The Angenieux Optimo Ultra Compact 37-102mm Zoom Lens Full Pack is a high-end, highly adaptable cinematic zoom lens tailored for elite multi-format cinematography. Leveraging Angenieux’s patented Interchangeable Rear Optics (IRO) technology, this “Full Pack” includes two distinct, hot-swappable rear optical blocks—the Full-Frame/VistaVision (FF/VV) and the Ultra 35/Open Gate (U35) modules. This dual-nature configuration allows DPs to switch the lens effortlessly between large-format digital sensors and Super35 sensor setups while maintaining optimized optical geometry.
