This. You don't need anything other than a phone to be a lifestyle vlogger. Just get started with your phone and from there you can gather some research on what cameras are good. There's a guy called "Camera Conspiracies" that does humorous camera reviews and actually shows the cameras in action. To be honest, YouTube would be your best friend here. We can give you some camera brand and model suggestions, but you'll find plenty more options as well as actual real world footage examples on YouTube.
"best camera for beginners" in YouTube will probably show you everything you need. Roberto Blake is also fantastic with camera knowledge.
I use the Sony HX80 (less expensive than most) good quality and mega zoom! flip screen etc.. All included.
Lightweight too. Just an idea and option. (is it the best?) nope.... but for the price it's a very good one.
