Kinoptik lens series with apochromatic correction — reduces chromatic aberrations for precise color reproduction.

Technical Details

The Kinoptik Apochromats utilize fluorite glass elements in combination with special lanthanum glasses to compensate for the dispersion of different wavelengths. Available focal lengths included 25mm, 50mm, 75mm, and 100mm, all with a maximum aperture of T/2.8. The lenses achieve a resolution of 120 Lp/mm in the center and 90 Lp/mm at the image edge at T/4 aperture. The optical design is based on a modified Tessar construction with 6-8 elements in 4-5 groups, with the fluorite element positioned as the second or third element. The focus mechanism operates with an accuracy of ±0.02mm across the entire focus range.

History & Development

Pierre Angénieux developed the first Kinoptik Apochromats in 1952 for the French military, before they were first used in film production in 1955. The breakthrough came in 1958 with François Truffaut's "The 400 Blows," where cinematographer Raoul Coutard used the 50mm Apochromat for extreme close-ups. Between 1960-1970, only about 2,000 units were produced, as the hand-ground fluorite elements were extremely complex to manufacture. In 1975, Kinoptik ceased production as Zeiss and Cooke took over the market with industrially manufactured alternatives.

Practical Use in Film

Kinoptik Apochromats shaped the visual style of the Nouvelle Vague through their neutral color rendition and extreme sharpness. Jean-Luc Godard used the 25mm for the handheld sequences in "Breathless" (1960), while Nestor Almendros used the 75mm for the candlelight scenes in "Days of Heaven" (1978). The lenses require precise exposure, as their high resolution ruthlessly reveals any flaws. With color films, they eliminate the chromatic breathing typical of other lenses during focus shifts. Modern colorists appreciate the neutral skin tones that are usable directly without correction.

Comparison & Alternatives

Compared to contemporary Cooke Speed Panchros, Kinoptik Apochromats offer 40% higher resolution but less "organic" bokeh characteristics. Zeiss Super Speeds achieve similar sharpness values but exhibit stronger color fringing in backlight. Modern alternatives like Zeiss Master Primes or Cooke S7/i surpass the Kinoptiks in speed and mechanical precision but do not match their specific color correction. Vintage Kinoptiks today cost between 8,000-15,000 Euros per lens and are mainly rented for period pieces or deliberately neutral color grading. Canon K35 or Lomo Anamorphics offer a similar vintage character at lower costs.
