Sigma 28mm T1.5 FF High-Speed Prime (EF Mount)

The Sigma 28mm FF High-Speed Prime Lens for Canon EF-mount delivers professional cine-quality optics in a compact, lightweight package. Designed for full-frame sensors, it supports 6–8K resolution and features a fast T1.5 aperture, ideal for low-light shooting and creative shallow depth-of-field control. The lens shares a standardized 95mm front diameter and physical design with other FF High-Speed Primes, making it simple to mount accessories like matte boxes, follow focuses, and lens control motors consistently across the line.

Optimized for cinema use, the lens includes a 9-blade iris for smooth bokeh, clickless linear-marked iris, and dampened gear rings for silent operation. Ghosting and flare are minimized, and color reproduction is standardized for easier color grading. Focus barrel rotation spans 180° with consistent gear positions, and select markings use luminous paint for visibility in low-light conditions. The lens body is metal, dust- and water-resistant, and features a support foot to relieve stress on the camera mount.
