  • Exceptional low-light performance with fast f/1.4 aperture
  • Sharp detail across the frame from 17 elements in 15 groups
  • Minimal flare and ghosting thanks to Nano Porous Coating
  • Smooth, artistic bokeh from rounded 9-blade diaphragm

Wide-Angle Art Lens for Sony E

The Sigma 20mm f/1.4 DG DN Art Lens is built for Sony E-mount cameras and suits photographers who need an ultra-wide perspective with a very fast maximum aperture. It is aimed at astrophotography, landscape and environmental portrait work where low-light gathering and shallow depth of field are essential.

Dust-Resistant Build with 82mm Filter Thread

A dust- and splash-resistant barrel protects the 17 elements in 15 groups during outdoor use, while a water- and oil-repellent coating on the front element eases cleaning. The 82mm thread accepts the included filter kit and variable ND filter, and the bundle adds a backpack, strap, cleaner and lens-cap tether for daily transport.

f/1.4 Aperture at 20mm Focal Length

The combination of a 20mm focal length and f/1.4 maximum aperture is the decisive specification; it delivers exceptional low-light performance and strong background separation that slower wide-angle lenses cannot match. Photographers who need a smaller, lighter lens or who shoot primarily at narrower apertures will not benefit from this design.

Questions about this item

What Sony E-mount standard does the 20mm f/1.4 DG DN Art lens use, and what aperture does it cap at?

The lens uses the Sony E-mount and its maximum aperture is f/1.4, allowing maximum light intake for low-light and astrophotography work.

What filter thread size do the included 82mm filter kit and VND filter need to fit the lens front element?

Both the filter kit and the variable ND filter are 82 mm, matching the lens front thread so they screw on directly without step-up rings.

How is the lens mounted on a Sony E-mount body, and what step do users often miss when attaching the supplied lens cap tether?

Align the white mount index on the lens barrel with the matching index on the camera, then twist until it clicks; the tether loops through the small slot on the rear lens cap before the cap is seated.
