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:

Antispam measure, image links for the first post of a new user don't work. You'll be fine now. Smile

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):
