Sigma 28-45mm T2 Cine Zoom

Fast Mid-Range Cinematic Zoom

The Sigma 28-45mm T2 Cine Zoom is a fast, mid-range Super 35 cinema zoom designed for productions requiring high optical performance and maximum flexibility in a compact form factor. It covers the most frequently used framing range in narrative filmmaking, making it a core tool for handheld, studio, and gimbal-based workflows.

With its constant T2 aperture, the lens delivers strong low-light performance and consistent exposure across the zoom range. This allows cinematographers to work confidently in changing lighting environments without adjustments during zoom transitions.

The optical design prioritizes sharpness, contrast, and natural color reproduction while minimizing distortion and chromatic aberration. Focus breathing is carefully controlled to maintain cinematic consistency during focus pulls.

Mechanically, the lens features full cine-standard construction with 0.8 MOD gears, smooth manual focus rotation, and durable all-metal housing. It integrates seamlessly into professional production environments and supports both manual and motorized lens control systems.

As part of Sigma’s cine lineup, the 28-45mm T2 maintains consistent color rendering and mechanical layout across the system, ensuring fast and efficient lens changes in multi-lens workflows.

Its combination of speed, compactness, and optical quality makes it particularly suitable for high-end commercial, narrative, and broadcast production environments.
