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.
