While they provide convenience, zoom lenses may sacrifice some sharpness and low-light capability compared to primes.

How does aperture affect depth of field in photos?

Aperture directly influences the depth of field, which is the amount of distance between the nearest and farthest objects in a photo that appears acceptably sharp. A wider aperture (lower f-stop number, like f/1.8) creates a shallow depth of field, where the subject is in focus while the background is blurred, ideal for portraits. A narrower aperture (higher f-stop number, like f/16) increases the depth of field, keeping more of the scene in focus, which is beneficial for landscape photography. By adjusting the aperture, photographers can creatively control what is emphasized in their images and how the viewer’s eye is guided through the composition.
