Nikon 1 J5 or Sony a5100 for Youtube videos?

Hi, I was wondering what a better buy would be, the Nikon 1 j5 or the sony a5100? I already have the Canon 60d but I wanted a smaller more compact camera

The main thing I'm concerned about is the autofocus and video quality.

Which one would you recommend?

How about a real video camera like a camcorder?

After all, a camcorder is specifically designed to shoot video.

I have an older Nikon 1 V2 and I use the high speed video (400 or 1000 fps) when doing swing studies for golfers and baseball players. It does produce fine Full HD video, but when I'm shooting video, I use a real video camera

The a5100 will autofocus better but video quality will be the same because that depends on your skill. I'd rather recommend a Sony Handycam instead. It's small, light, autofocuses even in lower lighting conditions and shoots much longer than any digital camera. It is after all the right tool for recording video.
