Distinguished by its impressively broad field of view and manual focus operation, the NIKKOR 20mm f/2.8 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, Close Range Correction helps to ensure consistent image quality and accurate rendering throughout the focusing range. Additionally, a seven-blade diaphragm contributes to a pleasing bokeh quality.
