Manufacturer description
The 28mm lens is considered today to be the standard wideangle lens by an increasing number of photographers. It is a favorite choice because the typical wideangle effects become obvious at this particular focal length and it has a wide variety of applications including commercial, industrial, architectural, travel, landscape and news photography. Because of the growing popularity of the 28mm lens, Nikon offers three models in different maximum lens speeds. The 28mm f/2 has the fastest lens speed of the Nikkor wideangles with picture angles of 74° and over. This speed permits easy, accurate focusing and facilitates picture taking indoors or under unfavorable lighting conditions. It features the floating element system to achieve excellent results in close-range photography.
Compared with the f/2, the newly-designed 28mm f/2.8 and f/3.5 Nikkors are smaller and more lightweight to ensure easy handling and mobility. In all three lenses, spherical and coma aberrations are well corrected, ensuring uniform sharpness - edge-to-edge - even at full-aperture.
