It's been known for decades that funky bokeh can be pleasing for portraying the subject in away that some humans like to see, but saying that the Zeiss choices in aberrations make the images more "realistic" is just plain bull****.
And I have NO idea what this thread is doing in the Nikon forum. It belongs in the Alternative Gear forum where all the experts in micro-contrast hang out...

At the end of the day it's all about using the right lens for the job, and I won't hesitate to use my Sigma art lenses. The ability to get high quality images wide open is awesome, especially in low light. The engineer in me does find this very interesting though. I can also see the usefulness in understanding why similar lenses draw differently.
Go take a look at all the wonderful images in the manual focus thread. Older lens images look AMAZING, and do render quite different than modern glass. As far as the mysterious Micro contrast, you have to look at the fine detail, and not the bigger picture.
while you are looking for the micro contrast you do miss the real image and what it might actually be saying. you know the old forest for the trees thing.
I didn't bother to read the blog post since it seemed like a bunch of mostly drivel, but I will say that I do feel like old lenses definitely have a different feel and characteristic to them, a certain warmth and charm that I sometimes prefer over modern cutting edge glass that to me, have a somewhat clinical feeling at times. It's an entirely subjective thing that can't be described on technical terms, only emotional ones.
That may be how this blogger feels about Zeiss glass, and that's alright with me. Then again I havn't read the article, so ehhh.
Anyway, this is why my kit consists of lenses from the early 90s all the way to modern glass of the past few years. Sometimes I just want a certain look that only older. "lesser" glass would give me without having to do a bunch of editing.
I think the author caught some valid points. Main message is IMO to ask yourself if your really need all this newer/newest highly corrected glass. I can add from my own experience that newer is not always better - made this experience with the Leica 35/2 ASPH lens. Supposedly it is highly corrected by using the ASPH glass element for corner sharpness, but it has severe debits if used on a non-Leica based mirrorless camera. I returned this lens and got the predecessor version IV of this lens (pre-ASPH) - what a beauty! I am totally fine with its corner sharpness, and it works on different camera brands, too.
This whole 3D effect thing is something more subjective - likely the author relates to less corner sharpness bringing out focused (center) areas better. The nose examples can be also affected by the distance to the subject and the focus point.

This whole 3D-look thing is so subjective, and has gotten a bit misused and misunderstood in my opinion. A lot of the "3D-look" can be attributed to (gasp) good composition partnered with deliberate depth of field play (focal length, aperture used, distance to subject, distance to OOF background, distance to OOF foreground etc); the lens itself technically I feel has much less to do with that "look."
I've got the Zeiss 135/2 APO and it looks better than most other 135's due to the really good contrast and correction wide open. Stopped down I don't see a huge difference.
My Leica glass also has a "look" to it, but not sure it's better or worse.
In general I've found that Zeiss and Leica high end glass (there are some duds . . .) looks better at or near wide open just due to the better correction of the optics. Stopped down it's not clear to me they are all that different.
If the author of the cited web site had carefully take the same images with the same subject with different lenses and logically compared them I would find some value in it, but as it is it's a mess and not useful.
mystery or not, i don't know but thre is something about Zeiss lenses, i used 50mp and 21 2.8 and sold them because i can't use manual lenses effectively
I think it's a post from a guy without a technical knowledge of optics who's trying to express what he sees in new lenses vs older designs. And of course he's made a subjective decision that certain optics look better than others.
I have no idea what the real truth is, but I have to say that I've owned a handful of older, simpler designs that "suck" when put on the bench that under certain circumstances can create a look I can never seem to get from my modern "excellent" lenses. Whether that makes them better or worse is another story.
edit:
After poking around on this guy's site... it's not that I don't think he has a point about *some* lenses, but he doesn't seem particularly consistent in identifying lenses that display the attributes he thinks are there. In addition, there are very few photos of direct comparison, leading me to believe that the effect he's after is really more a result of a combination of things - light, subject/camera/bg distances, etc.
Then he goes completely off the rails in one article showing these exact same shots of a stuffed bunny next to a set of books, and I realized he's just wacking off and obsessing about the minutiae of lens performance in a different way than all the other people who are wacking off and obsessiong about the minutiae of lens performance.
I love beautiful buttery smooth bokeh just as much as the next guy. But I'm nearsighted and when I take my glasses off "the bokeh" is not very smooth. So what is "realism"? :P
Zeiss definitely has a look, as does Leica, but this article does little to explain it or any problem with modern lenses. I actually think there are more makers producing competitively great glass now than a couple decades ago with Sigma Art, better Canon Ls, the recent Fuji lineups, and even 'cheap' lenses like Samyang are better than just being sharp. And yeah, not ALL modern lenses are sharp, and they 'should' be sharp wide open, just mostly aren't...
Random noses and foreheads of different people in different lighting situations does little to express anything mystical fwiw.
i actually seem to generally prefer older flawed lenses to modern perfect lenses but this blog post is mostly nonsense to me.

It's like "the Mandler Look" You have to really be grasping for commonalties, as humans often do, making stories out of unrelated things.
the mandler look also known as the "leica glow" is actually pretty well defined (unlike the "zeiss 3d look") – it's under corrected spherical aberration. it's a fairly obvious aberrations that shows up similarly in all of mandler's fast designs. mandler lenses typically need to be stopped down further to get rid of the glow than contemporary designs from other makers (usually around f/2.8 or smaller for the mandler summiluxes).

And even glasses on, your eyes never defocus enough to generate the kind of OOF areas you are in photography.
Focusing on my finger a few inches away from my face, the other side of the room is blurry, but barely - similar to 24mm at f/8? Maybe even smaller, considering how close.
