Prime Lens - Beginner-Photography-Guide

A prime lens operates with only one focal length.

It is described as a fixed-focal-length lens while, in comparison, a zoom lens has varying focal lengths.

When using a prime lens there is no ability to zoom the lens to change the composition.

Therefore, if you want to change how much of your subject fits “within the frame” you may need to move closer or farther away.

In comparison, by rotating a lens zoom ring you have the ability to move your subject closer to you, or farther away.
