    In very basic terms, the F-number tells you how much light the lens will let in. It’s not a measurement (like in cm) but a ratio of the focal length of the lens to its diameter.

    The other bit tells you about the focal length of the lens – in this case, from 15cm to ‘infinity’

    I should be able to explain it better!
