Sigma 28-105mm T3 Cine Zoom Lens with AF (Sony E, Feet)

Overview

The Sigma 28-105mm T3 Cine Zoom Lens with AF (Sony E, Feet) is a full-frame cine zoom designed for filmmakers who want the flexibility of a versatile focal range together with selectable autofocus performance. Based on Sigma's popular 28-105mm DG DN Art optical design, it combines strong image quality, smooth cine-style operation, and reliable handling for narrative, documentary, gimbal, and handheld productions.

Covering a practical 28 to 105mm range with a constant T3 maximum aperture, this lens is built to move easily between wide, normal, and short telephoto perspectives. Its cinema-oriented mechanics, autofocus capability, 12-blade iris, and professional-standard gearing make it well suited to modern hybrid production workflows.

Core Features

• This full-frame cine zoom offers a versatile 28 to 105mm focal length range for everything from wide establishing shots to tighter portrait and detail work.
• Its constant T3 maximum aperture provides consistent exposure control throughout the zoom range.
• Selectable autofocus and manual focus operation make it suitable for fast-paced productions, handheld work, gimbal setups, and documentary shooting.
• A linear motor HLA system supports responsive autofocus tracking for moving subjects and rapid focus changes.
• The 12-blade iris helps create soft, rounded bokeh for a more cinematic image style.
• Cinema-style mechanics include a limited-rotation focus ring, clickless iris ring, and 0.8 MOD gears for focus, iris, and zoom control.
• A 95 mm front diameter and 82 mm filter thread support compatibility with a wide range of matte boxes and screw-in filters.
• The included removable support foot features a 1/4"-20 thread for integration with optional lens support systems.

Autofocus Performance for Production

Unlike traditional cine lenses that are fully manual only, this model adds autofocus capability for productions that need faster subject tracking and more flexibility on set. It is particularly useful for action scenes, documentary work, gimbal operation, and other situations where maintaining precise focus manually can be more difficult.

Optical Quality Based on Sigma Art Design

Drawing from Sigma's DG DN Art optical platform, the lens delivers strong resolution, attractive bokeh, and a clean, controlled image across the zoom range. It is designed to maintain image quality across different focal lengths and focus positions while minimizing flare and ghosting.

Cine-Friendly Handling

The lens is engineered for cinema workflows with industry-standard 0.8 MOD gearing, a damped feel across the control rings, and reduced metallic noise at the ends of lens travel. These refinements support smoother operation for focus pullers and operators working in professional production environments.
