The Planar lens icon
Tessar, Planar, Sonnar, Biogon and Distagon – they are all examples of famous ZEISS lens names. In our series of CLN articles, we introduce where our lens names come from and which special properties these lenses have.
We dedicate today’s installment to the Planar lens.
As Paul Rudolph registered the Planar lens from Carl Zeiss in Jena for patent in 1896, he was clearly unaware that this lens would write photographic history in the following century. Since then, the Planar lens has been installed in countless variations by a large number of manufacturers, with a steady flow of designs using new calculations constantly entering today’s market. Up until today, it has served as the foundation for high-performance lenses with impressive color correction, speed, field flattening and distortion correction.
Join Dr. Hubert Nasse, Senior Scientist at the Carl Zeiss Camera Lens Division, for a journey of discover of the properties of the Planar lens. His article will tell you how the Planar got its name and why it only enjoyed marginal success during its early years despite its outstanding new properties. Dr. Nasse also gets to the bottom of many technical achievements: for example, what meniscus-shaped, bonded elements are capable of, how the Planar 0,7/50 became world famous or the connection between the S-Planar and Makro-Planar.
