Carl Zeiss vs Minolta 28mm comparison – final conclusion:

Carl Zeiss C/Y 28mm f/2.8 vs. Minolta MD 28mm f/2.0

Minolta has a more advanced scheme and one-stop faster – this battle is not fair and Minolta won easily on the short distance:

  • Center – Both lenses are the same in this position
  • Middle – Zeiss shows better results in the middle position at F2.8, but from F4 up to the end both are the same
  • Corner -Minolta is better at any aperture

Note: I am very upset, but… unfortunately, the long-distance test was ruined. This happens (rarely) – several takes were spoiled at one time. When this became known, I already didn’t have a lens. That’s why I can demonstrate only a test at a short distance. For myself, I can conclude which lens is better on the long-distance – based on tests between Zeiss and Minolta 28/3.5 and also between Minolta 28/3.5 and Minolta 28/2.0 – any of readers can do it of course too. I just avoid posting conclusions here because I can not attach simply understandable diagrams.

Independently of the fact that this battle is fair, it was very easy to predict who would be a winner because the Minolta 28mm 1:2.8 with 7 elements in 7 groups optical design is the weakest 28mm Minolta’s lens from MD III era.

This is another unfair battle, just now Zeiss has a 2/3 stops advantage. Zeiss is the winner – no doubts, both lenses give a similar IQ at F8.0. Yes, I always recommend 28mm Minolta with F3.5 as an economy wide-angle lens, and yes – I consider that Zeiss is worth its money too.
