Question

telephoto lens
zoom lens
fisheye lens
wider lens

Explanation:

Identify the lens markings

The image shows a single camera lens in two states: extended (left) and retracted (right). Looking closely at the barrel markings, we can read the focal length range: "28-200" (specifically, "Nikon ED AF NIKKOR 28-200mm").

Analyze the lens behavior

The lens barrel physically extends and retracts, and it features a range of focal lengths from \(28\text{ mm}\) to \(200\text{ mm}\). This ability to change focal lengths by adjusting the internal optics is the defining characteristic of a specific category.

Match with definitions

Using our understanding of Camera Lens Types:

• A telephoto lens has a long focal length (typically \(70\text{ mm}\) or longer) but does not necessarily have a variable focal length.
• A fisheye lens is an ultra-wide-angle lens with severe visual distortion.
• A wide lens has a short focal length (typically under \(35\text{ mm}\)).
• A zoom lens is a lens that has a continuously variable focal length (such as \(28\text{ mm}\) to \(200\text{ mm}\)), which is demonstrated by the physical extension and the range of focal lengths printed on the barrel.

Answer:

• Telephoto Lens
• Zoom Lens (Correct answer)
• Fisheye Lens
• Wider Lens
