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. That works in your favour here: the Sony FE 400-800mm f/6.3-8 G OSS reaches 1200mm of effective reach, which on a full-frame body would need a longer, heavier and far more expensive lens.
