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.You need to give us a budget.
Without that, I'll give you the standard starter recommendation. A phone, a phone cage, an external mic and an external light. Everything besides the phone will run you about $90USD
