Sigma's Fully Luminous FF High-Speed Cine Prime Lenses combine the same high-quality optics and mechanics of their Global Vision still line in a cine-oriented design. This 65mm Canon EF-mount prime is a longer normal focal length in the series, offering full-frame sensor coverage, 6K to 8K resolution, and a T1.5 aperture in a compact, lightweight form. Electronic contacts in the mount provide lens data communication between the lens and the camera. A common 95mm front diameter and similar physical attributes across the lens line make it easier and quicker to mount lens accessories such as matte boxes, follow focuses, and lens control motors. Focus marks are in feet and fully luminous for easy visibility in low light.

The 9-bladed iris produces pleasing out-of-focus bokeh effects, and ghosting and flaring have been minimized. Color reproduction is standardized for easier color correction. Each lens in the range offers consistent lens gear positions and 180° of focus barrel rotation. The FF High-Speed Primes also feature a clickless iris with linear markings, dampeners on each gear ring for silent operation, industry-standard 0.8 module gear pitch, and engraved markings for durability.

To relieve stress on your camera's lens mount, a support foot is built into the dust- and water-resistant metal lens body. If you wish to fit your FF High-Speed Prime lens to a different camera, the Canon EF and Sony E mount versions can be converted from one to the other by an authorized Sigma service center (not available for PL mounts).
