Integrating impressive full-frame optics into a compact, lightweight form factor, the Swift 20mm f/2.4 AF Lens from Sirui delivers sharp, true-to-life images with an expansive field of view. Boasting an impressive f/2.4 minimum aperture and 7.9" close focus, the wide-angle prime offers striking foreground detail and background separation for close-ups, as well as corner-to-corner clarity for wide shots and landscapes.
Featuring natural color rendering, low distortion, and minimal focus breathing, the Swift 20mm ensures a consistent aesthetic as focus shifts, making it an excellent choice for vlogs, short films, and other video applications. An 11-element, 9-group optical design with aspherical, ED, and HRI elements keeps the lens light while suppressing aberrations and enhancing contrast. Offering satisfying, tactile exposure control, the Swift 20mm sports a clicked aperture ring with settings from f/2.4 to f/16, as well as an auto setting.
