameras. The Hologon was originally fitted to a dedicated camera, the Zeiss Ikon Contarex Hologon in the late 1960s; as sales of that camera were poor and the Zeiss Ikon company itself was going bankrupt, an additional 225 lenses were made in Leica M mount and released for sale in 1972 as the only Zeiss-branded lenses for Leica rangefinders until the ZM line was released in 2005. The Hologon name was revived in 1994 for a recomputed f=16mm 8 lens fitted to the Contax G series of rangefinder cameras. Design The Hologon was designed by and others at Zeiss in 1966 and patented in 1972. It is a largely symmetric triplet with a fixed aperture; the original German patent application describes a lens with 120° angle of coverage and a 8 maximum aperture, while the US patent expands this to three related designs with different coverage angles and apertures (120° 8, 110° 5.6 ...

Single-lens Reflex Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Focal-plane Shutter
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. Two-curtain shutters The traditional type of focal-plane shutter in 35 mm cameras, pioneered by Leitz for use in its Leica cameras, uses two shutter curtains, made of opaque rubberised fabric, that run horizontally across the film plane. For slower shutter speeds, the first curtain opens (usually) from right to left, and after the required time with the shutter open, the second curtain closes the aperture in the same direction. When the shutter is cocked again the shutter curtains are moved back to their starting positions, ready to be released. Focal-plane shutter at low speed ''Figure 1:'' The black rectangle represents the frame aperture through which the exposure is made. It is currently covered by the first shutter curtain, shown in red. The sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. The beam reflects inside the prism ''twice'', allowing the transmission of an image through a right angle without inverting it (that is, without changing the image's handedness) as an ordinary right-angle prism or mirror would. The reflections inside the prism are not caused by total internal reflection, since the beams are incident at an angle less than the critical angle (the minimum angle for total internal reflection). Instead, the two faces are coated to provide mirror surfaces. The two opposite transmitting faces are often coated with an antireflection coating to reduce spurious reflections. The fifth face of the prism is not used optically but truncates what would otherwise be an awkward angle joining the two mirrored faces. In cameras A variant of this prism is the roof pentaprism which is commonly used in the viewfin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
135 Film
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame". ...
