Zeiss CP.2 21mm T2.9 Compact Prime Distagon T* Manual Cine Lens for Sony E-Mount, Black with Imperial Focus Scale Review

The Zeiss CP.2 21mm T2.9 is a manual cinema prime designed for Sony E-mount cameras, part of Zeiss's well-regarded Compact Prime line. Built around the classic Distagon optical formula with T* anti-reflective coating, this lens delivers the sharp, neutral rendering and consistent color that cinema shooters expect from Zeiss glass. The 21mm focal length offers a moderately wide field of view useful for environmental shots, interiors, and establishing scenes without veering into ultra-wide territory.

At T2.9, it's not the fastest cine prime available, but it strikes a practical balance between light gathering and size. The manual focus ring with imperial markings is geared for follow focus systems, and the consistent front diameter across the CP.2 range simplifies rigging and lens swaps on set. The used "EX+" grade from KEH suggests a lens in excellent cosmetic and functional condition, making it a cost-effective entry into professional cine glass for independent filmmakers or owner-operators building out a lens set.
