Using the Sony PXW - X320 XDCAM camcorder is quite straightforward. First, make sure you have a compatible power source as it doesn't come with a power supply. You can use an external battery or a proper power adapter. When recording, find a stable position for the camcorder to get clear footage. To maintain this camcorder, keep it clean. Use a soft, dry cloth to wipe the body and lens regularly. Also, store it in a dry and cool place when not in use. Avoid exposing it to extreme temperatures or humidity. And remember, always handle it gently to prevent any internal damage.
