Wide-angle prime for full-frame Sony E

This 20 mm f/1.4 Art lens covers 35 mm film and full-frame digital sensors on Sony E-mount mirrorless cameras. The fast maximum aperture suits low-light, landscape and architectural work where a wide field of view and shallow depth of field are needed.

Native mount with dock support

The brass bayonet fits Sony E bodies directly and the Hyper-Sonic Motor provides quiet autofocus. Firmware updates and focus adjustments are handled through the optional Sigma USB dock, so no adapter or manual calibration is required.

Optically corrected for sustained sharpness

Two FLD and five SLD elements plus two aspherical lenses control chromatic and spherical aberration across the aperture range. The rounded 9-blade diaphragm maintains smooth bokeh stopped down, while TSC material in the barrel reduces thermal expansion during extended shooting sessions.
