>>3348701Last I checked nobody is turning up to a TV show or movie set with a fucking Nex 7 from 2012. It's not a professional cine camera, it's consumer grade which means made for basic use like vlogging. It's a vlogging camera by definition.
I don't know who hit you on the head and made you think Sony Nex or Alpha are for professional video, especially back in 2012. Most of them don't even have hot shoes, mic/headphone input, etc. They're not intended for serious video.
