Which focal length would produce a strong telephoto effect?

• A. 18mm
• B. 50mm
• C. 85mm
• D. 200mm

Answer: (D)

A strong telephoto effect comes from using a long focal length lens, which narrows the angle of view and magnifies distant subjects. This magnification makes the subject look larger in the frame while the background appears closer to the subject, a look photographers call compression. Among the options, the lens with the greatest focal length provides the most magnification, giving the strongest telephoto look. The shorter choices behave more like standard or wide-angle lenses, which capture a wider scene and don’t produce as much magnification or compression. So the longest focal length yields the strongest telephoto effect.
