Professional cinema zoom lens with 45-120mm focal length covering medium to telephoto range for narrative and documentary work.
Technical Details
The 45-120mm features a 15-blade iris for natural bokeh and covers a 31.5mm image circle. The minimum focus distance is 85cm, and the front filter diameter is 114mm. The integrated servo motor allows for precise zoom movements with variable speed via the /i Technology interface. The lens uses a PL mount and offers Lens Data System (LDS) for transmitting metadata to the camera. The optical construction comprises 20 lens elements in 14 groups, including ED (Extra-low Dispersion) glass to reduce chromatic aberrations.
History & Development
Angenieux first introduced the 45-120mm in 2014 as part of the EZ series to meet the growing demand for compact, servo-driven zooms for digital film productions. The development was based on experience with the larger Optimo lenses but was specifically optimized for smaller camera setups and documentary workflows. In 2016, a revised version followed with improved servo mechanics and optimized color matching for newer camera sensors.
Practical Use in Film
The 45-120mm is particularly suitable for run-and-gun productions and documentaries where rapid focal length changes are required without lens changes. Its compact size makes it a top choice for Steadicam and gimbal work. In the series "The Crown," the camera team used the lens for intimate portrait shots, as the T2.8 aperture provides sufficient latitude even in available light. The servo zoom allows for smooth push-ins during takes without requiring a focus puller to operate the lens.
Comparison & Alternatives
Compared to the heavier Angenieux Optimo 45-120 (4.2 kg), the EZ version offers significantly better handling with minimal optical compromises. Canon's CN-E 30-105mm covers a similar focal length range but lacks an integrated servo motor. Fujinon's MK50-135mm offers comparable aperture but starts at a focal length of 50mm. For productions with larger budgets and the highest image quality demands, the Optimo 45-120 remains the benchmark, while the EZ 45-120 represents the optimal compromise between image quality and mobility.
