Cine Lens
Cine lenses or cinema lenses are lenses that are designed especially for cinematography, and whose main distinguishing feature from conventional photographic lenses is the "clickless" or "declicked" aperture ring. Markings on the aperture ring indicate T-stops rather than f-stops as used in still photography. Furthermore, it is a desirable characteristic for cine lenses to occupy the same form factor as each other so as to be readily interchangeable and identical in operation. This particularly applies to lenses with different focal lengths. In order to maximise interchangeability, lenses within a series of cine lenses are often identical in transmittance of light (maximum T-stop). Anamorphic lenses for cinematography may also be classified as cine lenses.

Photographic Lenses
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Sigma Corp
Sigma (; uppercase Σ, lowercase σ, lowercase in word-final position ς; grc-gre, σίγμα) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In ' (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end. The Latin letter S derives from sigma while the Cyrillic letter Es derives from a lunate form of this letter. History The shape (Σς) and alphabetic position of sigma is derived from the Phoenician letter ( ''shin''). Sigma's original name may have been ''san'', but due to the complicated early history of the Greek epichoric alphabets, ''san'' came to be identified as a separate letter in the Greek alphabet, represented as Ϻ. Herodotus reports that "san" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leica Camera
Leica Camera AG () is a German company that manufactures cameras, optical lenses, photographic lenses, binoculars, Telescopic sight, rifle scopes and microscopes. The company was founded by Ernst Leitz in 1869 (Ernst Leitz Wetzlar), in Wetzlar, Germany. In 1986, the Leitz company changed its name to Leica, due to the fame of the Leica trade-name. The name Leica is derived from the first three letters of the founder's surname (Leitz) and the first two of the word camera: lei-ca (LEItz CAmera). At this time, Leica relocated its factory from Wetzlar to the nearby town of Solms. Leica Camera AG is 55% owned by Austrian investment firm ACM Projektentwicklung GmbH, and 45% owned by The Blackstone Group which licenses the Leica brand name from the Danaher Corporation-owned Leica Microsystems GmbH. History From the year 1907 to the 1950s, the buildings that formed Leica factory were built on Ernst Leitz Street in Wetzlar, and remained until 1986, when the factory was moved to th ...

Cooke Optics
Cooke Optics Ltd. is a camera lens manufacturing company based in Leicester. Administratively speaking, Cooke Optics is a spin-off of the company Taylor-Hobson. However, Taylor-Hobson used to be a lens manufacturer and Cooke lenses used to be its sole activity before Taylor-Hobson moved to the market of metrology instruments. Hence the foundation of Cooke Optics can be regarded as the foundation of Taylor, Taylor and Hobson (TTH) in 1886, and Cooke Optics can be regarded as the successor of the original Taylor, Taylor and Hobson business. The name Cooke originally came from the company T. Cooke & Sons of York, a manufacturer of telescopes. The optical manager of that company, H. Dennis Taylor (no relation), devised the Cooke triplet lens in the 1890s. Cooke of York was not interested in the manufacture of camera lenses, and licensed this design and others to TTH. Subsequently many of TTH's own designs, though unconnected with Cooke of York, also carried the Cooke brand. The Cook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinematography
Cinematography (from ancient Greek κίνημα, ''kìnema'' "movement" and γράφειν, ''gràphein'' "to write") is the art of motion picture (and more recently, electronic video camera) photography. Cinematographers use a lens to focus reflected light from objects into a real image that is transferred to some image sensor or light-sensitive material inside a movie camera. These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in the image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically " developed" into a visible image. The images on the film stock are projected for viewing the same motion picture. Cinematography finds uses in many fields of ...
