The camera is just a tool.
I worked on a film where the producer/director bought his own 35mm camera package, lenses, complete Steadicam package, dozens of lights, and production gear. We estimated he spent over $150,000.
He wanted to make his first feature. Which would also be his first film. He found young and talented actors and crew. But, he was only paying his crew $100/day. This would be a problem. The reason we agreed to work for $100/day was because we lacked experience.
Each day, we were focused on how the equipment worked. We should have been focused on the story. In addition, the producer/director was always worried about his investment – the gear. His focus on the film suffered. As a result, the final film could have been better. Lesson learned.
