As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
Prime wide-angle 20mm f/1.4 lens is designed for full-frame format Leica L-mount mirrorless cameras and can also be used with APS-C models where it provides a 30mm equivalent focal length.
Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.
Two SLD and three aspherical elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure exceptional clarity and contrast. This optical design also helps to control distortion and limit vignetting.
Employs a concave double-sided aspherical element, which provides outstanding edge-to-edge sharpness and optical performance.
