I've heard these lenses are the same designs and actually, Minolta made the 24mm for Leica. Has anyone compared these? I have a Leica R lens kit and I want to add the 24mm to it, but the Minolta is significantly cheaper than the Leica version...

That is true. But only the MC and early MD Minolta's are the same, those with 9/7 construction and floating element. The final MDIII version of Minolta is an 8/8 construction.
They are indeed cheaper, but it will not fit you Leica camera.

The original optical design is from Minolta. Leitz built the lenses in Germany. So the Leitz/Leica-branded 24mm R-lenses are not made by Minolta. (according to Erwin Puts' Leica lens compendium) |

Quute from the Leica pocket book : "In the beginning Minolta supplied the glass elements and Leitz did the assembly. Later, when Minolta stopped production, Leica continued to produce the lens. "
So i guess it depends on how old your Leica 24mm is if the elements were produced by Minolta or Leitz.

Thanks for that, I'm actually adapting these lenses for EF so don't mind mixing mounts initially if the quality is the same. I'm guessing the coating differs though?

I already own 4 Leica R lenses, but I'm not blindly brand loyal so if I can get the same lens for 1/3rd of the price, I'm going to save the cash

Minolta film lenses can't be used on a EOS camera with simple adapter(the lens will not focus to infinity). The 24/2.8 does not perform well on a FF sensor if you corner performance is concerned.

I do not see that as a problem personally.... i use it on Sony A7.
See also : http://forum.mflenses.com/hexanon-2-8-24-vs-mc-w-rokkor-2-8-24-t74287,highlight,%2Brokkor.html
although not the best samples for corner performance..... (maybe last pic at f/4)
Cheers!

I have this lens and it's really a top performer. Strongly recommended.
Although only on APS-C camera this comparison might be interesting as well:
http://forum.mflenses.com/24mm-lens-comparison-minolta-pentax-tokina-t76783.html
However, with a Canon camera you are out of luck. This lens isn't adaptable without additional converter glass.

I've heard that the Olympus OM 24/2.8 is better than most competing lenses - it's certainly the same price or cheaper as the Minolta and I believe more compact. They also made an F2 variant. Since the FFD is much longer on the OM system, you can adapt to EF with a glassless adapter and maintain infinity focus! |

OK, thank you. You are absolutely right. The newer MD III version is much better, particularly in terms of corner performance.

Here is a very nice test report of the MD III lens:
https://photolenses.wordpress.com/2018/01/10/minolta-md-24mm-2-8/
However, I don't know anything about the Seagull sibling.

The Seagull 24/2.8 has 8e/7g.

They have similar scheme but:
The MDI have smaller lenses than the MC:
The same formula, yes. But the elements are not interchangeable between them.
The MDI's elements are smaller than the MC's ones.
So the lenses aren't the same.
They have different rendering, and this is the reality. |

Papasito,
This does not look right. From the tables, it seems that MC MD I and the first MD II are the same and that Minolta issued a 2nd MD II much lighter (215 versus 275 g) before launching the MD III 8/8. It remains to be seen whether the 9/7 lenses are not all the same with the latest MD II version being just a mechanically optimised version.
Artaphot does not differentiate between the various 9/7.

Minolta changed the barrel construction a few times, not the element's size. That would make it a completely different calculation if you ask me.
Any differences in rendering is due to the fact that they improved on coatings over the years.

like this:
This MD-I lens has its DOF scale on a tubular shape barrel
The early MD-II lens also had this exact same shape and weight
This MD-II lens has its DOF scale on a conical shape barrel
