Cinema lens featuring gear rings for follow-focus, continuous iris control, and minimal focus breathing. Optimized for professional film production.
Technical Details
Cine lenses consistently use T-stops (Transmission Stop) instead of F-stops, which measure actual light transmission. Typical wide apertures range from T1.3 to T2.8. The focus ring has a throw of at least 270°, with premium lenses reaching up to 330°. Standard mounts are PL-Mount (Positive Lock) with a 52mm diameter or LPL-Mount with 62mm. The front thread is usually 114mm or 136mm for matte box systems. Cine lenses feature a constant front lens position (Non-Breathing) and uniform 110mm housing diameters for uncomplicated lens changes.
History & Development
The first cine lenses emerged in the 1920s when Cooke developed optics specifically optimized for film cameras with the Speed Panchro series. In 1971, ARRI introduced the PL-Mount as an industry standard. Zeiss revolutionized low-light cinematography in 1975 with the Super Speed T1.3 lenses. In the 1990s, zoom lenses like the Angenieux Optimo 24-290mm became established. Since 2018, the LPL-Mount has been gaining traction for large format sensors, while modern Master Prime and Signature Prime series cover focal lengths from 12mm to 200mm.
Practical Use in Film
Roger Deakins used Zeiss Master Primes for "1917" (2019) to achieve continuous camera movements with precise focus. The Cooke S7/i series was used on "Dune" (2021), producing the characteristic "Cooke Look" with soft bokeh. Anamorphic lenses like the ARRI Master Anamorphic create the 2.39:1 aspect ratio with typical lens flares. Lens changes are facilitated by standardized Lens Data Systems (LDS), which automatically transfer metadata to the camera. Follow focus systems like the ARRI cforce mini enable precise focus pulls during shooting.
Comparison & Alternatives
Cine lenses differ from still photography lenses through mechanical precision and continuous adjustment without click stops. While still lenses are optimized for fast autofocus, cine lenses offer manual control with repeatable settings. Canon CN-E and Sony CineAlta represent entry-level options starting from €3,000, while ARRI Signature Primes can cost up to €45,000. Modern alternatives include rehoused still lenses from Duclos Lenses or Sigma Cine versions of existing Art lenses with added gear rings and T-stop calibration.
