2. Evolved Design
• Advanced optical design: The latest optical design technology ensures high resolution and superb reproduction of point images while minimising chromatic aberration, enabling the photographer to deliver clear, well-defined images.
• Impressive clarity and accuracy: The adoption of Nano Crystal Coat effectively reduces ghost and flare for a clear depiction and crisp images.
• Quiet and portable: The AF-S NIKKOR 20mm f/1.8G ED is compatible with a wide range of 77mm screw-on filters and is designed with portability and quiet operation in mind. The compact and lightweight design ensures it is easy to carry to shoots. It also employs a Silent Wave Motor (SWM) for quiet yet smooth autofocus (AF) operation.
1 When used with a Nikon DX-format digital SLR camera, the effective angle of view is equivalent to that of a lens with a 30mm focal length in 35mm  format.
