What these focal lengths actually give you on the Panasonic Lumix G9
The Panasonic Lumix G9 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 G9 frames like 100mm, not the "normal" view its marked number implies.
