Summicron 90/2 looks like 5 element Takumar?



Nope. Canon Tele lens patented in 1960 by the great Jiro Mukai, see here: http://www.google.com/patents?vid=USPAT3066575&id=jMBjAAAAEBAJ&pg=PP1&dq=jiro-mukai#v=onepage&q&f=false



This is quite interesting because it prevented Nikon 18 years bringing a short 85/1.8 to the market. They kept with a large Gaussian 85/1.8, or the Sonnarish 105/2.5. Then they took nearly the same formular. (Nikon F AI/AIS 85/2 1977-1995) (alike focussing helicoids, Nikon makes things reversed here...)


The Takumar 85/1.8(1.9)

was a "classic" Ernostar design, retrait from a Sonnar type. Not bad, since this design is still widely spread. But optical correction of the Canon was superior by a wide margin.

BTW, in the main diagram the Canon RF 50/1.5 is missing among the 7 elements Sonnars.

Nikkor 50/2 (H, H.C, K and AI) to add att Biotar/Xenon list.

A very common lens on the s-h market and an cheap one to. F-mount makes it usable on a lot of things using 24x36 or smaler.


Bad link or am I doing something wrong? Test this:

Beautiful chunky cemented elements that give lenses the edge: Pentacon (Meyer) 2.8/135mm and Jupiter 4/200mm.

It seems to me both Meyer / Pentacon Orestor 2.8/100mm and 2.8/135mm are still listed as Primoplan designs with wrong scheme.
Both lenses have nearly the same design (135mm in my previous post):

Does anyone know what optical scheme has the Color Lanthar 50 2.8 of the Voigtlander Vitoret DR?
Thank you very much.

I stumbled across this today having been looking for the schematics for Rollei Planar 50/1.8 and Schneider Sl-Xenon 50/1.8.
This site is just awesome: wonderful work NoX, and everyone else. Thank you.

Maybe a bit too many to add to the "Sonnar Simplified 4 elements" lens diagram but here's a list I made based on diagrams from several sources.
IMHO, it would honor the inventor of the Gundlach Ultrastigmatic more if that design group gets the name "Enhanced Ultrastigmatic" which in fact it is more related to, including the versions with a cemented pair (extra element) at the rear.

Quote from the Vademecum:
Ultrastigmat (1916 ) f1.9 40, 50, 75mm for 35mm movie. The layout is roughly Ernostar-4,
but is more compact and anti-dates it. The Brit. Pat. covers 2 types with different separations to the
glasses 1 and 2, and also considers a cemented pair for glass 4.(Brit. Pat. 187082/1921 to Charles.C. Minor.
This claims coverage of 80°, and may be the first use of the layout and a Landmark (Layout Gun004).

This discussion on the Hugo Hahn lens designs for Optische Werke Rüdersdorf A.G. (Rüo Optik) lenses
should be considered too. The Soviet Kaleinar has its origins in that work done. All running parallel in time to the early Ernostar
design period if not earlier.

+1 - thanks. It's otherwise hard to find a single place where this fundamental information is gathered.
