Ultra-wide 20mm f/1.4 Art lens for Sony E

This Sigma 20mm f/1.4 DG DN Art lens is built for Sony E-mount mirrorless cameras and delivers a 94.5° angle of view on full-frame sensors. The fast f/1.4 maximum aperture suits astrophotography, landscape and low-light work where wide perspective and brightness matter. The bundle adds an 82mm filter kit, variable ND filter, cleaning supplies and a lens cap tether for immediate use.

Optical design with 17 elements in 15 groups

The lens uses 17 elements arranged in 15 groups, incorporating FLD, SLD and aspherical glass to control aberrations across the frame. An 11-blade rounded diaphragm produces smooth, circular bokeh when isolating subjects at wide apertures. The optical formula is optimised for edge-to-edge sharpness even at f/1.4, which is the practical limit of this design.

Bright aperture and filter thread for creative

The constant f/1.4 aperture provides strong low-light capability and shallow depth of field for a 20mm prime. The 82mm front thread accepts the included filter kit and VND filter, giving flexibility for long exposures and glare reduction. Photographers needing zoom versatility or a narrower field of view will need a different focal length.
