Correlation between focal length, angle, | Long focal length | |||
and perspective |
|
|
| |
Focal length, which is measured in millimeters, is the distance between |
| telephoto lens | ||
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.
