Introduction
This lens was introduced on February 21, 2002.
On a Nikon DX format DSLR, a 50 mm lens is cropped to the angle of a view of a short telephoto lens (~75 mm equivalent; field-of-view crop is 1.54). Prime lenses can be cheaper and easier to manufacture than zoom lenses and may have better optical characteristics compared with zoom lenses of comparable price. The combination of low cost and high optical quality makes this a popular lens among many photographers. When used on DX format cameras the resulting angle of view along with its large aperture also make it a lens suitable for portraiture.
Being an F mount lens, it will mount as well as meter on all Nikon DSLRs. The lack of an internal autofocus motor means that this lens can only use manual focus on entry level cameras such as the D40, D60, D3000, D5000, D3100 or D5100; however, a newer version of the same lens, the Nikon AF-S Nikkor 50 mm f/1.8G, will autofocus successfully on these cameras.. With a reverse coupler, one can also reverse mount this lens on to a camera or reverse mount it in front of another lens to use it for macro shots, although it is a procedure not recommended by Nikon.

Famous quotes containing the word introduction:
“The role of the stepmother is the most difficult of all, because you can’t ever just be. You’re constantly being tested—by the children, the neighbors, your husband, the relatives, old friends who knew the children’s parents in their first marriage, and by yourself.”
—Anonymous Stepparent. Making It as a Stepparent, by Claire Berman, introduction (1980, repr. 1986)
“For better or worse, stepparenting is self-conscious parenting. You’re damned if you do, and damned if you don’t.”
—Anonymous Parent. Making It as a Stepparent, by Claire Berman, introduction (1980, repr. 1986)
“Such is oftenest the young man’s introduction to the forest, and the most original part of himself. He goes thither at first as a hunter and fisher, until at last, if he has the seeds of a better life in him, he distinguishes his proper objects, as a poet or naturalist it may be, and leaves the gun and fish-pole behind. The mass of men are still and always young in this respect.”
—Henry David Thoreau (1817–1862)
