Best portrait lens for the panasonic lumix s1r?

For portraits on the Lumix S1R, I'd start with the Panasonic Lumix S 85mm f/1.8. It's the classic portrait length, and it frames as marked on this full frame body. If you want more background blur and can spend more, the Sigma 85mm f/1.4 DG DN Art is the faster option. For a wider look that still suits people, the Panasonic Lumix S Pro 50mm f/1.4 is a good choice.

Whichever you pick, window light will do more for your portraits than the lens. Read the portraits guide for the light tips, and check your first lenses if you're building a kit.
