Panavision is an American motion picture equipment company specializing in cameras and lenses, based in Woodland Hills, California. Formed by Robert Gottschalk as a small partnership to create anamorphic projection lenses during the widescreen boom in the 1950s, Panavision expanded its product lines to meet the demands of modern filmmakers. The company introduced its first products in 1954. Originally a provider of CinemaScope accessories, the company's line of anamorphic widescreen lenses soon became the industry leader. In 1972, Panavision helped revolutionize filmmaking with the lightweight Panaflex 35 mm movie camera. The company has introduced other groundbreaking cameras such as the Millennium XL (1999) and the digital video Genesis (2004). Panavision operates exclusively as a rental facility—the company owns its entire inventory, unlike most of its competitors. == Early history == Robert Gottschalk founded Panavision in late 1953, in partnership with Richard Moore, Meredith Nicholson, Harry Eller, Walter Wallin, and William Mann;〔Samuelson, David W. ''Panaflex Users' Manual''. Focal Press, 1990. ISBN 0-240-80267-5.〕 the company was formally incorporated in 1954. Panavision was established principally for the manufacture of anamorphic projection lenses to meet the growing demands of theaters showing CinemaScope films.〔Roudebush, James. ("Filmed in Panavision: The Ultimate Wide Screen Experience." ) ''Secrets of Home Theater and High Fidelity'' vol. 2, no. 1 (HomeTheaterHiFi.com). January 1995. Retrieved on 2007-01-19.〕 At the time of Panavision's formation, Gottschalk owned a camera shop in Westwood Village, California, where many of his customers were cinematographers.〔Samuelson, David W. "Golden Years." ''American Cinematographer'', September 2003, pp. 70–77.〕 A few years earlier, he and Moore—who worked with him in the camera shop—were experimenting with underwater photography; Gottschalk became interested in the technology of anamorphic lenses, which allowed him to get a wider field of view from his underwater camera housing.〔Henderson, Scott. "The Panavision Story." ''American Cinematographer'', April 1977.〕 The technology was created during World War I to increase the field of view on tank periscopes; the periscope image was horizontally "squeezed" by the anamorphic lens. After it was unsqueezed by a complementary anamorphic optical element, the tank operator could see double the horizontal field of view without significant distortion.〔 Gottschalk and Moore bought some of these lenses from C. P. Goerz, a New York optics company, for use in their underwater photography. As widescreen filmmaking became popular, Gottschalk saw an opportunity to provide anamorphic lenses to the film industry—first for projectors, and then for cameras. Nicholson, a friend of Moore, started working as a cameraman on early tests of anamorphic photography.〔Bijl, Adriaan. ("The Importance of Panavision." ) ''The 70mm Newsletter'' no. 67 (in70mm.com).

Film studios sought to lure audiences to theaters with attractions that television could not provide. These included a revival of color films, three-dimensional films, stereophonic sound, and widescreen movies. Cinerama was one of the first widescreen movie processes of the era.〔Hart, Martin. ("A Little Pre-history." ) WidescreenMuseum.com. Retrieved on 2007-01-19.〕 In its initial conception, the cumbersome system required three cameras for shooting and three synchronized projectors to display a picture on one wide, curved screen. Along with the logistical and financial challenges of tripling equipment usage and cost, the process led to distracting vertical lines between the three projected images.〔Pryor, Thomas M. ("Cine-Miracle Joins Big Screen's Big Parade." ) ''New York Times'' 1955-07-13. Retrieved on 2007-01-19.〕 Looking for a high-impact method of widescreen filmmaking that was cheaper, simpler, and less visually distracting, 20th Century Fox acquired the rights to a process it branded CinemaScope: in this system, the film was shot with anamorphic lenses.〔Gray, Peter. ("CinemaScope, A Concise History." ). Retrieved on 2008-07-06〕 The film was then exhibited with a complementary anamorphic lens on the projector that expanded the image, creating a projected aspect ratio (the ratio of the image's width to its height) twice that of the image area on the physical frame of film. By the time the first CinemaScope movie—''The Robe'' (1953)—was announced for production, Gottschalk, Moore and Nicholson had a demo reel of work with their anamorphic underwater system.〔 Gottschalk learned from one of his vendors that Bausch & Lomb, whom Fox had contracted to manufacture CinemaScope lenses, was having difficulty filling the lens orders for theatrical anamorphic projection equipment.〔 He teamed up with William Mann, who provided optical manufacturing capability, and Walter Wallin, an optical physicist who was an acquaintance of Mann's. The anamorphic lens design they selected was prismatic rather than the cylindrical design of the Bausch & Lomb CinemaScope lens.〔 This design meant the anamorphic lens extension factor—how much the image is horizontally unsqueezed—could be manually shifted, useful for projectionists switching between nonanamorphic ("flat" or "spherical") trailers and an anamorphic feature.〔 The result was the anamorphosing system, designed by Wallin, used in the Panatar lens; the patent for the system was filed on August 11, 1954, and awarded five years later.〔Wallin, Walter.
