Nikon 50 mm f/1.8D AF Nikkor
From Wikipedia, the free encyclopedia
The Nikon 50 mm f/1.8D AF Nikkor is one of Nikon's 50 mm lenses. A 50 mm prime lens is the normal lens for the 35 mm format. On a Nikon DSLR, a 50 mm lens is cropped to the angle of a view of a short telephoto lens (75 mm equivalent on DX format cameras; field-of-view crop is 1.5). 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.
