Using the Sony HXC - D70 studio camera is straightforward. First, you'll need to connect an external power supply as it doesn't come with one. Since it doesn't have a battery included, make sure your power source is stable during use. When setting up, keep in mind that the viewfinder is missing, so you'll need to rely on other display methods. This model doesn't track hours, so you won't have a record of usage time. For maintenance, keep the camera clean and store it in a dry place. Regularly check the B4 mount for any signs of wear and tear. Avoid exposing it to extreme temperatures or humidity to ensure its longevity.
