A 12-blade aperture helps produce smooth, pleasing bokeh, contributing to a dramatic, filmic look while maintaining strong optical performance across the zoom range.
Combining professional cine ergonomics with modern autofocus capability, the 28-105mm T3 FF Cine Zoom offers filmmakers a flexible lens solution for dynamic shooting scenarios.
AF Tracking System
Equipped with a linear motor HLA (High-response Linear Actuator), the Sigma AF Cine Line captures intense movements in action scenes, rapid focus shifts in gimbal or handheld shooting, and unpredictable moments in documentaries without missing a split second.
Advanced Optical Design
The Sigma 28-105mm T3 FF incorporates the optical system of its DG DN Art still photography lens. These lenses deliver exceptional resolution and beautiful bokeh regardless of focal length or focus position, along with a sharp, clean look with minimal flare and ghosting.
Professional-Grade Mechanical Design

All three lens gears are standard 0.8 MOD and feature a damper that eliminates metallic sounds when you reach the end of the lens travel.
Lens Front
The lens features a 95mm front diameter for compatibility with a wide variety of matte boxes and incorporates an 82mm front filter thread.
Support Foot and Thread
The lens includes a removable foot with a 1/4"-20 thread for use with an optional lens support system.
