The 20mm f/2.8D delivers a 94-degree ultrawide view with edge-to-edge sharpness and Nikon’s Super Integrated Coating to suppress flare, all in a lightweight 162g build. Its Close Range Correction system enables distortion-free detail shots as close as 0.85 feet, adding uncommon close-focus versatility for a wide prime. This lens best suits architecture and real estate photographers who need a compact, fast ultrawide for interiors and detailed work, though landscape-specific scoring lags notably.
