Its 11-blade rounded diaphragm produces smooth, natural bokeh, while a 0.3 m minimum focus distance and 1:4 magnification ratio enable striking close-ups with dramatic subject separation. Physically, the lens is optimized for professional rigs, featuring a standard 95mm front diameter for matte boxes, an 82mm filter thread, and a robust SF-91 lens support foot included for added stability on rails. Measuring approximately 151–153 mm in length and weighing around 1.2 kg, it balances well on cinema cameras while remaining practical for handheld and stabilizer setups. With dust- and splash-resistant construction, this cine zoom is ready for demanding shooting environments, whether on location or in studio. Offered in Sony E-mount and L-mount, with both feet and metric focus scale options, the Sigma 28–45mm T2 Cine Zoom Lens with AF stands apart by delivering rare autofocus capability in a true cine lens without compromising optical excellence or mechanical precision—making it a compelling investment for professionals who want speed, consistency, and cinematic quality in one versatile tool.

Features:

True Cinema Zoom with Built-In Autofocus

The Sigma 28–45mm T2 Cine Zoom Lens with AF stands apart as one of the very few true cinema lenses to offer integrated autofocus, eliminating the traditional tradeoff between cinematic handling and modern AF performance. Powered by Sigma’s High-Response Linear Actuator (HLA), the autofocus system delivers fast, accurate, and nearly silent focusing designed specifically for video capture. This enables reliable subject tracking, smoother focus transitions, and reduced focus hunting—ideal for solo operators, documentary shooters, gimbal work, live productions, and fast-paced commercial environments where speed and precision matter more than ever.

Constant T2 Aperture for Consistent Exposure and Creative Control

Unlike variable-aperture zooms, this lens maintains a constant T2 transmission across the entire 28–45mm range, ensuring exposure consistency while zooming. This is critical for professional productions where lighting continuity and grading efficiency are non-negotiable. The fast T2 aperture also enables superior low-light performance, cleaner shadows, and greater creative control over depth of field—allowing filmmakers to shape mood, isolate subjects, and maintain cinematic visual integrity without constant lighting or camera adjustments.

Full-Frame Coverage Optimized for Modern Cinema Cameras

Designed to cover full-frame sensors, the Sigma 28–45mm T2 Cine Zoom supports the latest high-resolution cinema cameras without vignetting or edge degradation. With a horizontal angle of view ranging from 65.5° to 43.6°, it delivers versatile framing options suited for establishing shots, interviews, narrative scenes, and dynamic movement shots. This future-ready full-frame coverage protects your investment as camera technology continues to evolve.

Cinema-Grade Mechanical Design with Precision Control

Every mechanical aspect of this lens is engineered to meet professional cinema standards. It features industry-standard 0.8 MOD gears on the focus, zoom, and iris rings, ensuring seamless compatibility with follow-focus systems and motorized controls. The lens offers a 200° focus rotation, 60° zoom throw, and 57° iris rotation, allowing precise, repeatable adjustments essential for narrative work, multi-take scenes, and complex focus pulls. The fully de-clicked aperture ring enables smooth exposure transitions without visible stepping.

Optical Performance Based on Sigma Art-Series Excellence

Built on the proven optical design of Sigma’s acclaimed 28–45mm F1.8 DG DN | Art lens, this cine version delivers exceptional sharpness, contrast, and color accuracy across the frame. The lens produces clean, detailed images with controlled flare and ghosting, even in challenging lighting. This optical consistency simplifies color matching, reduces post-production correction, and ensures footage holds up across multiple camera systems and shooting conditions.

Smooth, Natural Bokeh with an 11-Blade Iris

The 11-blade rounded diaphragm creates smooth, organic bokeh that enhances subject separation and cinematic depth. Highlights remain soft and natural, helping footage feel polished and emotionally engaging rather than clinical. This is especially valuable for interviews, narrative close-ups, and commercial work where visual tone plays a critical role in storytelling.

Close-Focus Capability for Versatile Shot Design

With a minimum focus distance of just 0.3 meters and a 1:4 magnification ratio, the lens enables striking close-ups without the need to swap lenses or add diopters. This flexibility allows filmmakers to capture detail shots, product visuals, and expressive framing while maintaining consistent optical character throughout the scene.

Professional Rig Compatibility and On-Set Practicality

The lens features a standard 95mm front diameter, making it fully compatible with professional matte boxes, filters, and cine accessories. An 82mm filter thread offers additional flexibility for lightweight setups. The included SF-91 lens support foot improves stability on rails and reduces strain on the camera mount—essential for long shooting days and heavier rig configurations.

Balanced Build for Handheld, Gimbal, and Studio Use

Weighing approximately 1.2 kg and measuring around 151–153 mm in length, the Sigma 28–45mm T2 Cine Zoom is carefully balanced for a wide range of shooting styles. It performs equally well on shoulder rigs, tripods, sliders, and motorized gimbals, making it a highly adaptable tool for modern hybrid productions.

Dust- and Splash-Resistant Construction for Real-World Shoots

Built for professional use beyond controlled studio environments, the lens features dust- and splash-resistant construction. This added durability ensures reliable performance during outdoor shoots, travel productions, and unpredictable weather conditions—helping crews stay productive when conditions are less than ideal.

Multiple Mount Options and Professional Marking Choices

Available in Sony E-mount and L-mount, the lens supports a wide range of cinema and mirrorless camera systems. Sigma also offers both feet and metric focus scale versions, allowing cinematographers to match their preferred measurement system for accurate, intuitive focus pulling on set.
