Anamorphic lens with integrated compensation mechanism coupling focus and anamorphic distortion adjustment. Compresses 2:1 horizontally, eliminating synchronization errors inherent in dual-focus systems.

Technical Details

Single-focus anamorphics operate with an integrated compensation mechanism that automates the mechanical coupling between focus and anamorphic settings. Typical focal lengths range from 25mm to 200mm, with apertures usually between T2.8 and T4. Horizontal compression is achieved via cylindrical lens elements with a factor of 2:1, while the vertical image plane remains unchanged. Modern single-focus systems achieve resolutions exceeding 6K with minimal chromatic aberration.

History & Development

Panavision developed the first single-focus anamorphics in 1958 as a response to the cumbersome handling of Henri Chrétien's original Hypergonar systems. In 1962, Todd-AO introduced the first fully integrated single-focus lenses with the 35 series. In 1999, Zeiss revolutionized the market with its Master Anamorphic lenses, which for the first time offered a consistent T1.9 aperture with single-focus functionality. Starting in 2016, Atlas Lens Co. established a new generation of affordable single-focus anamorphics for independent productions with its Orion lenses.

Practical Use in Film

Roger Deakins used Arri Master Anamorphic 40mm and 75mm single-focus lenses for "Blade Runner 2049" (2017) to achieve characteristic horizontal lens flares while maintaining precise focus. "Mad Max: Fury Road" (2015) consistently used Panavision G-Series single-focus lenses for rapid focus pulls during chase sequences. Single-focus systems reduce focusing time by approximately 40% compared to dual-focus setups and eliminate the risk of synchronization errors between the two focus planes.

Comparison & Alternatives

Dual-focus anamorphics require separate adjustment of the spherical base optics and the anamorphic attachment, but often offer higher optical quality at lower costs. Digital anamorphic simulation achieves the 2.39:1 look without optical distortion but sacrifices characteristic bokeh effects and lens flares. ARRI Signature Primes with a 2.39:1 sensor crop offer a similar visual impact with spherical optics, while Cooke Anamorphic/i lenses are considered a modern single-focus alternative to Zeiss Master Anamorphics.

Perspectives

Cinematographer

Ich schätze Single-Focus-Anamorphote für schnelle Handkamera-Arbeiten, da ich mich auf einen Fokusring konzentrieren kann, während der charakteristische anamorphe Look mit den ovalen Bokehs und horizontalen Flares erhalten bleibt. Bei schwierigen Lichtverhältnissen spare ich wertvolle Sekunden, weil ich nicht zwischen zwei Fokusebenen jonglieren muss – besonders bei spontanen Schwenks oder wenn Schauspieler ihre Positionen ändern.

Director

Single-Focus-Anamorphote geben mir die Flexibilität, spontane Kamerabewegungen und schnelle Schnittfolgen zu realisieren, ohne dass die Crew Zeit für komplexe Fokus-Setups benötigt. Das 2,39:1-Format verstärkt die epische Wirkung von Landschaftsaufnahmen und schafft gleichzeitig Intimität in Nahaufnahmen durch die charakteristische Unschärfe-Charakteristik – ich kann emotionale Beats präziser setzen, weil der Fokus-Pull schneller erfolgt.

Producer

Single-Focus-Systeme reduzieren meine Drehtage um 10-15%, da komplexe Fokus-Setups entfallen und weniger Takes wegen Fokussierfehlern wiederholt werden müssen. Die Mietkosten liegen bei etwa 800-1.200 Euro pro Objektiv und Woche, aber die Zeitersparnis am Set kompensiert die höheren Kosten gegenüber Dual-Focus-Alternativen – besonders bei Termindruck oder wenn die Crew weniger anamorphe Erfahrung hat.
