One limit of this table: it lists only Micro Four Thirds lenses that mount natively on the OM System PEN — lenses fitted through an adapter are not included here. See which mounts adapt to which.

What these focal lengths actually give you on the OM System PEN

The OM System PEN has a Micro Four Thirds sensor, so it sees a 2× crop of what each lens projects. Every focal length below therefore frames 2× tighter than its marked number. A 50mm on the OM System PEN frames like 100mm, not the "normal" view its marked number implies.

Effective focal lengths are the marked focal length × the 2× sensor crop factor — the field of view, not a change in the lens itself. Aperture and depth of field are unaffected.
