What actually differs
- Both open to f/1.4, so neither has a speed advantage.
- The Canon FD 50mm f/1.4 S.S.C. is cheaper. Typical used value is $100 against $110, a gap of $10. Ranges: $55 to $200 versus $60 to $220.
- Both are 50mm lenses, so framing is identical on the same sensor.
- The Nikon Nikkor-S Auto 50mm f/1.4 (pre-AI) is the older design; production began around 1962 against 1971 for the Canon FD 50mm f/1.4 S.S.C. (1962-1974 versus 1971-1990s).
- They use different mounts, Canon FD and Nikon F (pre-AI), so each needs its own adapter. Both reach infinity on mirrorless bodies with a plain mechanical adapter.
- Construction differs: 7 elements in 6 groups for the Canon FD 50mm f/1.4 S.S.C., 7 elements in 5 groups for the Nikon Nikkor-S Auto 50mm f/1.4 (pre-AI).
Which one to buy
On the catalog data the Canon FD 50mm f/1.4 S.S.C. wins on the $10 lower typical price, and the Nikon Nikkor-S Auto 50mm f/1.4 (pre-AI) gives up nothing measurable in return except its own rendering, described below. Condition and variant matter more than the spec sheet at these prices.
Minimum focus distance, weight, and measured sharpness are not in the catalog, so this comparison does not claim anything about them.
