What actually differs

  • The Olympus OM-System Zuiko Auto-S 55mm f/1.2 is 0.4 stops faster: f/1.2 against f/1.4.
  • The Minolta MC Rokkor-PF 58mm f/1.4 is cheaper. Typical used value is $130 against $500, a gap of $370 (roughly 3.8x). Ranges: $70 to $260 versus $300 to $900.
  • The Minolta MC Rokkor-PF 58mm f/1.4 is longer at 58mm against 55mm, a 3mm difference that tightens framing slightly and increases background magnification.
  • The Minolta MC Rokkor-PF 58mm f/1.4 is the older design; production began around 1958 against 1972 for the Olympus OM-System Zuiko Auto-S 55mm f/1.2 (1958-1970s versus 1972-1984).
  • They use different mounts, Minolta SR (MC) and Olympus OM, so each needs its own adapter. Both reach infinity on mirrorless bodies with a plain mechanical adapter.
  • Construction differs: 6 elements in 5 groups for the Minolta MC Rokkor-PF 58mm f/1.4, 7 elements in 6 groups for the Olympus OM-System Zuiko Auto-S 55mm f/1.2.

Which one to buy

Choose the Minolta MC Rokkor-PF 58mm f/1.4 for the $370 lower typical price. Choose the Olympus OM-System Zuiko Auto-S 55mm f/1.2 for the 0.4 stops of extra speed. Rendering differs too: read the character notes below, because speed and price are the only advantages the catalog data can settle.

Minimum focus distance, weight, and measured sharpness are not in the catalog, so this comparison does not claim anything about them.
