Can I adapt the sigma 105mm f 1 4 dg hsm art to sony e?
Yes. The Sigma 105mm f/1.4 DG HSM Art is listed for Sony E, so it mounts directly on a Sony E body with no adapter. The lens is made for full frame, and it works on APS-C too, though it frames tighter there, like about 158mm on full frame.
On a full-frame body such as the Sony a7 III or Sony a7R V, you get the 105mm view as marked. On an APS-C body such as the Sony a6400 or Sony a6600, it becomes a strong portrait-length lens.
It's a big, heavy lens, and it isn't stabilised, so budget for a solid support if you shoot slow. For the full picture, see the Sigma 105mm f/1.4 DG HSM Art page, and for portrait focal lengths in general, see portraits.
