Nikon's Ai fast wide — the manual-focus 35mm f/1.4 for the F mount, low-light rendering favourite.
The Ai Nikkor 35mm f/1.4 is the Automatic Indexing version of Nikon's fast wide, released in 1977 as the Nikkor line adopted Ai metering. It carried the fast 35mm f/1.4 line forward with open-aperture metering on Ai bodies, remaining a favourite among available-light photographers.
This is a manual-focus Nikon F lens with a maximum aperture of f/1.4 and a fixed 35mm focal length, carrying the Ai aperture-indexing ridge for open-aperture metering. It is a fast retrofocus wide operating with normal reflex viewing. Only verified figures are stated; construction details are omitted rather than guessed.
Wide open it shows the characteristic glow, soft edges and coma of a fast vintage wide, which sharpens and gains contrast as it stops down. This rendering is sought for atmospheric low-light and night work. It suits reportage, street and available-light photography where the bright aperture and its look are both wanted.
On the used market the Ai 35mm f/1.4 is popular and holds solid value, sought by film shooters and mirrorless users for its rendering. Inspect for haze, fungus and coating marks, confirm the aperture blades are dry and snappy, and verify the Ai coupling. It adapts cleanly to mirrorless where the wide-open character is prized.
