N90

N90 is a designation used in various contexts. The most widely known reference is the Nikon N90, a 35mm film single-lens reflex camera produced by Nikon in the 1990s. In some markets the camera was marketed under the F90 name, and it was later succeeded by the N90S. The Nikon N90 was noted for its automatic exposure modes, compatibility with Nikon F-m lenses, and ergonomic design.

Beyond photography, N90 is used as an alphanumeric route designation in multiple countries to label national or regional highways; the precise alignment and extent of the N90 route vary by country.

Additionally, N90 can appear as a model or part number in other product lines, but such uses are heterogeneous and context-specific.
