Which lens is best for capturing distant subjects with a magnified view?

• A. A wide field of view and short focal length
• B. A lens that reduces depth of field to zero
• C. A lens optimized for macro close-up
• D. A lens with a longer focal length than standard, giving a narrow field of view and a magnified image.

Answer: (D)

When you want a distant subject to appear larger in the frame, a telephoto lens with a longer focal length is the choice. It narrows the angle of view, so subjects far away are magnified on the sensor, allowing you to fill the frame without moving close. This is exactly what creates a magnified view of something far off while keeping you at a comfortable distance.

A wide-angle lens, with its short focal length, would instead capture a broad scene and make distant subjects look small. A macro lens is designed for close-up work and near distances, not distant subjects, so it won’t provide the same magnification of something far away. The notion of reducing depth of field to zero isn’t practical or the point here—depth of field can be controlled by distance, aperture, and focal length, but magnification of distant subjects comes from using a longer focal length.
