Camera Basics - Aperture

What is aperture?

• The hole in the lens through which light travels into the camera body

• The part of the camera that controls the amount of light entering the camera

• The size of the camera sensor

• The distance between the lens and the camera sensor

What is the function of the diaphragm in the lens?

• To control the size of the aperture

• To determine the amount of light that falls on the retina

• To gather light and bend it inward toward the iris

• To block all light except the light that goes through the aperture

How is aperture expressed in photography?

• In millimeters

• In focal length

• In f-numbers

• In shutter speed

What does a larger aperture (smaller f-stop) mean?

• The image appears blurry

• The image appears sharper

• More light enters the camera

• Less light enters the camera

What is the depth of field?

• The area of the image that appears sharp

• The amount of light that falls on the retina

• The distance between the lens and the camera sensor

• The size of the pupil

What is the maximum aperture of a lens?

• The largest aperture the lens can achieve

• The aperture that isolates either the foreground or background objects

• The aperture that brings all foreground and background objects into focus

• The smallest aperture the lens can achieve

What is the advantage of a fast lens?

• It is better for landscape photography

• It has a larger minimum aperture

• It can pass more light into the camera

• It can zoom without physically moving

What is the disadvantage of using the minimum aperture of a lens?

• The lens produces more noise

• The lens cannot focus properly

• The image appears blurry

• The image loses clarity due to diffraction

What is the difference between prime lenses and zoom lenses?

• Prime lenses have a fixed maximum aperture, while zoom lenses have a variable maximum aperture

• Prime lenses have a fixed focal length, while zoom lenses allow you to zoom in or out

• Prime lenses are better for nighttime photography, while zoom lenses are better for sports photography

• Prime lenses can zoom without physically moving, while zoom lenses require physical movement to zoom

Why are fast lenses important for nighttime photography?

• They can pass more light into the camera

• They have a fixed focal length

• They can zoom without physically moving

• They have a larger minimum aperture
