Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. A number lower than 30-50 mm will take in a bigger view than you naturally see, while higher numbers mean focus will be on a smaller aspect of your view.

Lenses can be classified into subgroups like prime, macro, wide angle, normal, telephoto, and zoom lenses. They’re also rated in regards to f-stop or speed. An example would be a 50mm f/2.0 lens or an 80mm f/1.4 lens.
How do you read a camera lens?
- The first number gives the range of focal lengths in millimeters, while the second gives the lens speed (for the 1.4/50 designation it’s vice-versa).
- The first number or pair of numbers indicates the range of available focal lengths in millimeters.
- The lens speed is listed after the small “f” and the slash.
