Zoom lenses for Sony cameras

Zoom lenses are able to move lens elements. This allows you to capture a subject that is far away, without having to move yourself. You can photograph both portraits and landscapes with one lens, so there's no need to take several lenses with you. Zoom lenses often consist of more lens elements than lenses with a fixed focal point, which is why zoom lenses perform less well when there's a specific focal point than prime lenses do.
