What is the sirui aurora 85mm f 1 4 good for?

The Sirui Aurora 85mm f/1.4 is a portrait lens at heart. It's an 85mm prime with an f/1.4 maximum aperture, autofocus, and no stabilisation, and it's made for full frame sensors. On full frame it frames as marked, 85mm, which is the classic focal length for portraits: flattering perspective, comfortable working distance, and soft backgrounds. The portraits guide explains why that combination works so well for faces.

It also mounts on Sony E, Nikon Z, L-Mount and Fujifilm X, so check the lens page for the full list of cameras it fits. On APS-C it behaves like about 128mm, which suits tight headshots and distant subjects. At f/1.4 the depth of field is very thin, so stop down to f/2.8 when you need two people sharp at different distances. If you're still building a kit, the lenses page suggests a fast standard prime first, then an 85mm once you know you want portraits.
