Infinity comparison between the Minolta AF 50/2.8 macro (3 floating groups optical system) vs the rather simple Yashica ML 55/2.8 macro. Camera used: Sony A7RII @ ISO 100. 100% crops.

I must say I didn't expect these results from the Yashica ML, as it is supposed not to be great at infinity. Wide open, I think the Minolta is slightly better in the center. At all other apertures, I think center performance of both lenses is pretty much equal. In the corners however, the Yashica obliterates the Minolta. In fact, I think the Yashica is my best performing lens in this regard, in this focal range, with very respectable results already wide open. At f/5.6 the corners are almost perfect on the A7RII sensor, getting even better at f/8 and f/11. Great surprise! |

I would prefer the Yashica here. There is a pleasant glow wide open that can be put to effect. If you don't want it you can stop down. _________________ pentaxian |

Yes, plus You could probably get rid of it in PP pretty easily. |

Would be interesting to compare the Yashica to the Nikkor ai(s) 55/2.8 macro. Unfortunately I don’t have that one anymore. |

The 2.8 micro is excellent ,but I don't find it very easy to use for landscapes , probably because mine is a bit wobbling . |

These are both macro lenses; corner performance at macro magnifications vs. use at infinity will be a trade-off, even when using floating focus.
The difference in corner performance of the Minolta vs Yashica here may simply reflect a difference in philosophy between the designers, in as far as how much to optimise for macro performance but also still allow for acceptable infinity performance.
A comparison at 1:1 magnification ratio (and higher when used on bellows) may reveal more. _________________ Mark

I don't think the Minolta is bad at infinity; it's comparable to the MD 50/2 I found out before. But the Yashica is just incredible.
I will do a comparison soon at macro magnification. |
