What are long lenses?


The Basics:

Long lenses are also known as Telephoto lenses and can be either a prime lens or a zoom lens. Telephoto lenses have the benefit of long optical reach which allows objects which are further away to be viewed.

A Little More Detail:

Aside from being to view object that are further away, telephoto lenses also have a narrower angle of view which helps to isolate subjects from the background.
