Minimum aperture This is the smallest aperture that can be selected. A minimum aperture of f/22 is fine for most photography and the setting only really needs to be smaller to allow exposure at slow shutter speed s when using faster film in brighter conditions.
The specifications for a given lens typically include the maximum and minimum aperture sizes, for example, f /1.4- f /22. In this case, f /1.4 is the maximum aperture (the widest opening), and f /22 is the minimum aperture (the smallest opening). The maximum aperture opening tends to be of most interest and is always included when describing a lens.
