Should you buy the Sigma 50mm f/1.4 DG DN Art Prime Lens?
The Sigma 50mm f/1.4 DG DN Art Prime Lens is the second-generation 50mm Art designed from the ground up for mirrorless bodies at $849. The 14-element optical formula with three SLD and two aspherical elements suppresses longitudinal chromatic aberration that plagued the older DSLR Art version, the new HLA linear stepping motor drives autofocus silent enough for cinema use and snaps from infinity to minimum focus in under 0.2 seconds, the 670g weight saves 145g over the previous Art and brings the lens within range of the Sony GM, the de-clickable aperture ring serves video shooters while still locking firmly for stills, the dust-and-splash-resistant build adds a fluorine front coating, the 11-blade rounded diaphragm renders specular highlights as near-perfect circles even stopped to f/2.8, and the autofocus lock and AFL custom button match GM-tier controls. The trade is the $849 price that erases the older Sigma value gap and a 72mm filter thread that breaks from the 67mm trinity standard.
