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. That matters for portraits: an 85mm frames like 170mm on the Panasonic Lumix G9, which is tight for head-and-shoulders in a small room. A 50mm gives you the classic 100mm portrait look instead.

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.
