Sigma Announces the New 20mm f/1.4 DG DN Art for Mirrorless Cameras

As rumored some days ago, Sigma has announced the 20mm f/1.4 DG DN lens for L-mount and Sony E-mount cameras. It is the first and only lens of this specification, joining its predecessor – the 20mm f/1.4 DG HSM Art – as the only 20mm f/1.4 lens available for full-frame platforms.

With superb optical clarity from corner to corner, outstanding build quality with a dust and splash-resistant structure, and new details that consider the needs of discerning users, the new Sigma 20mm f/1.4 DG DN Art is optimized for astrophotography while offering performance that makes it an excellent choice for anyone looking for a high-quality, wide-angle prime lens. In addition to its impressive imaging capabilities and premium Art line features, the lens introduces a Manual Focus Lock, which allows the user to set the focus manually and lock it in place, especially useful for time-lapse shooting or long exposures. A new Lens Heater Retainer keeps this useful astrophotography weather accessory firmly in place while in use. A Rear Filter Holder provides an opportunity to use rear-mounted filters for various effects without causing distortion or vignetting. And a convenient front filter thread allows users also to utilize commonly available 82mm filters.

With 17 glass elements arranged in 15 groups, including two SLD, three aspherical glass elements and the largest class double-sided aspherical glass element in Sigma’s history, the 20mm f/1.4 DG DN Art rigorously suppresses various optical aberrations such as sagittal coma flare or image distortion to produce highly-detailed images with exceptional sharpness and accuracy from the center to the furthest corners, allowing photographers to make use of the entire field of view afforded by its ultra-wide viewing angle. The lens also comes with a rear filter holder, allowing photographers the freedom to combine multiple filters to suit a huge variety of shooting situations for near-unlimited creative potential at an ultra-wide viewing angle — for example, using a front filter to reduce light pollution and a softening filter on the rear to take impressive photographs of nightly landscapes with star-filled skies.

Its dust- and splash-resistant structure and the water- and oil-repellent coating on the front glass element make the Sigma 20mm f/1.4 DG DN Art safe to use during longer outdoor shoots, especially during the night. Thoughtful features such as a focus mode switch, a customizable AFL button, and an aperture ring lock switch enhance the lens’s usability. An aperture ring click switch can be used to turn the aperture ring click on and off, allowing photographers to enjoy the sound and feel of the click, as well as smooth aperture operation during video recording. The robust body is built from a combination of aluminum and Thermally Stable Composite (TSC), giving it a sleek finish, and the included petal-shaped lens hood is equipped with a lock mechanism to keep the hood securely fastened to the lens. The rubberized grip area makes attaching and removing the hood a quick and easy process.

The new Sigma 20mm f/1.4 DG DN Art lens will be available for both Sony E-mount and L-Mount systems for a retail price of $899 in late August 2022.
