Cinema zoom with constant aperture across focal range. Focus breathing negligible, built for daily set use. Fewer lens swaps, more shooting time.
Technical Details
The Optimo series encompasses various focal length ranges: the Optimo 15-40mm T2.6, 17-80mm T2.2, 24-290mm T2.8, 28-76mm T2.6, and the extreme 28-340mm T3.2. All lenses feature constant T-stops (Transmission aperture values), 300° focus ring rotation for precise focus pulling, and standardized gear rings (0.8 module) for follow focus systems. The construction is based on aspherical elements and ED (Extra-low Dispersion) elements to minimize chromatic aberrations. Weight varies between 3.2 kg (15-40mm) and 8.5 kg (28-340mm).
History & Development
Angenieux introduced the first Optimo generation in 2001 with the 17-80mm, building on 60 years of experience in zoom development since the first Varifocal lenses in 1956. In 2004, the revolutionary 24-290mm with a 12:1 zoom ratio followed, which for the first time combined the focal length ranges of a complete lens set in a single lens. In 2013, the Optimo Style series expanded the portfolio with lighter, more compact variants. The latest generation, Optimo Prime (since 2018), combines zoom flexibility with prime lens quality.
Practical Application in Film
Cinematographers use Optimo lenses for continuous zoom moves without changing lenses, for example in "Gravity" (2013) for seamless perspective shifts in space or "1917" (2019) for the famous long takes. The extreme 24-290mm allows for shots from wide-angle to super-telephoto without interruption, significantly reduces setup times, and minimizes dust-busting in post-production. The constant aperture prevents exposure jumps during zooming, and the precise mechanics enable repeatable camera movements for VFX shots.
Comparison & Alternatives
In contrast to prime lens sets, Optimos offer extreme flexibility with slightly reduced optical sharpness. Modern alternatives like Canon CN20x50 or Fujinon Premista achieve similar zoom ratios, but usually at a higher weight. Zeiss Lightweight Zooms are more compact but cover smaller focal length ranges. For maximum image quality, Master Prime sets remain superior; for documentary work or tight shooting schedules, Optimos dominate due to their versatility.
