The Sigma 50mm F1.4 DG HSM | A lens is simply amazing. This standard field of view, fast-aperture, full-frame, prime lens combines outstanding sharpness and fast autofocus, in a lens that is built with a singular vision focused on performance.
Initial reviews and fan feedback about the Sigma 50mm F1.4 DG HSM | A lens has been off the charts. The worldwide demand for this lens in all supported mounts is, and will continue to be, very high for the foreseeable future. Thousands upon thousands of photographers have rediscovered Sigma, and are anxiously awaiting delivery of the most highly sought-after lens of the year.
And after having this newest Sigma Art lens in my hands for a few weeks now, I can totally understand why demand is so high. This lens truly is a masterpiece of design both inside and out.
It feels so good in the hands. It is well-balanced despite its notable heft (just under 29 ounces!), with a well-damped manual focus ring, and the hallmark styling of the Art line: a decisive AF/MF switch with hand-painted white backing to quickly visually discern AF or MF operation, year of manufacture stamp, included lens hood that indicates it pairs with the 50mm, and of course, USB Dock and Sigma Optimization Pro compatibility, with an additional new feature added in to lens customization. From an optical perspective, it truly is superlative, and genuinely demands to be described in the most lofty of terms.
Focal plane detail is astoundingly sharp, even at widest apertures, and gets even sharper as it is stopped down a touch. Even details along the edges of the frame—wide open—are rendered crisply. And the defocused areas are just dreamy. Close focus is just about nine inches from the front element at 1:5.6 magnification, so foreground objects can be given hero treatment with very shallow depth of field, even when stopped down a fair bit. (Depth of field is tied to focal length, focal distance, aperture, and sensor size. Learn much more here.)
As with all Sigma Global Vision lenses, each and every 50mm F1.4 DG HSM | A lens that is built is individually tested on the A1 MTF device to ensure its performance is within tolerances before leaving the factory in Aizu, Japan. And from there, it gets queued into the shipment lists of worldwide pre-orders and backorders for this world-beating lens. (You can learn more about our exclusive A1 MTF Charts here, and learn why Sigma chooses to share both Geometric and Diffraction MTF charts for new lenses here.)
There was a lot of reader excitement when I wrote about the first of the Art lenses to be released, the35mm F1.4 DG HSM | A back in November 2012, about what Sigma was up to with the reinvention of the lens lines; but it truly pales in comparison to the level of enthusiasm surrounding the new Art 50mm F1.4. The 35mm F1.4 | A made a statement about what a Sigma Art lens designation means. And then the 18-35mm F1.8 DC HSM | A made an even louder statement followed by a giant exclamation point, by being the world’s first constant-aperture F1.8 zoom lens, with prime-beating performance. And now, with 50mm F1.4 DG HSM | A, Sigma is raising the bar even higher. This is now the standard lens that defines the category, bar none.
