Lens-making is an art--Nikon artisans craft Nikkor optics from the finest materials, taking pride in adding their intellect and technique to bring the world's finest lenses to life. They push the leading edge of lens-making in their effort to provide the "glass" that makes the world's greatest pictures. AF Nikkor lenses work with Nikon SLRs for optimal performance, even the very latest. The Nikon 20mm f2.8D AF Wide-Angle Nikkor is compact ultra-wide-angle lens constructed with superb optical design for architecture, wedding and landscape photography. It features 94-degree (70-degree with Nikon DX format) picture coverage with edge-to-edge sharpness. The Close Range Correction (CRC) system provides high performance at both near and far focusing distances, for distortion-free pictures as close as 0.85 feet.
