What these focal lengths actually give you on the Panasonic Lumix G9 II

The Panasonic Lumix G9 II 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. That works against you here: the widest option, the OM System M.Zuiko 8mm f/1.8 Fisheye PRO, frames like 16mm — not as wide as its marked number suggests. For a genuinely wide view on the Panasonic Lumix G9 II you want a lens marked around 12mm or shorter.

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.
