Offering an impressively broad field of view, the AF NIKKOR 20mm f/2.8D from Nikon is a compact and lightweight lens well-suited for landscape, interior, and travel photography. Its modest f/2.8 maximum aperture helps achieve a balance between its sleek size and being fast enough for working in low-light conditions. In regard to the optics, a Super Integrated Coating has been applied to individual elements to control flare and ghosting for improved contrast and color rendering when working in bright and backlit conditions. Close Range Correction also helps to ensure consistent image quality and accurate rendering throughout the focusing range. Additionally, 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.
