Sigma 20mm F1.4 DG DN | Art
Push the limits of wide-angle photography with the Sigma 20mm F1.4 DG DN | Art, the ultimate lens for photographers who refuse to compromise. Built to deliver extraordinary clarity, even in the deepest night skies, this lens brings Sigma’s Art-series optical excellence to mirrorless users.
With a blazing f/1.4 maximum aperture and ultra-wide 20mm focal length, the lens delivers tremendous exposure speed and beautiful subject isolation. Even at max aperture, the sharpness stays impressively high across the whole frame, making it ideal for astrophotography, landscapes, and any scenario where wide views demand detail.
Sigma’s designers have incorporated high-precision double-sided aspheric elements up front, allowing them to include a traditional front filter thread without enlarging the barrel—giving you both creative flexibility and premium control. Added features like a rear filter holder and tactile switches enhance usability in varied shooting conditions.
Compact, solid, and with optical performance to match, the 20mm F1.4 DG DN | Art excels from candle-lit nightscapes to sunrise-to-sunset panoramas. It’s the lens that bridges creative vision with technical excellence.
