The AF-S NIKKOR 50 mm f/1.8G, a bright, fast, 50mm fixed focal length (prime) lens, compatible with Nikon FX-format digital-SLR cameras that offers the pleasing blur characteristics and three-dimensional rendering capabilities possible only with a fixed focal length lens. A new optical design that enables f/1.8 maximum aperture utilises an aspherical lens element, which achieves superior rendering performance for excellent image quality even with shooting in low light.
The built-in Silent Wave Motor (SWM) ensures quiet autofocus operation. What's more, the SWM means that autofocus shooting is also possible when the lens is used with entry-level Nikon DX-format digital-SLR cameras such as the D5100 and D3100, which are not equipped with an autofocus drive motor.
