Sigma looked to create a peak portrait prime with the 85mm f/1.4 DG HSM Art Lens, and they delivered an optic with high performance, a large f/1.4 aperture, and a variety of technologies. Available here with a Canon EF mount, this lens offers a super-fast f/1.4 aperture that is great for getting images with an exceptionally shallow depth of field and smooth bokeh. It also uses two FLD elements and one anomalous partial dispersion/high-refractive index element that minimize aberrations and ensures a crisp, clear image. A Super Multi-Layer coating helps by suppressing flare and ghosting.
For operation, a Hyper Sonic AF motor provides fast, accurate focusing and a large focusing ring permits manual focus override for making fine adjustments. A rounded 9-blade diaphragm also helps create round, smooth bokeh. It is made from a thermally-stable composite material that is light and durable and it has a brass bayonet mount. Additionally, it is fully compatible with Sigma's USB Dock.
