Voigtländer Vitessa
The Vitessa was a line of 35mm compact rangefinder cameras made by Voigtländer in the 1950s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. Most of the Vitessa cameras were fixed-lens models equipped with collapsable lenses for portability. One of the later Vitessa models, the Vitessa T (1956), introduced the Deckel (DKL) bayonet mount for interchangeable photographic lenses. When sold by Voigtländer, the ''Vitessa'' line was their mid-range rangefinder camera, positioned between the professional ''Prominent'' (135) and the entry-level ''Vito'' / ''Vitomatic'' / ''Vitoret''. Cameras The original Vitessa was introduced in 1950 with a fast ''Ultron'' 50 mm lens. It was joined later by a version with a ''Color-Skopar'' 50 mm ( ''Tessar''-type) lens. Contemporary marketing materials emphasized the rapid operation of the camera: by pressing the shutter release button, positioned on the ...

Zeiss Tessar
The ''Tessar'' is a photographic lens design conceived by the German physicist Dr. Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the Zeiss ''Tessar''. Since its introduction, millions of ''Tessar'' and ''Tessar''-derived lenses have been manufactured by Zeiss and other manufacturers, and are still produced as excellent intermediate aperture lenses. The ''Tessar'' design uses four spherical lens elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative concave flint glass element cemented with a positive convex crown glass element at the rear.

Zeiss Sonnar
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture. Naming The name "Sonnar" is derived from the German word " Sonne", meaning sun. It was originally a tradename owned by in for a Tessar-like lens. Sontheim's coat of arms includes a symbol of the sun. Nettel merged with August Nagel's in 1919. The resulting AG in Stuttgart was one of the companies that merged to form the Zeiss Ikon AG in 1926. When the modern Zeiss lens was designed by Bertele, Zeiss re-used the old Nettel tradename in order to build on the sun association to emphasize on the lens' large aperture (), which was much greater than many other lenses available at the time.

Double Gauss Lens
The double Gauss lens is a compound lens used mostly in camera lenses that reduces optical aberrations over a large focal plane. Design The earliest double Gauss lens, patented by Alvan Graham Clark in 1888, consists of two symmetrically-arranged Gauss lenses. Each Gauss lens is a two-element achromatic lens with a positive meniscus lens on the object side and a negative meniscus lens on the image side. In Clark's symmetric arrangement, this makes four elements in four groups: two positive meniscus lenses on the outside with two negative meniscus lenses inside them. The symmetry of the system and the splitting of the optical power into many elements reduces the optical aberrations within the system. There are many variations of the design. Sometimes extra lens elements are added. The basic lens type is one of the most developed and used photographic lenses. The design forms the basis for many camera lenses in use today, especially the wide-aperture standard lenses used with 35& ...

Aperture
In optics, the aperture of an optical system (including a system consisting of a single lens) is the hole or opening that primarily limits light propagated through the system. More specifically, the entrance pupil as the front side image of the aperture and focal length of an optical system determine the cone angle of a bundle of rays that comes to a focus in the image plane. An optical system typically has many structures that limit ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the cone of rays that an optical system accepts (see entrance pupil). As a result, it also determines the ray cone angle and brightne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Length
The focal length of an Optics, optical system is a measure of how strongly the system converges or diverges light; it is the Multiplicative inverse, inverse of the system's optical power. A positive focal length indicates that a system Convergence (optics), converges light, while a negative focal length indicates that the system Divergence (optics), diverges light. A system with a shorter focal length bends the Ray (optics), rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially Collimated beam, collimated (parallel) rays are brought to a Focus (optics), focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In mos ...

Instamatic
: ''For the film formats associated with the ''Instamatic'' and ''Pocket Instamatic'' camera ranges, see 126 film and 110 film respectively.'' The Instamatic is a series of inexpensive, easy-to-load 126 film, 126 and 110 film, 110 cameras made by Kodak beginning in 1963. The Instamatic was immensely successful, introducing a generation to low-cost photography and spawning numerous imitators. During its heyday, the range was so ubiquitous that the Instamatic name is still frequently used as a generic trademark to refer to any inexpensive point-and-shoot camera. It is also frequently used incorrectly to describe Kodak's ''Kodamatic'' line of instant camera, instant-picture cameras. Kodak also used the Instamatic name on some Super 8 mm film, Super 8-based home-cine cameras. History Market research which showed that most consumers would be happier with more automated film loading and exposure settings led Kodak to develop the Instamatic cameras starting in the early 1950s under pr ...

126 Film
126 film is a cartridge-based film format used in still photography. It was introduced by Kodak in 1963, and is associated mainly with low-end point-and-shoot cameras, particularly Kodak's own Instamatic series of cameras. Although 126 was once very popular, it is no longer manufactured, and few photofinishers will process it. Technical details In 1963, Kodak introduced a new film, encased in a plastic cartridge, for which they re-introduced the "126" designation. (The number was originally used for the unrelated 126 roll film format from 1906 to 1949). The term "126" was intended to show that 26 mm square images were recorded, using Kodak's common 1xx film numbering system. However the image size is actually 28×28 mm, which usually was reduced to approximately 26.5×26.5 mm by masking during printing or mounting. At the nominal 28 mm square size, the image diagonal is mm, which is close to the mm diagonal of a 135 film frame (24×36&nb ...

Single-lens Reflex Camera
In photography, a single-lens reflex camera (SLR) is a type of camera that uses a mirror and prism system to allow photographers to view through the lens and see exactly what will be captured. SLRs became the dominant design for professional and consumer-level cameras throughout the late 20th century, offering interchangeable lenses, through-the-lens (TTL) metering, and precise framing. Originating in the 1930s and popularized in the 1960s and 70s, SLR technology played a crucial role in the evolution of modern photography. Although digital single-lens reflex (DSLR) cameras succeeded film-based models, the rise of Mirrorless camera, mirrorless cameras in the 2010s has led to a decline in SLR use and production. 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 and allows light to pass through to the light receptor and the im ...
