One of the biggest advantages of using a zoom lens is that it allows you to change focal lengths without changing your lens. A zoom lens also provides a range of variable focal lengths which can be adjusted using the zoom ring on the lens. Because of this inbuilt versatility – zoom lenses are complex with lots of close tolerance components sliding and rotating within each other. This is fine under normal conditions, but at extremely low and high temperatures or in the vacuum of space producing these movements presents a challenge.
