Best portrait lens for the sony a6400?
For portraits on the a6400, the lens matters more than the body. Here are three picks from the a6400 lens list, one for each kind of portrait:
- Sigma 28-45mm f/1.8 DG DN Art: about 42-68mm equivalent. Fast and versatile, good for half-length and environmental portraits.
- Tamron 28-75mm f/2.8 Di III VXD G2: about 42-112mm equivalent. A flexible standard zoom if you want one lens for most things.
- Sony FE 50-150mm f/2 GM: about 75-225mm equivalent. Very fast, for tighter head-and-shoulders shots with soft backgrounds.
Whichever you choose, window light will do more for your portraits than any of these. See Light beats gear and the portraits guide. For a broader starting point, see your first lenses.
