Best portrait lens for the nikon d850?
For portraits on the D850, I'd start with an 85mm. The Portraits page makes the point that the lens matters far more than the body, and the D850 is already a strong camera for it.
- Nikon AF-S 85mm f/1.4G is my pick if you want a classic, dependable portrait lens.
- Sigma 85mm f/1.4 DG HSM Art is a sharp, heavy alternative with the same wide aperture.
- Nikon AF-S 85mm f/1.8G is the lighter, easier-on-the-wallet option if you're just starting out.
Before you spend on glass, read light beats gear. A window and a patient subject will improve your portraits more than any lens.
