The 5 black is the mutts-nuts or the doggies-danglies,voice activated,image stabilisation,4k,video,burst photography,slow-mo,on wide angle for photos it looks like a fish-eye lens so you get a wider field of view,the list is endless,i can keep it in my pocket and use it as a point-and-shoot its small and lightweight,if I drop it its shock-proof,i haven't regretted buying it even for a single moment,i have the remote-control and selfie-cum tripod for it,set it up if your that way inclines,walk towards it,then use the remote to turn it on,all in all a great little camera
