Nikon's generic 50mm f/1.4 listing — likely a pre-AI, AI, or AI-S version without specific designation.
The Nikon Nikkor 50mm f/1.4 without specific Ai/Ai-S/Pre-Ai designation may refer to any version of Nikon's manual-focus 50mm f/1.4 — check for specific coupling type. Multiple versions exist from 1970s onwards.
Same proven 50mm f/1.4 Nikkor formula across all versions — sharp from f/2.8 with characterful rendering. The specific version (Pre-Ai, Ai, or Ai-S) determines compatibility and should be verified on used copies.
Nikon F mount with 52mm filter thread. Check for specific version — Pre-Ai can damage some bodies, Ai provides basic metering, Ai-S adds programmed auto. Check oil on aperture blades — common on all versions.
Available used at budget to mid-range prices depending on version. Verify the specific coupling type before purchasing. See IDs 817 (Ai-S), 1761 (Ai), and 1947 (Pre-Ai) for version-specific details.
