Nikon 2137 Overview
As simple as it is versatile, the AF NIKKOR 50mm f/1.8D from Nikon is a compact normal-length prime lens. Its bright f/1.8 maximum aperture is well-suited for working in a variety of lighting conditions and also affords greater control over depth of field for isolating focus. A Super Integrated Coating has been applied to individual elements, and reduces lens flare and ghosting for increased contrast and color accuracy when working in bright and backlit conditions. Also, a rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
Autofocus is not supported by DSLRs lacking an autofocus motor, such as the D3000-series, D5000-series, D40, D40X, and D60, where the lens may be used with manual focus only.
