Lens Types:Wide-Angle Lenses
Generally, any lens that provides a wide view of a scene and has a viewing angle of 60 degrees or more is called a wide-angle lens. One characteristic of these lenses is that they make close objects look very close and far-away objects look even farther away, creating a strong feeling of perspective. Also, their high depth of field makes them especially suited to pan-focus photography where all the elements of a scene are in focus, from near to far.

Two Main Wide-Angle Advantages
One advantage is the extreme feeling of perspective created by making a subject look either closer than it really is or farther away. The other advantage is the pan-focus effect where all of a scene's elements, from foreground to background are brought into sharp focus.
Strong perspective effect
Pan-focus effect
Ultra Wide-Angle Lens
Lenses with a focal length of 20mm or less are called ultra wide-angle lenses. One attraction of these lenses is the feeling of scale created by their extreme perspective.
A viewing angle far in excess of the human eye produces a magnificent feeling of scale.
Extreme perspective creates a dynamic image.
Wide-Angle Lens
Lenses with a focal length of 28mm to 35mm are called wide-angle lenses. These lenses provide a good balance of subject and background, and let you take a wide range of photographs, from scenery photos to snapshots.
A wide angle of view and high depth of field keep both the near and far elements of a scene in focus, allowing you to easily take pan-focus photos.
A wide viewing angle creates images with a good balance of subject and background.
Stand closer when using a wide-angle lens!
While a 50mm lens gives roughly the same perspective as the human eye, as you can see here a wide-angle lens makes people appear very small. The key to taking wide-angle pictures of people is to stand close to them. This creates the optimal balance of subject and background.
A 50mm lens image is similar to the human eye.
