I just acquired second 50mm and have no chance to compare them on digital, film only and that's just to say is not very convenient. So surely somebody on this forum had both, Attila probably ?
So which one is better?
1. Minolta MD 50mm F1.7 , on the left
2. Minolta MC Rokkor-PF 50mm F1.7, on the right
What PF stands for? Which one should I keep?

PF is the code for how many elements and groups. I had an older version of the PF you have and it was a superb lens, one of the better 50s for SR I have tried. I expect these two are the same optically just updated in materials used for the barrel and coatings. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

P = 5 groups, F = 6 elements, and so has the MD, so it's probably true. _________________ My Flickr photostream: http://www.flickr.com/photos/chantalrene/

The left one has a tab for X-600, I think that is the lastest MD 50 1.7 from Minolta, but I could be wrong, since I have 2 different 50 1.7 with the tab .
By the colour and sharpness, I found out that my MC lenses render color more beautiful than plain MD lenses. The new coating from plain MD lenses, I think it has more CA and not as sharp as double coat in MC. |

I've never physically compared the two to see if they are optically the same, but the construction is very different.
The MC is built in the traditional way, with lens elements and locking rings. The MD has groups that are molded together with plastic. What this means is that if there is fungus on an MC, you can completely disassemble and clean those elements. But with the MD, if the fungus is between the elements in a group, you are out of luck!!
Not for the F1.7, but here is a comparison of the MC & MD F1.4:

Now, another MD 50mm popped my mind.... and i do have it, sitting on an un-used Minolta X-300.
It's the 50mm f/2.0 version. I looked up the build (6/5), and it is the same as the f/1.7 versions. Now i wonder: why did they make another, and slower, version of the 50??
This is a very nice list b.t.w. : http://minolta.eazypix.de/lenses/body_li.html
Anybody ever compared it to an f/1.7 version? _________________ My Flickr photostream: http://www.flickr.com/photos/chantalrene/

50 f2 is one of the most underrated lenses. It is like the Minolta 28 3.5 vs 28 2.8, people tend to like more fast lens and forget how good slow lens is. The reason I think is cost. Minolta in 1980s want to sell more to common people, so cost is critical. They changed from 55mm filter size to 49mm to reduce production cost, and it helps to reduce selling cost too.
50 f2 is my first lens of my life, it is very good.

The md 50/1,7 Is the best of all 1,7 normals of minolta. More contrast and redolution power than previous ones.
Generaly, the md has more contrast than the mc versions.
Not always have more resolution power
The plain md is better than the md rokkor. The mc should be better than the last. |

any chance that you could compare them wide open, at 2.8 and 5.6 let's say and post results? That would help a lot. Please pretty please _________________ http://www.flickr.com/photos/34787419@N08/

Well yes, that is what i was thinking about doing, and then compare all 3, so i'd take the 50 f/2.0 and test it as well, i have never used it!
I need some time to do this... so it will most probably have to wait untill somewhere next week..... _________________ My Flickr photostream: http://www.flickr.com/photos/chantalrene/
