Large Iscorama anamorphic front attachment lens with 54mm diameter, designed for fast telephoto lenses and professional cinema cameras.
Technical Details
The Iscorama 54 works with two cylindrical lens elements that compress the image horizontally by a factor of 2, while the vertical dimension remains unchanged. The front attachment lens has a fixed focal length and transfers focusing to the main lens behind it. The minimum focusing distance starts at 1.5 meters, which is sufficient for portrait shots. The optical design produces characteristic horizontal lens flares and slight vignetting in the image corners. The weight is approximately 800 grams, and the length is around 120mm. Various adapters allow its use on modern DSLR and film cameras with different lens mounts.
History & Development
ISCO Optic developed the Iscorama 54 between 1963 and 1965 as a cost-effective alternative to the expensive anamorphic cinema lenses from Panavision and Zeiss. Originally designed for 16mm projectors, it quickly found use in low-budget film production. Production ceased in the 1970s, making surviving examples highly sought-after collector's items today. From 2010 onwards, the Iscorama 54 experienced a renaissance through digital filmmakers and YouTubers, as it offered the typical anamorphic look much more affordably than new developments from RED or Cooke.
Practical Use in Film
The Iscorama 54 was primarily used in European B-movies of the 1970s, including several Italo-Westerns and French crime films. Modern filmmakers like Sean Baker have used it for experiments with the Cinemascope format in digital productions. The typical workflow requires shooting in 4:3 aspect ratio with subsequent horizontal stretching by 100% in post-production. The advantage is the characteristic analog look with soft lens flares and slight distortion. Disadvantages include the limited close-focus capability, a light loss of approximately 1-1.5 stops, and the complex focusing via two separate systems.
Comparison & Alternatives
Unlike modern anamorphic lenses such as the Cooke Anamorphic/i or ARRI Master Anamorphic, the Iscorama 54 works as a front attachment and therefore always requires an additional spherical lens. Contemporary alternatives included the Kowa Anamorphic or Sankor front attachments, which are, however, less commonly available. Today, digital anamorphic emulations in post-production often replace the analog look but do not achieve the optical characteristics of real glass elements. For budgets under 5,000 Euros, the Iscorama 54 remains one of the most authentic ways to utilize genuine anamorphic optics.
