Description — Zeiss 25mm T2.1
The ZEISS CP.3 XD 25mm T2.1 is a prime cinema lens built for full-frame coverage and mounted in the industry-standard PL mount configuration. Operating in the wide-angle focal length range at a fixed 25mm, it offers a maximum aperture of T2.1, providing reliable performance in a variety of lighting conditions. The lens is entirely manual focus, with no autofocus or image stabilization — a deliberate design choice that aligns with professional cinema workflows where focus pullers and measured technique are standard practice.
Weighing 820g, it is appropriately sized for a full-frame cinema prime. The 95mm filter thread is a shared specification across the CP.3 family, making it straightforward to use consistent front-end accessories without adapters or size changes between lenses. Classified under the Cinema / Video camera system and typed as Cine, this lens is built specifically for production use, not adapted from a still photography design.
It is a focused, well-specified wide-angle prime for cinematographers working with PL mount cinema cameras.
