Lens designed for still photography, adapted for use on film cameras. Often more affordable than cine lenses but lacks gear rings for follow focus.
Technical Details
Stills lenses use mechanical aperture rings with click stops in 1/3 stops (f/1.4, f/1.6, f/1.8, f/2.0), while cinema lenses use stepless apertures. The focus ring typically rotates 90-180°, significantly less than the 270-330° of cinema lenses. Typical focal lengths range from 14mm ultra-wide-angle to 600mm super-telephoto. The minimum focus distance for 50mm lenses is usually between 35-45cm, while macro lenses can achieve up to 1:1 magnification.
Autofocus systems use ultrasonic or stepping motors and achieve focusing speeds of 0.1-0.3 seconds. Optical image stabilization compensates for shake by 3-5 stops through movable lens groups or sensor-shift mechanisms.
History & Development
The first photographic lens was developed by Joseph Nicéphore Niépce in 1826 for his heliography. Carl Zeiss introduced the Planar design in 1896, which remains a benchmark for high-quality standard lenses today. Leica revolutionized 35mm photography in 1925 with the Elmar 50mm f/3.5.
Autofocus became established from 1985 with the Minolta Alpha system. Canon introduced the ultrasonic motor (USM) in 1987, followed in 2016 by the first full-frame compatible 11-24mm f/4 zoom. Current developments focus on mirrorless systems with shorter flange distances: Canon RF (20mm), Sony E (18mm), Nikon Z (16mm).
Practical Use in Film
Stills lenses are used in budget-oriented productions and for special effects. David Fincher used Canon EF 50mm f/1.2 lenses on RED cameras for "Gone Girl" (2014) to achieve a characteristic look. The Netflix series "Stranger Things" combines Zeiss Standard Speeds with vintage Canon FD lenses for nostalgic effects.
Unit photographers use identical lenses to the film crew to ensure a consistent visual language in publicity materials. Discreet autofocus enables unobtrusive documentary shooting. Problems include focus breathing effects during focus pulls and the click-stopped aperture during exposure changes while shooting.
Comparison & Alternatives
Cinema lenses offer stepless apertures, precise focus markings, uniform front diameters (usually 95mm or 114mm), and minimal focus breathing. Stills lenses score points for autofocus, image stabilization, lower weight, and significantly lower acquisition costs: a Canon EF 50mm f/1.4 costs around 400 Euros, comparable Zeiss CP.3 50mm T2.1 lenses around 4,000 Euros.
Modern hybrid lenses like Sigma Cine combine photographic versatility with cinematic precision – but without autofocus. For streaming productions delivered in 2K, the optical quality of premium stills lenses is entirely sufficient.
