Description — Zeiss 21-100mm T2.9-3.9
The ZEISS LWZ.3 is a professional cine zoom lens covering a 21mm to 100mm focal length range, classified as a Wide Angle to Telephoto zoom and built for Super 35 format cinema cameras. It uses the PL Mount, the standard mount across professional digital cinema platforms, and features a T2.9 to T3.9 aperture range — opening at T2.9 at the wide end for practical use in controlled lighting environments. Focus is manual, in keeping with cinema production standards where follow focus systems are the norm.
The lens features a 95mm filter thread for use with matte boxes and optical filters common on professional sets. Weighing 2000g, the LWZ.3 is a substantial piece of glass that demands proper camera support. There is no image stabilization, so productions should plan accordingly with stabilized rigs or platforms.
This is a Cine-type zoom lens designed for productions that need a wide focal range in a single cinema-spec optic.
