Nikon AF NIKKOR 20mm f/2.8 D Autofocus Lens Review

The Nikon AF NIKKOR 20mm f/2.8 D is a full-frame ultrawide prime that has been part of Nikon's F-mount lineup for decades. Its 20mm focal length makes it a versatile option for landscape, architecture, and environmental portraiture, while the f/2.8 maximum aperture provides reasonable speed for low-light shooting and selective focus control. This D-series lens requires a camera body with a built-in focus motor to autofocus, so it won't AF on entry-level Nikon DSLRs like the D3000 or D5000 series, though manual focus remains available. At $177 MSRP for used copies in excellent condition, it sits in the budget-friendly zone for a full-frame ultrawide, making it an accessible entry point for shooters looking to expand their wide-angle toolkit without investing in newer G or Z-mount glass. Build quality is typical of Nikon's older AF-D primes, with a metal mount and straightforward construction that has proven durable over time.
