Introduction to SIGMA's AF Cine Line Lenses
At Cine Gear 2026, SIGMA showcased its latest advancements in the form of the AF Cine Line 28-45mm T2 and 28-105mm T3 lenses. Released in late 2025 and early 2026 respectively, these lenses are designed to bridge the gap between traditional cinema optics and the growing demands of modern hybrid production workflows. Built upon the optical heritage of SIGMAs Art-series still lenses, these tools are crafted for professional motion work while incorporating cutting-edge features tailored for today's fast-paced production environments.
Key Features of the AF Cine Line
Both lenses in the AF Cine Line are equipped with industry-standard 0.8 MOD gearing, ensuring compatibility with professional focus systems. They feature clickless aperture rings for seamless exposure adjustments, a necessity for cinematic applications. Additionally, these lenses boast limited-rotation focus throws, which provide precise control for manual focusing. Supporting both Sony E-mount and L-Mount systems, they cater to a wide range of professional setups and ensure maximum versatility for filmmakers.
Autofocus Integration for Modern Production Needs
A standout feature of the AF Cine Line lenses is their continuous autofocus support, which is rare in traditional cinema zooms. When paired with compatible camera systems, these lenses offer subject tracking capabilities, making them ideal for scenarios requiring speed and mobility. This feature proves invaluable for gimbal work, solo operators, and documentary filmmaking, where conventional focus-pulling setups may not be practical or efficient.
Performance and Optical Quality
Engineered for high performance, the AF Cine Line lenses deliver consistent image rendering, maintaining high resolution and controlling flare and ghosting across the zoom range. The design also minimizes focus breathing, a critical factor in both narrative cinematography and commercial shoots. The 28-45mm T2 FF lens, featuring a constant T2 aperture, excels in low-light conditions and achieves a shallow depth of field, while the 28-105mm T3 FF lens offers a broader focal range for diverse production needs.
Physical Design and Practicality
Despite their full-frame cine zoom specifications, the AF Cine Line lenses are relatively compact and lightweight, making them easier to handle on set. Their matching gear positions and consistent design enable efficient lens changes, especially in high-pressure environments. This thoughtful design approach ensures that the lenses integrate seamlessly into professional workflows, supporting the operational demands of both run-and-gun productions and carefully staged setups.
