What these focal lengths actually give you on the Panasonic Lumix GH7

The Panasonic Lumix GH7 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 Panasonic Lumix GH7 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.
