Features:

Constant T2 Aperture Across the Entire Zoom Range

The Sigma 18-35mm T2 maintains a true constant T2 transmission from 18mm to 35mm, eliminating exposure shifts while zooming and giving cinematographers complete creative control. This is critical for professional productions where lighting consistency matters, especially during live zooms, gimbal work, or documentary shooting. The fast T2 aperture also enables shooting in challenging low-light environments without excessive noise, preserving image integrity and saving time in post.

Optimized for Super 35 Sensors With 6K–8K Resolution Support

Designed specifically for Super 35 image circles, this lens delivers edge-to-edge sharpness and contrast that holds up under modern 6K and 8K cinema cameras. Unlike lenses that soften at higher resolutions, the Sigma 18-35mm T2 resolves fine detail consistently, making it a long-term investment that remains relevant as camera technology advances.

Advanced Optical Design for Clean, Cinematic Image Quality

With 17 elements in 12 groups, including low-dispersion and aspherical elements, the optical formula minimizes chromatic aberration, distortion, and focus breathing. The result is footage with strong micro-contrast, accurate color reproduction, and a natural cinematic look that reduces the need for heavy correction in post-production.

Cine-Standard Manual Control for Precision Operation

Built from the ground up for cinema workflows, the lens features fully manual focus, zoom, and iris rings with long rotation angles—180° focus throw, 160° zoom throw, and 60° iris throw. These extended throws provide smooth, repeatable adjustments that professional focus pullers rely on, especially during complex shots or narrative filmmaking.

Clickless 9-Blade Iris for Smooth Exposure and Organic Bokeh

The clickless T2–T16 iris allows seamless exposure changes during recording, while the 9-blade rounded diaphragm produces soft, natural bokeh. This combination enhances subject separation and gives footage a refined, filmic aesthetic that stands out in commercial, cinematic, and branded productions.

Cine-Standard Gear Placement for Faster Lens Changes

All control rings use 0.8 MOD gears positioned consistently with other Sigma Cine lenses, allowing for quick lens swaps without reconfiguring follow-focus systems. This standardization saves valuable time on set, improves workflow efficiency, and reduces setup errors during fast-paced shoots.

Internal Focus Design for Stable Balance and Reduced Breathing

The internal focus mechanism keeps the lens length constant during focus pulls, improving balance on gimbals, drones, and shoulder rigs. It also minimizes focus breathing, ensuring that framing remains stable when shifting focus—an essential characteristic for professional cinematography.

Close Focusing Capability for Creative Flexibility

With a minimum focus distance of just 0.28 meters (11 inches) and a 1:4.3 maximum magnification, the Sigma 18-35mm T2 enables dramatic close-ups without switching lenses. This allows filmmakers to move quickly between wide establishing shots and intimate detail shots, increasing storytelling versatility while reducing downtime.

Professional All-Metal Construction Built for Production Environments

The lens features a fully metal housing with dust- and splash-resistant sealing, designed to withstand demanding shooting conditions. Whether on location or in studio environments, this durability ensures consistent performance and reliability over long production schedules.

Industry-Standard Front Diameter and Filter Compatibility

With a 95mm front diameter and 82mm filter thread, the lens integrates effortlessly with matte boxes, filters, and cine accessories commonly used on professional sets. This compatibility reduces the need for additional adapters or gear changes, streamlining production workflows.

Multi-Mount Compatibility for Broad Camera Support

Available in PL, Canon EF, and Sony E mounts, the Sigma 18-35mm T2 fits seamlessly into a wide range of cinema and mirrorless camera systems. This flexibility makes it an excellent choice for owner-operators, rental houses, and production teams working across multiple platforms.

Included Support Foot for Rig Stability and Mount Protection

The included removable lens support foot helps distribute weight evenly across the rig, reducing stress on the camera mount during handheld, tripod, or rigged setups. This added stability protects your equipment and improves long-term reliability during heavy production use.

Exceptional Value Compared to High-End Cinema Zooms

The Sigma 18-35mm T2 delivers performance comparable to significantly more expensive cinema zoom lenses while remaining far more accessible.
