Nikon Nikkor 24mm f/2.8 AI-s

Wide AngleMount: Nikon F24mmf/2.8 – f/22
Introduced: 1981

Nikkor 24mm f/2.8 AI-S is Nikon's classic wide-angle prime in the AI-S manual-focus lineup — designed with a 9-element Distagon-derived optical formula optimized for landscape, architectural, and environmental portraiture work. The 24mm focal length on 35mm sits between "moderate wide" (28mm) and "ultra-wide" (20mm); it provides the widest perspective most photographers find natural without aggressive distortion.

Key features

  • 24mm focal length on 35mm full-frame
  • f/2.8 maximum aperture — fast for a wide-angle prime
  • Floating element design — improved corner sharpness at close focus distances
  • CRC (Close-Range Correction) — distinctive Nikon AI-S design element
  • 52mm filter thread — common across Nikon AI-S primes for filter-set compatibility
  • AI-S aperture coupling — works on all AI/AI-S/F3/F6/D-series digital bodies
