Nikon af s 105mm f 1 4e ed vs sigma 85mm f 1 4 dg hsm art?

Both are full-frame f/1.4 autofocus primes with no stabilisation, so the choice comes down to focal length and mount.

The Nikon AF-S 105mm f/1.4E ED is Nikon F only. It frames tighter, which suits headshots when you can stand further from your subject. On a Nikon APS-C body it reaches about 158mm equivalent.

The Sigma 85mm f/1.4 DG HSM Art is the more flexible buy. It comes in Canon EF, Nikon F, Sony E and L-Mount, and 85mm is the classic full-frame portrait focal length.

If you shoot Nikon and want tighter portraits, get the 105. If you might change systems, or want the more versatile focal length, get the Sigma. For more on how focal length changes a portrait, see the portrait lenses.
