Thanks Pau. Should be visible now. BTW, the lux is older than the Summicron v4. One might argue that both Nokton and Summicron v4 designs are derived from the 35 Summilux.
I would love to see a reference about the Nokton lead contents, and it changing over time.
Possible. Check Puts' "Leica M-Lenses: Their Souls and Their Secrets". The basic element/group
configuration is identical to your reference (its first computation?) above.
In any case: do we have a Nokton/lead reference, please ?
I´m interested in the Lead reference too. From what I understand, the tabbed 50mm Summicron and the current 50 with built-in lens hood, have the same lens cut - but different glass type and MC.

Has to be: Summicron 35/2 pre-ASPH! The Summilux 35 pre-ASPH was a 8-element design, so is the new CV Nokton 35/1.4. The lens diagram looks quite equal - oni soit que mal y pense ...
He also has a diagram of the v4 cron. Seems like he uses the identical diagram for both, Summilux and Summicron, so maybe I based myself on an error in his book.
