Sigma 50mm T1.5 FF Cine Lens

The Sigma 50mm T1.5 FF Cine Lens is a fully luminous high-speed prime designed for full-frame cinematography. It mounts natively to Canon EF cameras and delivers exceptional optical performance across the entire sensor area. The lens is engineered for 6K-8K shooting, providing ultra-high resolution suitable for demanding professional productions. Focus and iris scales are marked in feet for imperial measurement workflows.

Integration with cinema rigs and accessories

Industry-standard 0.8 MOD gears on the focus and iris rings allow direct attachment of follow-focus units and motorised lens-control systems. The consistent front diameter and gear positioning across the series streamline matte-box use and reduce lens-change downtime on set. Full-frame coverage frees the operator from crop-factor calculations when framing shots. Manual focus and iris control provide the tactile precision required for narrative cinematography.

Optical engineering for flare resistance and bokeh

Computer-based ray tracing from the initial design stage minimises flare and ghosting, preserving contrast in strong backlit conditions. The T1.5 aperture enables clean low-light exposure without pushing sensor gain, maintaining highlight roll-off and shadow detail. Sigma's proprietary A1 MTF system, verified with 46-megapixel Foveon sensors, confirms corner-to-corner sharpness at full aperture. The optical formula renders smooth, natural bokeh that supports the creative intent of high-end productions.
