The Sigma 30 / 1.4 Art is a great fast lens for SLR cameras with an APS-C sensor. Very important: Sigma 30 / 1.4 Art should not be confused with two similar lenses Sigma 30mm 1: 1.4 EX DC HSM (older version) and Sigma 30mm 1: 1.4 DC DN | C (Contemporary) (version only for mirrorless cropped cameras).
