The 2/25 seems to be another super-sharp wide angle from Zeiss.

Well it would be easy to think so. But it's debateable. In 1931 a British Patent was granted to H.W. Lee & Kapella Ltd (Taylor, Taylor & Hobson) describing a type of lens which is now known as a retrofocus lens. The role of this type of lens in the Technicolor process is described here by Cooke Optics Ltd. (yes the name Cooke is related to the Cooke triplet).
The Zeiss article did mention the Technicolor process. A specific reference to Horace Lee, and possibly others (the patent makes some reference to earlier work) might not have been inappropriate. _________________ John |
