One limit of this table: it lists only Fujifilm X lenses that mount natively on the Fujifilm X-S20 — lenses fitted through an adapter are not included here. See which mounts adapt to which.

What these focal lengths actually give you on the Fujifilm X-S20

The Fujifilm X-S20 has an APS-C sensor, so it sees a 1.5× crop of what each lens projects. Every focal length below therefore frames 1.5× tighter than its marked number. A 50mm on the Fujifilm X-S20 frames like 75mm, not the "normal" view its marked number implies.

Effective focal lengths are the marked focal length × the 1.5× sensor crop factor — the field of view, not a change in the lens itself. Aperture and depth of field are unaffected.
