Photography: Different Photography Lenses
If you have an advanced digital camera or film camera you probably have the ability to change your lenses. If you don't have this capability this is still an important section for you to read because lenses are critical to capturing stunning photographs.
Lenses are usually categorized by their focal length. Here are some examples of common focal lengths and some symbolic lines that represent their field of view:

Wide Angle Lenses:
Considered to be lenses from the 20mm-35mm lenses. These lenses are the natural choice of landscape, panoramic views and other outdoor scenes with lots of information. In many outdoor instances a wide angle lens may by the only option which allows the photographer to capture all of the desired photographic elements. Generally speaking, the average wide-angle lens has a deep depth of field making constant refocusing less critical.
Here are some tips for using wide angle lenses:

Normal Lenses:
50mm is usually considered a 'normal' lens. They are usually good genera lenses and have an angle of view close to the human eye.
Telephoto Lenses:
Telephoto lenses come in two main categories: Medium telephoto lenses (85- 135mm) and long telephoto lenses (>135mm). Medium telephoto lenses are great for portrait shots because they help isolate the subject from the background and the increased focal length slightly flattens the image and give the picture a more natural and at the same time flattering perspective. Long telephoto lenses are often used for nature, sports and documentary style photography which requires the pictures look as if the viewer is close to the action but for whatever reason the photographer is limited in getting too close by certain physical elements. Like medium telephoto lenses, long telephoto lenses are also good at picking the subject out from the background.
