The Sigma 20mm T1.5 FF High Speed Prime Lens for Canon EF Mount is the combination of high-quality optics and mechanics Global Vision still line in a cine-oriented design. The lens is compatible with full frame, and while being more compact, it can offer superior resolution than other high-end prime sets do. With the seven prime lenses from FF High Speed Prime Line, there is no need to change the lighting to shoot a variety of cuts, and it is possible to meet the demands that professional movie creation requires. The primes offer full-frame sensor coverage, 6-8K resolution, and a fast T1.5 aperture in a compact, lightweight form in Canon EF mounts. The 9-bladed iris produces pleasing out-of-focus "bokeh" effects, and offers consistent lens gear positions and 180° of focus barrel rotation. 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. 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. Select markings are done in luminous paint for easy visibility in low light. A support foot is built into the dust- and water-resistant metal lens body to relieve stress on your camera's lens mount.
