Explanation:

the number is lower, it allows more light in. Sometimes you will see lenses which say 1:2.8. This means that the lens will allow a maximum aperture of f/2.8 throughout the whole zoom range. When there is a hyphen, such as 3.5-5.6, this means that the more you zoom, the narrower the aperture will

Answer when the number is lower, it allows more light in. Sometimes you will see lenses which say 1:2.8. This means that the lens will allow a maximum aperture of f/2.8 throughout the whole zoom range. When there is a hyphen, such as 3.5-5.6, this means that the more you zoom, the narrower the aperture will go.
