You're asking two different things: the best camera and the best cheap camera. Those are different things.
Assuming you already have a smartphone, you can that to make video's also. Since you already have it, you don't need to spend a dime. So it's the best $0,00 camera. Now isn't that cheap?
has there anybody who can give the perfect answer to the best cheap camera for vlogging. or What is the best camera for vlogging?
