Constant T2.4 Aperture. The 20-50’s fast, constant T2.4 aperture makes for great low-light performance and subject/background separation throughout the zoom range, while the 11-blade diaphragm accommodates minute exposure adjustments with pleasing bokeh and out-of-focus highlights.

Cine Lens Build. The CN-E 20-50mm is enclosed in a traditional video-lens housing. Its focus, zoom, and iris rings have industry-standard gears and 0.8mm pitch, so you can use most standard follow focuses and other third-party accessories. This lens offers a focus-rotation angle of approximately 300 degrees, allowing for long focus throws. Its two-foot minimum focusing distance makes it possible to shoot in tight spaces.

Metadata Support. This lens supports Cooke’s /i metadata protocols to communicate with the camera, recording optical characteristics and lens settings to every frame to make post-production easier. This is especially useful when you’re adding effects in post. This is especially useful when you’re adding effects in post.
