Product Information

Highest optical performance on a new level

The SIGMA 20mm F1.4 DG DN | Art delivers exceptionally detailed results that easily satisfy the high demands of professional photography and other high-end applications. 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 F1.4 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. This ultimate astrophotography lens is the culmination of the unparalleled manufacturing technology of SIGMA’s sole production base in Aizu, Japan, as well as the company’s know-how and experience with large-aperture wide-angle lenses, such as the SIGMA 20mm F1.4 DG HSM | Art, the SIGMA 14mm F1.8 DG HSM | Art and the SIGMA 14-24mm F2.8 DG DN | Art.

Designed for perfect results even in the most demanding conditions

The new MFL (Manual Focus Lock) switch

When the MFL switch is set to “LOCK”, the focus ring operation will be disabled.
This is to prevent the focus ring from accidentally being moved, which would cause out-of-focus images

Support front and rear filters

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, sharp photographs of nightly landscapes with star-filled skies.

Lens heater retainer

Further, the lens also equips a lens heater retainer, meaning that lens heaters used to prevent internal condensation as the temperature drops on longer night shoots will stay securely attached to the barrel without protruding into the image and causing unsightly vignetting. With its brilliant optical power and its full range of useful features despite its compact and lightweight body, the SIGMA 20mm F1.4 DG DN | Art is the ultimate choice when photographing the night sky.

Superb build quality and usability with uncompromising attention to detail

Its dust- and splash-resistant structure* and the water- and oil-repellent coating on the front glass element make the SIGMA 20mm F1.4 DG DN | Art safe to use during longer outdoor shoots, especially during the night.

* Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.
