Photography Lens

STANDARD LENS: A standard lens is a lens that reproduces perspective that looks natural to the human eye, under normal viewing conditions. They have focal lengths about equal to the diagonal size of the film or sensor format. A 50mm lens would be a standard lens for a 35mm camera. This lens has a variety of uses, which can include portrait photography. 

TELEPHOTO LENS: A telephoto lens is a type of long-focus lens where the physical length of the lens is shorter than the focal length. Generally, it is any lens with a focal length over 50mm. Used for close-up photography of objects, people or animals; the telephoto allos you to get optically close to a subject when you cannot be physically close.

WIDE ANGLE LENS: A wide-angle lens refers to a lens whose focal length is shorter than the focal length of a normal lens; any focal length under 50mm. The lens distorts the perspective due to the distance at which the picture is taken. Often used for landscape photography.
