Sigma 85mm f 1 4 dg dn art vs meike 85mm f 1 4 ii?
Both are 85mm f/1.4 autofocus primes for full frame. Neither has stabilisation, and both frame the same way: 85mm on full frame, or about 128mm equivalent on APS-C. The main difference is mounts. The Sigma 85mm f/1.4 DG DN Art fits Sony E and L-Mount. The Meike 85mm f/1.4 II also fits Nikon Z, so if you shoot Nikon Z, Meike is your only choice of the two.
If you shoot Sony E or L-Mount, pick the one whose brand you trust more. I don't compare prices or sharpness on this site, so check current prices yourself before you buy.
Either lens is a classic portrait choice. For how to use an 85mm for people, see portraits.
