A camera lens is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Carl Zeiss AG, branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe and Otto Schott he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue in almost 50 countries, has 30 production sites and around 25 development sites worldwide.
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
Arriscope is a line of anamorphic lenses especially for Arriflex developed by Germany's Isco Optic. ArriScope and ArriVision are a form of the CinemaScope/Panavision process with an aspect ratio of 2.39:1.
Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger than average maximum aperture is called a "fast lens" because it can achieve the same exposure as an average lens with a faster shutter speed. Conversely, a smaller maximum aperture is "slow" because it delivers less light intensity and requires a slower (longer) shutter speed.
Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. The word anamorphic and its derivatives stem from the Greek anamorphoo, compound of morphé with the prefix aná. In the late 1990s and 2000s, anamorphic lost popularity in comparison to "flat" formats such as Super 35 with the advent of digital intermediates; however, in the years since digital cinema cameras and projectors have become commonplace, anamorphic has experienced a considerable resurgence of popularity, due in large part to the higher base ISO sensitivity of digital sensors, which facilitates shooting at smaller apertures.
Pierre Angénieux was a French engineer and optician, one of the inventors of the modern zoom lenses, and famous for introducing the Angénieux retrofocus.
The E-mount is a lens mount designed by Sony for their NEX and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's α mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:

The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras.
Angénieux is a French manufacturer of photographic and cinematographic lenses. The main markets are cinema, television, space travel and medicine. The company is part of the Thales Group, which represents Angénieux in 48 countries. The company is headquartered in Saint-Héand, near Saint-Étienne in France.
The Canon RF lens mount is an interchangeable-lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP. The RF mount was announced in September 2018. In May 2022, Canon announced APS-C EOS R cameras and RF-S lenses designed for these cameras.
Horace William Lee was an optical designer responsible for developing multiple influential lens designs, including the Opic (1920), an asymmetric large-aperture double Gauss lens, and the inverted telephoto wide-angle lens (1930), while working for the English optics firm Taylor, Taylor & Hobson (TT&H), which manufactured lenses in Leicester under the Cooke brand. Lee's designs helped to develop the modern cinematography industry, with high-speed lenses enabling sound synchronization, and the inverted telephoto providing enough space for a beam-splitter apparatus to capture color.
