The camera will often have a monitor, so you can see what’s happening while you are filming. If it doesn’t, you can always hook it up to an external monitor. They also have interchangeable lenses. These are very important for getting different types of shots, so when you are choosing a camera to rent, you should also think about the lenses you will need. The cameras will also have controls for changing focus, opening and closing the iris, and more. Different cameras may have more or fewer features than others do. The quality of the footage is what really matters though.
