Lens is very good and sharp even at wide open. I purchased it for Night photography and Milky way photo, I still have to use it for that purpose.

Very fast, relatively sharp lens with minimal defraction, used specifically for aurora and astro for a season and pretty happy with it. Very comparable to the sony 20mm 1.8, but takes up about twice the space in your camera bag. Over all a pretty good lens for the money.

With the SIGMA 20mm F1.4 DG DN Art Lens for Sony E, astrophotography enthusiasts and professionals can capture the night sky with unparalleled clarity and precision. This lens, bundled with Hoya 82mm UV and CPL filters, is a part of the esteemed SIGMA Art line, known for its pursuit of the highest optical performance and rich expression.
The full-frame SIGMA 20mm F1.4 DG DN Art Lens is a mirrorless version of the SIGMA 20mm F1.4 DG HSM Art, boasting a unique specification of a maximum aperture of 1.4 and an ultra-wide angle of 20mm. This compact lens offers photographers overwhelming optical performance and unlimited potential for ultra wide-angle creativity.
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 the darkness of night, focused to infinity, the 20mm F1.4 DG DN Art captures stars in the sky as clear, precise pinpoints of light.
The state-of-the-art optical design and the large, high-precision double-sided aspheric glass front element allow for a front filter thread without any compromises regarding optical performance or size. The addition of a rear filter holder and a variety of useful switches further increases the creative possibilities and easy usability of the lens.
The SIGMA 20mm F1.4 DG DN Art Lens 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.
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 Lens 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 usability.
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. Manufactured in Japan with an uncompromising approach towards every single detail, the SIGMA 20mm F1.4 DG DN Art Lens offers photographers an exceptional experience with high-end results even in the most difficult conditions.
