Question

what type of camera lens was used to take this photograph?

telephoto lens
zoom lens
fisheye lens
wider lens

Explanation:

Analyze visual characteristics of the image

The photograph displays an extremely wide, circular field of view with a black circular frame. The straight architectural lines of the building in the background are heavily curved and distorted outward, which is a classic barrel distortion.

Identify the corresponding lens type

A lens that produces a circular image with a $180^\circ$ field of view and strong barrel distortion is known as a fisheye lens.

Answer:

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