IS f 4.0 A large aperture?

Minimum and Maximum Aperture of Lenses
A lens that has a maximum aperture of f/1.4 or f/1.8 is considered to be a “fast” lens, because it can pass through more light than, for example, a lens with a “slow” maximum aperture of f/4.0. That’s why lenses with large apertures usually cost more.

A higher aperture (e.g., f/16) means less light is entering the camera. This setting is better for when you want everything in your shot to be in focus — like when you’re shooting a group shot or a landscape.
