Too damn bad it is clearly engraved 'Goerz Hypergon' instead of 'Goerz Rectigon'.
Oh well.
Yes, I can read too. My issue with the auction isn't the name though, but the faulty description, and the fact that he doesn't care to amend it. Dollar signs in your eyes will do that.
There were
two hypergon lenses. One was the ultrawide lens with 130+ degrees coverage, made by Goerz Berlin and later by Zeiss (after they bought out Goerz Berlin in the 20's). A very valuable lens, and quite distinctive with it's bulging elements, having the appearance of two halves of a marble set into an aperture.
The other was made by Goerz USA, and is a rather different, much less exotic beastie. To quote directly from a 1959 Goerz USA catalogue: "Goerz Hypergon f22 or f32 fixed stop. A special lens for mapping, plotting and rectifying equipment, for military and industrial applications. Focal lengths 127mm, 135mm, 168mm. Coverage 90 degrees. Special sizes to order." Just like the Hypergon for auction.
As far as I am aware, Goerz USA never made or sold the ultrawide type Hypergon, only Goerz Berlin and Zeiss did.
I pointed this out to the seller, but like I said, he doesn't seem to care. I just thought I'd give a heads up to folks who might otherwise be duped.
