Best portrait lens for the sony a6100?

For portraits on the a6100, I'd start with the Sigma 28-45mm f/1.8 DG DN Art. It frames like 42-68mm on full frame, so it's a natural portrait range, and f/1.8 gives you a soft background.

If you want more reach, try the Tamron 28-75mm f/2.8 Di III VXD G2 (about 42-112mm on full frame) for a flexible zoom that's sharp across a range. For a telephoto option with lovely subject separation, the Sony FE 50-150mm f/2 GM (about 75-225mm on full frame) is the one I'd save up for.

Whichever you pick, light matters more than the lens. Put your subject facing a window and expose for the face. There's more on that in portraits, and the lenses guide explains where a portrait lens fits in your kit.
