minimum aperture (highest f-number). Type G lenses are not equipped with an aperture

II Shutter Speed and Aperture
The same exposure can be achieved with different combinations of shutter speed and
aperture.
Fast shutter speeds and larger apertures freeze moving objects and soften
background details,
while slow shutter speeds and small apertures blur moving objects and
bring out background details.
