CRC (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. The CRC system is used in fisheye, wide-angle, micro and selected medium telephoto NIKKOR lenses.
Silent Wave Motor
AF-S NIKKOR lenses feature Nikon’s Silent Wave Motor (SWM). This technology converts “traveling waves” into rotational energy to focus the optics. This enables high-speed autofocusing that's extremely accurate and super quiet.
M/A
Select NIKKOR lenses have a focusing mode which allows switching from automatic to manual focusing with virtually no lag time by simply turning the focusing ring on the lens. This makes it possible to seamlessly switch to fine manual focusing while looking through the viewfinder.
Super Integrated Coating
Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses.
