Different types of Lenses

Telephoto Lens - A telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. Telephoto lenses are often used by professionals with SLR cameras to capture images at a long distance. Created by Thomas Rudolph Dallmeyer in 1891 this invention will forever change the way photographs are captures in a distance. Uses of this lens from a professional standpoint are not currently known however many fashion photographers use these type of lenses in their shoots here below is an example of a telephoto lens being used.

Marco Lens – A macro lens is a lens with the additional capability of being able to focus closely (this is usually done by introducing a floating element--a piece of glass that does NOT rack in and out with focus in unison with the other elements in the lens). The strict definition is a lens that can achieve 1:1 magnification--that is, the image on the sensor/film is the same size as the object itself. Most true macros are prime lenses, also most macros are extremely sharp because of the floating element. Here below you can see a Macro Lens being used with a fly which is zoomed in very closely all the minuscule details of the fly are shown such as the antennae and the millions of little hairs. This picture personally shows how beautiful nature is being zoomed in. Macro Lenses might be used for documentaries about incest or any other creature whose appearance actually deceives the naked eye.

Wide angle lens- Wide angle lenses is simply having a wider than normal angle of view (and usually a short focal length) which produces an image that is foreshortened in the centre and increasingly slanted in the periphery This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.

Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away.
