Look at Casey Neistat one of the most successful people ever on YouTube, he could afford any camera there was and he used a Canon 80D most all the time. He had talent, came up with crazy great ideas on shots. The footage looked great. He didn't need a Red or an Arri. He was good and knew how to use what he had.
The latest camera is not going to make any one of us really better, skill, talent, understanding every ounce your camera has, desire do that.
