No surprise with this lens - it's a good one, as plenty of people before me already pointed out. Consequently also not among the more affordable ones, but not (yet) too expensive either if you're patient. On aps-c it works great as a normal wide (36mm equivalent), so it could just as well stay on a camera forever. Mine is the 9/7 version in MD-II style with conical DOF scale and 55mm filter ring. The 8/8 MD-III with 49mm filter ring is supposed to be even better, but mine isn't bad either as far as I can see.

The lens itself:

Very good samples, Miran ! Like 1 small
#3 is especially great with large depth of field. The lens keeps the details very well.

Excellent photos.
When travelling I take this lens (with A 6000) as it is affordable. Otherwise I take the 20mm f 2.8 as it is a bit wider (eq 30mm FF).
Would be nice if somebody had compared them in terms of quality

Thank you. I have the 20mm too but sadly it's in 100% top condition so my conclusions can't be exactly definitive as a mint copy might be better. I will eventually make a direct comparison but having done just a quick side by side test I'd say the difference in image quality is clear and the advantage is well on the 24's side, at least when looking at my particular copies.

I've got one of these as well. A gem of the Rokkor lineup for sure!

I have the same version.

It's not the Leica copy.

Has the same 9/7 as the original MC 24 mm lens, but the MD has smaller elements than the MC.

I had both and dessamble the two for change elements among them, but I couldn't. The MD's ones were smaller.

The coating is good, better than the MC.

The from wide open to F/8 the corners are very soft and a lot of lateral CA.

At F/11 corners are almost OK, but CA no.

One more thing, I have one MD now, but I had five. I was looking for one very good. The best tha I found, it's with me.

And the five had some and strong lateral CA at the corner. Longitudinal too, obviously.

Central definition, colors and contrat are very, very good to me.

Yes, I still have to hunt down a newer 8/8. But they seem to be a little on the expensive side. Neutral

Everything that I have read about this lens says that the MC and the MD versions have the same optical scheme.
No wonder that coatings have changed with the time. Don't you think that simply the mechanical construction had changed , making impossible your cannibalization tries ?

I couldn't think that because I had some elements in my hands, and they were differents .

I do't know why is so difficult to undestand.

I never said that the scheme is different.

I only said what I saw with my own eyes, I never read this in magazine nor similars.

I saw that all the MD elements I had in my hands were smaller than the MC ones.

No more than this, no minus.

According to my experience with Sony A7 series and NEXes 5N/7,the MD3,8/8 isn't significantly superior compared to the previous 9/7 MC SI/MC/MD1 models,that I have.

It is just constructed optically in a different way.The major difference in the real life shooting is that the MD3 8/8 presents more even sharpness across the FF/APS-C frame ,at cost of lower resolution in the center and lower microcontrast all over stopped down.

The MD2 24/2.8 is the lens I have never tried.Mainly because having many similar copies,I was reluctant to buy another one.But first of all - I knew it is not a stellar lens.

Samples upon request - it just takes pretty long time before I can find them in my not so well organized files:-)

How does one tell if they have the 8/8 version or the older one? I have an MD, but that is as much as I know.

It is a Minolta not a Rokkor . Filter diameter is 49 mm .

Artaphot.ch ( Stevemark) is my source. You can see also that the front element is smaller and flatter.
