Concepts in Photography Correlation between focal length, angle, and perspective Focal length, which is measured in millimeters, is the distance between the middle of the lens to its focal point. It affects the angle and perspective of captured images. A short focal length translates into a wide angle, which allows you to capture a wide shot. A long focal length translates into a narrow angle, which allows you to capture telephoto shots. Short focal length Long focal length telephoto lens narrow angle telephoto shot Look at these photos below and compare the changes. wide-angle lens wide angle wide shot 20 mm angle 50 mm angle 200 mm angle Normally, a lens with a wide angle is suitable for shooting landscapes and a lens with a narrow angle is recommended for shooting sports events or portraits. 19

Correlation between focal length, angle,
and perspective
Focal length, which is measured in millimeters, is the distance between
the middle of the lens to its focal point. It affects the angle and
perspective of captured images. A short focal length translates into a
wide angle, which allows you to capture a wide shot. A long focal length
translates into a narrow angle, which allows you to capture telephoto
shots.

Normally, a lens with a wide angle is suitable for shooting landscapes and
a lens with a narrow angle is recommended for shooting sports events or
portraits.
