Yes, twoNed, do you have Summilux AA in your collection?
Wonderful! What do you like about it?Yes, two

Wonderful! What do you like about it?Everything I like about this lens is unrelated to optics and imagery.
These are valid points.it was a difficult lens for leica to make
I was told there were only 2 or 3 people on the assembly
that could put it together at a high standard
quality control was very tight on it
so a replica - you can copy the optics I guess
2 aspherical surfaces
the Jupiter 12 3.5cm f2.8 is technically a copy of the prewar biogon by zeiss
but quality does vary on them quite a bit
at one point LLL - they were going to make a copy of the zeiss 15mm f8 hologon
a few ptrototypes were made - but that's as far as it got
There's one on eBay asking $750k, or something like that. Small fortune, indeed.I once owned a copy of the original Leica lens in silver chrome, which I'm sure would be worth a small fortune today!
So you admit it's just an ostentatious display of wealth?Everything I like about this lens is unrelated to optics and imagery.
Not at all.So you admit it's just an ostentatious display of wealth?
I guess we finally agree on something!
The differences in the intervening 35 years are massive. LLL are using moulded not hand ground elements. If they collimate them using modern equipment (and given how they are working now I am sure they will) and apply adequate QA/QC measured by modern methods, they will be better elements and more accurately assembled than lenses from the early 1990s, even from Leica. But not as good as a Leica lens from 2025. That’s how things go.it was a difficult lens for leica to make

See, this is the kind of esoteric photographic knowledge I've come to expect from RFF, apart from the skill and talent, the engaging discussion, the camaraderie and mutual upliftment, and the historical knowledge.The differences in the intervening 35 years are massive.

Great shot! I'll bite -- who is this?All of whom were trained by this guy., or trained by someone trained by this guy.

I don't totally believe that you are asking this in earnest.What’s the main selling point of this lens again?
He was an optical engineer who worked for, among others, Elcan, Optical Coating Laboratory International (OCLI) and Zeiss. He asked me not to publish his name. He died in 2024, a few days before he turned 94. He was a good friend of my father.Great shot! I'll bite -- who is this?
