Sigma's groundbreaking Art-line 50mm f/1.4 — the lens that proved third-party could match first-party optics.
The Sigma 50mm f/1.4 DG HSM Art launched in 2014 as one of the most important third-party lenses ever made. It proved conclusively that Sigma's Art line could match or exceed the optical quality of Canon and Nikon's own fast 50mm primes, reshaping the industry.
Optically outstanding — sharper than the Canon 50mm f/1.4 USM and Nikon 50mm f/1.4G at every aperture. The Art-line design uses 13 elements with premium glass for exceptional resolution and contrast. HSM motor is fast and quiet. Smooth, creamy bokeh rendering.
Available in Nikon F mount with 77mm filter thread. Weighs 815g — significantly heavier than first-party 50mm f/1.4 lenses. No weather sealing. Minimum focus distance 40cm. USB dock compatible for AF fine-tuning. Thermally Stable Composite barrel.
Very common used and excellent value. The 815g weight is the main drawback. AF calibration via USB dock is recommended. The Sigma 50mm f/1.4 DG DN Art for mirrorless is the successor. One of the most important lenses of the 2010s — it changed how photographers view third-party glass.
