Optical DesignUltra-wide prime lens designed for APS-C-format Sony E-mount mirrorless cameras where it provides a 20mm equivalent to full-frame 35mm focal length.
Bright f/1.4 maximum aperture suits working in difficult lighting conditions and helps to maintain a relatively compact form factor.
14 lens elements in 11 groups provide a sophisticated optical design. Two aspherical lens elements are optimized for distortion and off-axis optical aberration allowing the lens to maintain excellent resolution throughout the entire focusing range.
Four ED (extra-low dispersion) lens elements greatly reduce color fringing and chromatic aberrations to produce greater clarity and color accuracy no matter which aperture you choose.
Designed for smooth video capture, the lens effectively eliminates focus breathing when changing focusing distances while shooting video.
STM autofocus motor provides fast and responsive AF down to a minimum object distance of just 8.7".
Nine-blade diaphragm contributes to a pleasing bokeh quality.
