Integrating impressive full-frame optics into a compact, lightweight form factor, the Swift 40mm f/2.2 AF Lens from Sirui delivers sharp, true-to-life images with a natural field of view. Boasting an impressive f/2.2 minimum aperture and 1.3' close focus, the standard 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 40mm ensures a consistent aesthetic as focus shifts, making it an excellent choice for vlogs, short films, and other video applications. An 11-element, 8-group optical design with aspherical and ED elements keeps the lens light while suppressing aberrations and enhancing contrast. Offering satisfying, tactile exposure control, the Swift 40mm sports a clicked aperture ring with settings from f/2.2 to f/16, as well as an auto setting.
