Has anyone seen optical diagrams for the original, SL lens series?
The new SL2 have optical diagrams on the cosina site. Looking at the old 2003-era cosina site 9on the internet archive) showed some Japanese text which did not seem to say anything about the optical arrangement, and all the images were not archived.
I have the 90mm apo-lanthar, in Nikon AIS mount, and am curious to know about the optical arrangement. But details seem scarce. I checked the manual in the box, no information there.
(I also have the SL2 40mm ultron. Love both these lenses).
