Software zoom makes the picture more noisy, but when digitizing text documentation, various diagrams and drawings, the quality of the picture with digital zoom practically does not decrease. The main advantage of digital zoom is the affordable price. Additionally, these cameras are typically smaller, lighter, and more durable than models with optical analogue zooms.
