Optical Design

• Ultra-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.
