Nikon's Ai-S fast wide — the manual-focus 35mm f/1.4 for the F mount, long-run low-light prime.
The Ai-S Nikkor 35mm f/1.4 is the Ai-S revision of Nikon's fast wide, introduced in the early 1980s and produced for a very long time. It brought full compatibility with the program bodies of the era while continuing the fast 35mm f/1.4 line, and it remained in Nikon's catalogue for decades as a manual-focus option.
This is a manual-focus Nikon F lens with a maximum aperture of f/1.4 and a fixed 35mm focal length, built to the Ai-S standard with its standardised aperture actuation. It is a fast retrofocus wide operating with normal reflex viewing. Only verified figures are stated; internal construction details are omitted rather than guessed.
Wide open the lens gives the glow, soft corners and coma characteristic of fast vintage wides, tightening and gaining contrast on stopping down. This rendering makes it a favourite for atmospheric night and low-light work. It suits reportage, street and available-light photography where both speed and look matter.
On the used market the Ai-S 35mm f/1.4 is sought after and holds strong value thanks to its long run and rendering, popular with both film and mirrorless users. Inspect the elements for haze and fungus, check coatings for marks, confirm smooth Ai-S aperture action, and verify the coupling ridges. It adapts cleanly to mirrorless where its character is well liked.
