Sigma's hugely popular Art-line APS-C fast prime — 45/48mm equivalent at f/1.4 with outstanding sharpness.
The Sigma 30mm f/1.4 DC HSM Art launched in 2013 as one of the first lenses in Sigma's transformative Art lineup. Designed for APS-C DSLRs, it provides a ~45mm equivalent normal perspective at f/1.4 with optical quality that shocked the industry for its price.
Optically excellent — sharp from f/2 with very good performance even wide open at f/1.4. The Art-line optical design uses high-quality glass to deliver sharpness rivalling much more expensive lenses. HSM motor provides fast, quiet AF. Smooth bokeh rendering.
Available in Canon EF-S and Nikon F DX mounts. 62mm filter thread. Weighs 435g. No stabilisation. APS-C coverage only. Minimum focus distance 30cm. USB dock compatible for AF fine-tuning — recommended for best results. Thermally Stable Composite barrel.
Very common used and excellent value. The most popular Art-line APS-C prime. Check AF calibration — use the USB dock. The Sigma 30mm f/1.4 DC DN (mirrorless version) is the equivalent for Sony E and MFT. One of the best value fast primes for APS-C DSLRs.
