Features:

Full-Frame Coverage with a True 43.3mm Image Circle

The Sigma 28mm T1.5 FF High-Speed Prime is engineered to fully cover full-frame sensors with a generous 43.3mm image circle, eliminating vignetting and edge falloff even on large-format cinema cameras. This gives filmmakers the freedom to shoot full-frame or crop into Super 35 without compromising image quality, making the lens highly versatile for multi-camera productions and future sensor upgrades.

Ultra-Fast T1.5 Aperture for Low-Light and Cinematic Depth

With a blazing-fast T1.5 aperture, this lens excels in low-light environments where maintaining image integrity is critical. It allows you to shoot with less artificial lighting, preserve natural ambience, and create a shallow depth of field that delivers strong subject separation. The result is a cinematic look that feels intentional, controlled, and emotionally engaging.

6K–8K Ready Optical Performance

Designed to meet the demands of modern and future cinema cameras, the Sigma 28mm T1.5 FF High-Speed Prime resolves exceptional detail suitable for 6K and 8K workflows. Its advanced optical formula maintains sharpness across the frame while controlling distortion and chromatic aberration, ensuring footage remains clean, detailed, and production-ready for high-resolution delivery and heavy post-processing.

Advanced Optical Design with FLD, SLD, and Aspherical Elements

The lens features a sophisticated construction of 17 elements in 12 groups, incorporating FLD and SLD glass along with precision-molded aspherical elements. This design minimizes color fringing, reduces distortion, and maintains high contrast from center to edge. The benefit is consistent image quality that holds up under demanding lighting conditions and complex scenes.

Consistent Color Rendering Across the Sigma FF Cine Line

Color consistency is critical in professional production, and this lens is engineered to match the color science of Sigma’s FF High-Speed Prime lineup. This ensures seamless intercutting between focal lengths without time-consuming color correction, helping productions move faster while maintaining a cohesive visual style.

Rounded 9-Blade Iris for Smooth, Natural Bokeh

The 9-blade rounded diaphragm produces soft, pleasing bokeh and natural highlight roll-off, even when shooting wide open. This enhances the cinematic character of out-of-focus areas, adding depth and emotional nuance to your shots rather than harsh or distracting background blur.

Precision Manual Focus with 180-Degree Rotation

A long 180-degree focus throw provides filmmakers with precise control over focus pulls, essential for narrative filmmaking and controlled camera movements. This extended rotation allows for smooth, repeatable focus transitions, giving focus pullers the accuracy they need in high-pressure shooting environments.

Clickless Manual Iris with Linear Control

The clickless aperture ring offers smooth, silent exposure adjustments during takes, making it ideal for live-action scenes and dynamic lighting conditions. Linear iris movement ensures predictable exposure changes, giving operators full creative control without introducing unwanted jumps or noise.

Industry-Standard 0.8 MOD Cine Gears

Built to professional cine standards, the focus and iris rings feature 0.8 MOD gearing compatible with follow focus systems, motors, and wireless controls. Gear placement is standardized across Sigma’s FF cine primes, allowing fast lens changes without reconfiguring your rig—saving valuable time on set.

Robust All-Metal, Dust- and Splash-Resistant Construction

This lens is designed for real production environments, not studio-only use. Its all-metal housing, engraved markings, and dust- and splash-resistant sealing ensure long-term reliability in challenging conditions, whether you’re shooting on location, outdoors, or in fast-paced production schedules.

Luminous Markings for Low-Light Operation

High-visibility focus and aperture markings—available in standard or fully luminous configurations—make the lens easy to operate in dark environments. This improves efficiency during night shoots or controlled lighting setups where visibility is limited.

Close Minimum Focus Distance for Creative Flexibility

With a minimum focusing distance of just 0.3 meters (1 foot), the Sigma 28mm T1.5 allows for dramatic close-ups while maintaining a wide perspective. This opens creative possibilities for storytelling without needing to swap lenses or compromise composition.

Professional Cine Form Factor with 95mm Front Diameter

A 95mm front diameter ensures compatibility with industry-standard matte boxes and accessories, while the 82mm filter thread provides flexibility for screw-on filters. The balanced physical design integrates smoothly into professional camera rigs without unnecessary bulk.

Multiple Mount Options with Cooke /i Metadata Support

Available in Canon EF, Sony E, and PL mounts, the lens adapts easily to a wide range of cinema cameras. PL versions support Cooke /i Technology, enabling lens metadata capture for streamlined post-production, VFX, and virtual production workflows.
