Uncool??? UNCOOL??? Ain't NO Way!!!
Anyway, The Zunow(lens Q on attachment) is very rare. Nikon also made a screw mount version of the 5cm F1.1 Nikkor(lens c). Both of these are 9-element optics. Canon started using a high-index of refraction glass in the late 50's and used 7 elements in the 50mm f1.2 and 50mm f0.95 (lens T). Both are remarkable lenses. So much, that Nikon used the same formula for the famous 50mm f1.4 "Olympic lens" that was re-issued in 2000 with the S3-2000. So if you want the fastest lens that was so good that Nikon copied the formula, ya gots'a get ya'self a Canon 7!
Now that is cool.
Formulas for "normal lenses", Neblette, "Photographic Lenses", 1965.

way, that's COOL indeed. First time I see the Zunow formula. Great complication. The Canon 0.95-50 can also be found at Canon Museum...

Where did you find that one? Do they cover the '40s and '30s?
Most of these are in the 1965 edition of "Photographic Lenses" by Neblette. He sorts them by focal length. The later '73 edition elimated over 1/2 of the lenses shown in the prior edition, but had more to say about lens design in general.

Don't know where I found it, somewhere on the web. I only have one book about camera optics (Das Auge meiner Kamera, H.Naumann, ~1949). It explains optical errors and how to correct in detail and has a lot of early lens design up to that, but no newer stuff except a diagram of the Biotar 1.5/75 and Nokton. No dedicated wideangle or high speed stuff.
Seems I have to look for an older version of the Neblette book ;-) ..oops, just found it at amazon.com for 9.95 USD...
