SIGMA has released the full-frame mirrorless version of its popular 20mm F1.4 DG HSM | Art for the L-mount and Sony E-mount. The new SIGMA 20mm F1.4 DG DN | Art features an ultra-wide-angle 20mm, a bright maximum aperture of F1.4, support for both front and rear filters, dust- and splash-resistant structure, water- and oil-repellent coating on the front glass element and, for those who shoot at night in colder temperatures, a Lens Heat Retainer to prevent internal condensation as the temperature drops on longer night shoots. It’s a great lens for landscape, low-light, night, and astro photography.



An Art level 20mm F1.4. The ultimate lens for astrophotography.

Outstanding optical quality and a range of invaluable features – The ultimate astrophotography lens from the 20mm F1.4 pioneer

The F1.4 series represents the SIGMA Art line, which pursues the highest optical performance and rich expression. The full-frame SIGMA 20mm F1.4 DG DN | Art is a mirrorless version of the SIGMA 20mm F1.4 DG HSM | Art; the one and only lens* with its unique specification of maximum aperture of 1.4 and an ultra-wide angle of 20mm. This lens offers photographers overwhelming optical performance and unlimited potential for ultra wide-angle creativity at a compact physical size. The exceptional F1.4 brightness and the breathtaking sharpness across the entire image even at maximum aperture make this lens the ultimate choice for astrophotography. In nightly darkness and focused to infinity, the 20mm F1.4 DG DN | Art captures stars in the sky as clear, precise pinpoints of light. State-of-the-art optical design and the large, high-precision double-sided aspheric glass front element made it possible to add a front filter thread without any compromises regarding optical performance or size. The addition of other invaluable features such as a rear filter holder and a variety of useful switches further increases the creative possibilities and easy usability of the lens. Its incredible sharpness and very bright aperture, coupled with the compact body and thoughtful features, make the SIGMA 20mm F1.4 DG DN | Art the ultimate lens for astrophotography and an ideal companion for any photographically demanding situation.
