Canon CN-E 30-105mm T2.8 L S Cine Zoom Lens for EF-Mount, DEMO Review

The Canon CN-E 30-105mm T2.8 L S is a professional cinema zoom lens built for EF-mount cameras, offering a versatile focal range and constant T2.8 aperture for consistent exposure and depth of field throughout the zoom range. It sits squarely in Canon's Cinema EOS lineup, designed for narrative filmmaking, commercial production, and high-end video work where precise optics, minimal breathing, and robust mechanical build are essential. The lens features cinema-standard gearing for focus, iris, and zoom, making it compatible with follow-focus systems and matte boxes common on professional sets.

This particular unit is a demo model in like-new condition, sold through KEH. As a used item, it provides an opportunity to access Canon's premium cine glass at a lower price point than new retail. The 30-105mm range is well-suited for Super 35 sensors, covering wide establishing shots through medium telephoto, and the constant T2.8 aperture ensures it performs well in a variety of lighting conditions without sacrificing speed.
