Investing in a camera can be a great career move. You don’t need it to get started, but you can always start shooting on a phone and reinvest your earnings to upgrade to a better camera. You can get a decent camera to film your vids in the range of $400 to $1200 USD. 

The amount of money you can spend on amazing equipment is endless, but that is really up to you and not necessary to become a successful Creator.
