A fresh perspective
Capture a new angle on life with the AF Nikkor 20mm F/2.8D lens. It's a versatile ultra-wide angle lens that's great for general photography. At f/2.8, it's a super-fast lens that captures beautiful pictures. The Close-Range Correction (CRC) system provides high performance at both near and far focusing distances. Squeeze more into your images with this quality Nikkor lens!
Nikon Super Integrated Coating
To enhance the performance of its optical lens elements, Nikon employs an exclusive multilayer lens coating that helps reduce ghost and flare to a negligible level. Nikon Super Integrated Coating achieves a number of objectives, including minimized reflection in the wider wavelength range and superior color balance and reproduction. Nikon's multilayer coating process is tailored to the design of each particular lens. The number of coatings applied to each lens element is carefully calculated to match the lens type and glass used, and also to assure the uniform color balance that characterizes Nikkor lenses. This results in lenses that meet much higher standards than the rest of the industry.
Close-Range Correction system
The Close-Range Correction (CRC) system is one of Nikon's most important focusing innovations, for it provides superior picture quality at close focusing distances and increases the focusing range. With CRC, the lens elements are configured in a "floating element" design wherein each lens group moves independently to achieve focusing. This ensures superior lens performance even when shooting at close distances.
Distance information
The 20mm Nikkor 20mm f/2.8D lens is a D-type lens. That means it relays subject-to-camera distance information to AF Nikon camera bodies. This then makes possible advances like 3D Matrix Metering and 3D multi-sensor balanced fill-flash. Note: D-type Nikkor lenses provide distance information to the following cameras: Auto exposure; F6, F5, F100, F90X, F80, F75, F70, F65, F60, F55, F50, Pronea S, Promea 600i, D2 series, D1 series, D100, and D70s/D70. Flash control; F6, F5, F100, F90X, F80, F75, D2 series, D1 series, D100, and D70s/D70.
