yes, i saw that a couple of months ago
finished overhauling. surprisingly, it is an easy lens to disassemble to it's bare parts
(scotch tape, if you see it)
i got rid of some of the junk inside by blowing them away but when i closed it, i reintroduced new junk! now there are a little bit more specs than when i started! 面倒くさい!
the weird feature of this lens is the 2x helicoid keys and the unusual helicoid by nikkor standards. the central helicoid is 2x threaded
i guess the 50mm f/1.2 is the same.
wide open, my 50 1.2 is sharper than my noct. my 50 1.2 is exceptionally good even when compared to most of what's available out there because i forced nikon to make it that way by being annoying and persuasive
noct has no CA wide open at infinity wide-open.
still pretty sharp. HS-7 is a must
