John, the ghosts look pretty!
Yes agree. Unusual set of ghosts.
Actually the lens is pretty flare resistant. But the construction with 17 glass parts is special
Marco Cavina analyzed this lens:
"https://translate.google.nl/translate?hl=en&sl=it&u=https://www.nital.it/nikkor-historical/35-200mm.php&prev=search "In this diagram all the parameters related to the optical scheme are present: refraction and dispersion of the glasses, radii of curvature of the lenses, thicknesses and spaces on the axis, variable distances with the flotations. The optical scheme of the Nikkor 35-200mm is based on four groups of main lenses, all mobile, which involves four variable spacings during the focal variation and focusing: spaces D5, D13, D19 and the retrofocal distance Bf; the focal length of the lens is 36.12 - 193.96mm and its optic core is an amazing arsenal of special optical glasses, to the point that on 17 lenses only 5 cone were made with optical glasses with "normal" characteristics:"
"they are above all present two low dispersion glasses of the Phosphor-Krown type and proprietary formulation (L2 - L10), with Abbe number exceeding 70;"
"it is interesting to know that, in the original project by Tomowaki Takahashi, inventor of the scheme, the second lens was made of ED glass (even lower dispersion, with Abbe vD = 82.6 instead of 70.1), a further refinement it was renounced by setting production to avoid further burdening costs."
"There are also four Short-Flint glasses with high-very high refraction and high dispersion (L1 - L5 - L8 - L11), one of which refers to the Schott SF6 and the other three to a Nikon proprietary glass much used by its designers and characterized from a refractive index of 1,861, a value outperformed by the impressive Lanthanum Short-Flint in position L4, a glass with very high refraction (even higher than 1.9) and proportionally reduced dispersion with respect to this refractive value (vD = 35,8): as a reference, they are values that bring together those of the famous glass "Leica Noctilux" ..."
