Camera used Sony A7R2
Lenses in this test:
Auto Mamiya/Sekor 50/1.8
Auto Mamiya/Sekor 50/2
Fujinon 55/1.8
Mamiya EF 50/1.4
Mamiya EF 50/1.7
Mamiya SX 55/1.8
Minolta Rokkor-PG MC 58/1.2
SMC Pentax 50/1.4
Super Takumar 55/1.8
Yashica ML 50/1.4
First the fast lenses wide open:

And the 100% crops:

The Rokkor, being the fastest (and longest focal length) lens, does the best job of eliminating the background. On the 100% crops, the Rokkor is the softest wide open, but OK this is f/1.2. The other three lenses quite similar; I think the Mamiya EF 50/1.4 has the best contrast.
Then, f/1.7& f/1.8 lenses wide open:

The Auto Mamiya/Sekor 50/1.8 has cooler colors than the other lenses.
100% crops:

Sharpest of these lenses wide open: the Auto Mamiya/Sekor 50/1.8 and Mamiya EF 50/1.7, the latter showing most contrast.
Comparison @ f/2:

The Auto Mamiya/Sekor 50/1.8 has the coolest colors. It's also noticeably cooler than the Auto Mamiya/Sekor 50/2. It seems these two lenses are different; or they use different glass?
Best sharpness from the Auto Mamiya/Sekor 50/1.8 and Mamiya EF 50/1.7. The difference in contrast between these two, became much smaller at this aperture.
Comparison @ f/2.8:

In terms of detail/contrast the Mamiya lenses do all pretty good, as well as the SMC Pentax 50/1.4 and Yashica ML 50/1.4.
Comparison @ f/4:

It seems the Auto Mamiya/Sekor shows some more unsharpness now, possibly caused by the wind. Clearest image IMO: Auto Mamiya/Sekor 50/2, Mamiya EF 50/1.7, Mamiya SX 55/1.7 and SMC Pentax 50/1.4.
Comparison @ f/5.6:

Detail resolution very good from all lenses. Best sharpness/clearness/contrast the Mamiya 50/1.7 IMO.
Real world relevance is debatable, but IMO the Mamiya EF 50/1.7 is the winner of this test. At f/1.7 it's still fast enough for nice subject isolation, and it's quite sharp and contrasty at any aperture.
A while ago I did another standard lens comparison, containing a lot of other lenses, and the Mamiya EF 50/1.7 was the winner there as well. Kind of an unknown lens to many I guess, but just a very good performer.
I was also pleasantly surprised by the performance Auto Mamiya/Sekor 50/1.8, although I would make the colors a bit warmer in PP. |

I've got the revuenon Ef 1.4 versión, Wich might be the same as mamiya. Is a very light and sharp lens, posible the first center crop of 1.4 might be focused a little bit closer than other lenses , as the two black dots in the left side are more visible . It's not easy to do all these tests in real world , but in this case ,they are all capable lenses. Another important issue would be the cost of the adapter and the availability for each one of us, not last the price and quality . Mamiya maybe is the lightest one because it's got more plastic than the others. |

Yeah probably the same lens. I have the Revuenon version of the Mamiya E 28/2.8.
The Mamiya EF 50/1.4 is probably my favorite fast standard lens. |

Yeah, the E / EF's are interesting lenses. And you can build a nice compact set from them for example E 28/2.8, EF 50/1.7, E 135/3.5, all good performers. |

I think I like the Pentax colours best. It looks warmer than the rest, but when I took white balance of the back of the chair that was among the cooler ones. _________________ pentaxian |

Interesting finding. I checked that, and you're right. When I check with the color pipet on the wooden fence door though, the Pentax has the highest red to blue ratio by quite a margin. The chair is actually light blue. I suspect that the high contrast Pentax, despite having warmer colors, still lets through more of the actual color (blue) than some lower contrast lenses which have a less saturated reproduction. |
