Compact Wide-Angle Prime for Sony E-Mount

The Sigma 20mm f/2 DG DN Contemporary lens is a wide-angle prime built for Sony full-frame E-mount cameras. It suits landscape, cityscape, and astrophotography enthusiasts who need a fast f/2 aperture in a lightweight metal body. The kit adds a 10-piece accessory bundle including filters, a cleaning kit, hood, and pouch for immediate protection and maintenance.

Simple Filter Thread and Standard Mount

The lens uses a standard 62mm filter thread that matches every filter and hood included in the bundle, so installation requires no step-up rings or adapters. The stepping motor delivers quiet autofocus suitable for video work. The only common issue is vignetting when stacking multiple 62mm filters, which the slim filter frames in this kit are designed to minimise.

Maximum Aperture f/2 for Low Light

The f/2 maximum aperture is the single specification that determines whether this lens fits a buyer's low-light and depth-of-field requirements. It provides significantly more light gathering than slower f/2.8 or f/4 wide-angle zooms, enabling handheld night-sky and indoor shooting. Buyers who need a wider maximum aperture such as f/1.4 or a zoom range should consider other options.

Questions about this item

How can I verify the 20mm f/2 DG DN Contemporary lens is performing correctly after mounting it on my Sony E-mount body?

Attach the lens, set the aperture to f/2, and shoot a flat, well-lit target at the 8.7 inch minimum focus distance; the image should show sharp detail from centre to corners with no visible distortion.

What accessories are included in the 10-piece bundle and is anything else required to start shooting?

The bundle supplies the lens, a tulip hood, UV/CPL/FLD filter set, separate UV filter, blower, cleaning pen, starter cleaning kit, microfiber cloth, lens cap keeper and an X-large pouch; no further items are needed for basic use.

Which filter-thread size should I match when buying additional filters for this kit?

Every filter and the tulip hood in the kit are 62 mm, so any extra screw-on filters must also be 62 mm to fit the lens front thread.
