Verdict. 20mm f/1.8 lenses are relatively common but this Sigma goes two-thirds of an f/stop faster at f/1.4, becoming a world-first for full-frame cameras. The extra light-gathering potential is great for shooting landscapes at twilight, architectural interiors and the night sky. With impressive build quality, image quality and overall.
Sigma 20mm f1.4 DG DN Art review Cameralabs
The Sigma 20/1.4G Art is the latest lens in Sigma's line-up of wide-angle "Art" lenses. You can produce shots with image quality that were impossible at a wide open aperture of f1.4 not long ago. It has relatively little vignetting for such a wide-angle lens and shows only little longitudinal CAs and moderate coma. All technical specifications for the Sigma 20mm f/1.4 Art lens have been provided by Sigma: Aperture range: f/1.4-f/16. Angle of view: 94.5°. Aperture ring: Yes, with click and lock switch. Minimum focus distance: 23cm / 9.1 in. Maximum magnification ratio: 1:6.1. Optical design: 17 Elements in 15 Groups. Diaphragm blades: 11, rounded. DN is the designation Sigma uses for its purpose designed mirrorless lenses, so, while there is an existing 20mm F1.4 ART lens for Sony E and Leica L, that lens is a "ported" DSLR lens (essentially with a built in adapter to allow autofocus to work properly and to move the optical path forward for proper focus on a camera without a mirror. At f/1.4, the 20mm lens is slightly sharper in the center and the 24mm is slightly sharper in the corners. By f/2.8, the centers are equalized, but the 24 takes a stronger lead in the corners. The 20mm has slightly more vignetting and shows modestly less flare and distortion. The 24mm is lighter and costs modestly less.

Sigma's "Art" series tend to have a superb build quality, and the 20mm f/1.4 is no exception to this rule. Besides some metal parts, Sigma uses a new material called TSC (Thermally Stable Composite) which contributes to the high-quality perception. The broad focus ring is nicely rubberized and operated smoothly. The Sigma 20mm f1.4 DG DN Art costs 999 EUR / 899 USD / 859 GBP and is made in Japan. It was announced in August 2022 together with Sigma's 24mm f1.4 DG DN Art complementing the Sigma 20mm f2 DG DN and Sigma 24mm f2 DG DN of their Contemporary line. And Sigma still sells the 20mm f1.4 DG HSM Art and 24mm f1.4 DG HSM Art designed for DSLRs. The Sigma 20mm f/1.4 Art lens sells for £849 ($899), which seems very reasonable for what it offers and the high quality of the results. Finding a competitor is difficult as there are no other. Into the fray launches the Sigma 20mm f/1.4 DG HSM ART lens. At a little under $899 (£800) it's not the cheapest of the cheap, but nor is it the Sigma 14mm f/1.8 DG HSM ART. It's a great.
Sigma 20mm f/1.4 DG DN 'Art' lens review (fullframe & APSC) YouTube
The Sigma 20mm F1.4 DG HSM | A is the newest member of Sigma's family of 'Art' lenses. It's also the widest member of the Art lens family, and with a maximum aperture of F1.4 Sigma claims that it's the fastest 20mm lens in the world. We shot this lens on both 5DS R and 7D Mark II bodies, and since we had an EOS mount we even tried it on the Sony A7R II as well. The Sigma 20mm F1.4 DG DN Art's wide angle of view, well-corrected optical formula, and down-to-earth price makes it an ideal lens for creators, particularly astrophotograhpers. MSRP $899.00. $899.
by Adam Ottke December 15, 2015 11 Comments. Not long ago, I released a review of Sigma's newest Art-series lens, the 20mm f/1.4 Art. Unfortunately, Northern California skies have had bit of a. At roughly the same size as the Canon 24-70mm ƒ/2.8L II lens, for example, the Sigma 20mm ƒ/1.4 Art, nevertheless, tips the scales at over 2 pounds compared to the Canon lens' 1.8 pounds.
Sigma 20mm f/1.4 DG HSM Art Review ePHOTOzine
Verdict. Nothing is perfect, and that also applies to the Sigma 20mm f/1.4 DG HSM | Art. HOWEVER, in the grand scheme of things, the lens is very impressive! Ultra-wide lenses are already difficult to design but developing a 20mm f/1.4 lens of acceptable quality is tough, really tough, which tells a lot about Sigma's capabilities. Sunstars on the Sigma 20mm f/1.4 Art are pretty awesome, but because of the rounded aperture blades (which do create nice soft bokeh) the points are not as sharp as the old manual focus lenses from Nikon and Pentax. Also, flare is extremely low, (see above) and overall colors and contrast are fantastic.
