But you have to be objective. This is not a 4k camera. This is a 1080p camera. Choosing between the SJ4000 and Sj4000AIR, I leaned in favor of the latter because of the ability to shoot 60 frames / s in 1080p (for riding a motorcycle, where image dynamics are very important). Of the other SJCAM cameras, only the SJ5000x Elite can do this (and it costs 2-3 times more).
