The description of a LensRomantic test is here. These comparisons are for collectors or tech-enthusiasts. Photographers may go directly to a lens review.

Minolta New-MD 100mm F2.5 is one of the best-balanced portrait lenses – the ideal combination of focal distance, aperture, and IQ with weight and size. It was forgotten for some period, but today the lens is becoming popular again, and it is harder and harder to find it.

Final conclusion

I do not see any differences in sharpness, which are worth mentioning.

There is just one note for F2.5 only: if to use a microscope, you may see slightly strange behavior. In the center, the sharpness is the same for both lenses. But at the same time, the first copy is slightly better in the middle, and the second is slightly better in the corners. But, as I said, I do not think that this can be noticed when photographing. BTW: such behavior isn’t often but can be seen with other lenses, I’ll mark it if find another pair.
