What is the term used to describe the ability of a lens to maintain focus on a moving subject?

  1. Autofocus

  2. Manual focus

  3. Image stabilization

  4. Aperture control


Correct Option: A
Explanation:

Autofocus is a feature that allows the lens to automatically adjust its focus to keep a moving subject sharp and in focus.

Which type of lens is commonly used for capturing portraits?

  1. Wide-angle lens

  2. Prime lens

  3. Telephoto lens

  4. Macro lens


Correct Option: B
Explanation:

Prime lenses, particularly those with focal lengths in the range of 50mm to 85mm, are often preferred for portrait photography due to their ability to produce sharp and flattering images.

What is the primary advantage of using a zoom lens over a prime lens?

  1. Increased magnification

  2. Wider field of view

  3. Versatility and flexibility

  4. Improved image quality


Correct Option: C
Explanation:

Zoom lenses offer versatility and flexibility by allowing photographers to adjust the focal length within a range, providing the ability to capture a variety of shots without changing lenses.

Which type of lens is commonly used for capturing sports and action photography?

  1. Wide-angle lens

  2. Prime lens

  3. Telephoto lens

  4. Macro lens


Correct Option: C
Explanation:

Telephoto lenses with long focal lengths are often used for sports and action photography, allowing photographers to capture distant subjects with clarity and detail.

What is the term used to describe the ability of a lens to produce sharp images at different distances?

  1. Depth of field

  2. Aperture

  3. Focal length

  4. Resolution


Correct Option: A
Explanation:

Depth of field refers to the range of distances in an image that appear sharp and in focus.

Which type of lens is commonly used for capturing wildlife and nature photography?

  1. Wide-angle lens

  2. Prime lens

  3. Telephoto lens

  4. Macro lens


Correct Option: C
Explanation:
