Best budget lens for the sigma fp l?

For a budget lens on the Sigma fp L, I'd start with a 50mm f/1.8. It's the cheap fast prime my first camera guide recommends for people and low light, and the fp L's full-frame sensor gives it the usual 50mm framing.

If you want something wider, the Viltrox AF 20mm f/2.8 Air is a small, inexpensive option for landscapes and street work.
