Sigma AF Cine Line 28-105mm T3 FF Zoom

Versatile Full Frame Cinema Zoom

The AF Cine Line 28-105mm T3 FF is a versatile full-frame cinema zoom lens designed for productions that require broad focal length coverage, reliable autofocus performance, and professional cinema handling within a single lens system. Developed for modern filmmaking workflows, the lens supports applications ranging from narrative production and documentaries to live events, commercial content, interviews, and fast-moving production environments.

The wide zoom range from 28mm to 105mm allows cinematographers and operators to cover a large variety of framing situations without frequent lens changes. Wide-angle shots, medium perspectives, close-up compositions, and compressed telephoto framings can all be captured within one compact cinema zoom system, improving efficiency during production.

The constant T3 aperture maintains stable exposure performance throughout the entire zoom range while still allowing cinematic background separation and reliable low-light usability. The optical system is optimized for high-resolution cinema capture and delivers balanced sharpness, natural contrast behavior, and smooth out-of-focus rendering suitable for professional motion picture production.

The autofocus functionality is specifically beneficial for productions with dynamic movement, unpredictable action, or limited crew sizes. Subject tracking and responsive focus adjustment help simplify operation during handheld shooting, gimbal movement, event coverage, documentary production, and mobile cinema workflows. The lens also retains cine-oriented manual control behavior for operators who prefer traditional focus techniques.

Mechanically, the AF Cine Line 28-105mm T3 FF follows professional cinema standards with integrated 0.8 MOD gearing for focus, zoom, and iris operation. The lens housing is constructed from durable metal materials designed to withstand demanding production environments while remaining compact enough for lightweight rigs and stabilizer systems.

The standardized 95mm front diameter ensures compatibility with professional matte boxes and accessory systems commonly used in cinema production. The overall design focuses on production flexibility, allowing the lens to function effectively across studio, handheld, travel, documentary, and commercial shooting environments.

Its combination of autofocus capability, extended zoom coverage, and cine-oriented mechanical construction makes the AF Cine Line 28-105mm T3 FF a practical all-in-one cinema zoom solution for productions that prioritize speed, flexibility, and professional image quality.
