    Overview

    The Nikkor 20mm f/2.8D is a compact, well-built wide-angle lens praised for its portability and solid construction. Optical strengths include good sharpness wide open and swift autofocus, though slight light falloff at f/2.8 is noted. Weaknesses include a narrow focus ring with short throw, making manual focusing tricky, and a poorly marked DOF scale. It suits photographers needing a lightweight, durable wide-angle for hiking or general use, but not those seeking the ultimate sharpness among Nikon 20mm options.
