The maximum aperture of an object can determine in which light settings pictures can be taken. Aperture is expressed by the f-stop number in different forms. For example, f/8, F8 and 1:8 refer to the same aperture. Lenses with maximum aperture (low f-stop number) are light intense objects, enabling faster shutter speeds.This means tripods and flash units are needed less and it is possible to control depth of focus. The object appears brighter through the lens which makes focusing easier.
Lenses with lower maximum aperture (higher f-stop numbers) enable slower shutter speed and are furthermore lighter and more compact than more light intense lenses. At Nikon you can choose from a variety of Nikkor lenses with the same focal lengths but different maximum aperture.
