Description — Sigma 18-35mm T2
The Sigma 18-35mm T2 High-Speed Zoom Lens is built for professional cinema and video production, covering a 18mm to 35mm focal length range at a constant T2 aperture. The consistent T2 stop across the entire zoom range is a key operational advantage — exposure stays locked whether you're shooting at 18mm or 35mm, removing the need for iris adjustments mid-zoom. Designed specifically for the Super 35 format, it aligns with the sensor size found in many professional cinema cameras.
The lens features manual focus only, in keeping with cinema production standards where focus pullers rely on precise, measurable focus distances. Mount options include Canon EF, Sony E, and PL Mount, offering meaningful cross-platform compatibility. The 82mm front filter thread works with standard filter systems and matte boxes.
Weighing 1400g, this lens is built with the solidity expected in demanding production environments. There is no image stabilization, so use on a supported rig or stabilized platform is recommended.
