Sigma AF Cine Line 28-45mm T2 FF Zoom

Full Frame Cinema Zoom

The AF Cine Line 28-45mm T2 FF is a compact full-frame cinema zoom lens developed for modern productions that require cinematic image quality combined with the speed and flexibility of autofocus operation. Designed for professional filmmakers, content creators, commercial productions, documentary teams, and hybrid cinema workflows, the lens combines cine-oriented mechanics with advanced autofocus technology in a lightweight production-ready housing.

Covering a versatile focal range from 28mm to 45mm, the lens is particularly suitable for handheld cinematography, interviews, commercials, music videos, social content production, and dynamic camera movement. The focal range allows operators to move quickly between wider establishing shots and tighter medium framings without changing lenses, improving workflow efficiency on fast-paced productions.

The constant T2 aperture provides strong low-light performance while allowing shallow depth-of-field rendering with smooth background separation. Even in challenging lighting conditions, the lens maintains a cinematic image structure with natural focus falloff and balanced contrast reproduction. The optical design is optimized for high-resolution cinema capture and delivers detailed image reproduction suitable for modern 6K and 8K workflows.

One of the key advantages of the AF Cine Line 28-45mm T2 FF is its autofocus integration. The autofocus system supports precise subject tracking and responsive focus transitions, making the lens particularly useful for solo operators, gimbal work, moving camera setups, and productions where manual focus pulling is impractical. At the same time, the lens retains professional cine-style handling with manual control options suitable for traditional cinema operation.

The housing is built for professional production environments and features a robust all-metal construction with cine-standard 0.8 MOD gears for focus, zoom, and iris control. The 95mm front diameter supports compatibility with professional matte boxes and accessory systems commonly used in cinema production.

Despite its fast aperture and cinema-oriented mechanics, the lens remains compact enough for handheld rigs, drones, stabilizers, Steadicam systems, and lightweight production setups. This combination of mobility, autofocus capability, and cinematic optical performance makes the AF Cine Line 28-45mm T2 FF particularly effective for productions that require speed without sacrificing image quality.
