Recommendation needed: price conscious 50mm prime for XE4.

I am looking to expand my lens collection by actually buying a second prime lense for my fujifilm xe-4.As of right now I only own the 27mm pancake kit-Lense and I would love to get my hands on a 50mm prime lense as an additional multi-purpose lense.The price tag for Fuji 50mm ist quite steep and I am not yet experienced enough to actually discern the pro/cons of alternative manufacturers.So I would love to get some recommendations and perspectives on “cheaper” 50mm prime lenses.Any help and information is highly appreciated.
