Rare fast Nikon 24mm f/2 wide-angle, one of the brightest manual focus wide-angles for astro and low-light work.
The Nikon Nikkor 24mm f/2.0 AI is a fast wide-angle prime from 1977 that provides an unusually bright f/2 aperture at 24mm — one of the fastest wide-angle lenses available for any SLR system. The fast aperture enables low-light wide-angle photography and creative depth-of-field control unusual at this focal length.
The f/2 aperture provides a full stop more light than the common f/2.8 24mm alternatives, offering a brighter viewfinder for precise manual focusing and the ability to create shallow depth of field even at wide-angle focal lengths. The optical design delivers sharp results with Nikon's clean colour rendering.
Build quality is premium Nikon AI with all-metal construction, smooth focusing helicoid, and the precise mechanical feel that characterises Nikon's finest manual focus lenses. The compact barrel balances well on Nikon F-mount bodies despite the fast aperture.
The Nikkor 24mm f/2 AI commands premium prices on the used market as one of the fastest manual focus wide-angle lenses ever produced. The extra stop over f/2.8 alternatives provides genuine creative and practical advantages for astrophotography, available light, and environmental portrait work.
