What these focal lengths actually give you on the Sony a6400
The Sony a6400 has an APS-C sensor, so it sees a 1.5× crop of what each lens projects. Every focal length below therefore frames 1.5× tighter than its marked number. A 50mm on the Sony a6400 frames like 75mm, not the "normal" view its marked number implies.
