| AF-S | Aufo Focus Silent - An autofocus lens with a Silent wave, integrated, coreless focus motor (1996). Basically an update to AF-I. Some older bodies can't autofocus with them (N60, N8008) |
| D | Distance Information. Adds distance information to the data transmitted to the camera via chip. Distinguished by the D or G after the lens designation |
| ED | Extra Low Dispersion Glass. Enable the production of lenses that offer superior sharpness and color correction by minimizing chromatic aberration. |
| IF | Internal Focusing |
| ASP | Aspherical Elements. Aspherical lenses virtually eliminate the problem of coma and other types of lens aberration — even when used at the widest aperture. They are particularly useful in correcting the distortion in wideangle lenses. In addition, use of aspherical lenses contributes to a lighter and smaller lens design. |
| SIC | Super Integrated Coating, a multi-layer flare reduction coating, usually applied to the more complex zoom lenses. |
