Sigma 28-45mm T2 Cine Zoom Lens with AF (Sony E, Feet)

Overview

The Sigma 28-45mm T2 Cine Zoom Lens with AF (Sony E, Feet) is a full-frame cine zoom designed for filmmakers who want the speed of a fast T2 aperture together with the flexibility of selectable autofocus. Based on Sigma's popular 28-45mm f/1.8 DG DN Art optical design, it combines strong image quality, cinema-style handling, and responsive autofocus performance for narrative, documentary, gimbal, and handheld production.

With a 28 to 45mm focal length range, this lens is well suited to wide establishing shots, tighter medium framing, and dynamic moving-camera work. Its bright aperture, rounded 11-blade iris, cine-standard gearing, and professional mechanical construction make it a practical option for modern hybrid cinema workflows.

Core Features

• This full-frame cine zoom covers a versatile 28 to 45mm range for wide-angle and standard framing in professional productions.
• Its fast T2 to T16 aperture range enables strong low-light performance and greater creative control over depth of field.

Advanced Optical Design

Derived from Sigma's 28-45mm f/1.8 DG DN Art lens, this cine zoom is designed to deliver strong sharpness, attractive bokeh, and controlled flare and ghosting across the zoom range. The result is a clean, polished image suited to high-end cinema capture.

Autofocus for Modern Production

Unlike traditional manual-only cine lenses, this model adds autofocus capability for productions that need faster subject tracking and more flexibility on set. It is particularly useful for action sequences, handheld operation, gimbal work, and documentary shooting where maintaining manual focus can be more demanding.

Professional Mechanical Construction

The lens combines Sigma's proven Art-series rendering with cinema-oriented mechanics built for production use. Standard 0.8 MOD gearing, damped control rings, and reduced metallic noise at the ends of travel help support smoother operation for assistants and operators in professional shooting environments.
