Minolta MC Rokkor PF 50mm 1:1.7 vs Yashica Lens ML 50mm 1:1.9 – final conclusion

Everything can be seen in the diagram. Both lenses start to work roughly the same at F5.6, so the main battle takes place at open apertures and at F2.8-4.0.

In detail, it looks like this:

  • Open (1.7-1.9) – Minolta is slightly worse than Yashika in the middle of the frame and noticeably inferior in the corners
  • F2.8 – everything is the other way around, Minolta is noticeably better in the middle of the frame, but still loses in the corners
  • F4.0 – Yashika wins slightly in the corners.

Yashika had a good chance of winning, but at F2.8 the difference in the middle of the frame is so much in favor of the Minolta that even Yashika’s improvement at slower apertures doesn’t seem more important. Moreover, we are talking about 50mm lenses – apertures close to open and sharpness in the area of the “golden ratio” are important for us.

I have an idea – I am declaring a draw. But Minolta fans may think that Rokkor won, and Yashika’s fans that Yashika won.
