It was here, in 1846, that Herr Zeiss began his workshop, making high quality magnifying glasses for the faculty of Jena University. From humble beginnings these Carl Zeiss Works grew into one of the largest and most prestigious optical companies in the world.

Carl Zeiss was born in Weimar, Thuringia States on, September 11, 1816. His father was plant manger of a turnery on Weimar Court. Carl attended school and finished the sixth form at the Weimar Gymnasium. Soon after, he apprenticed himself to Dr. Frederick Koerner who was investigating glass for telescope objectives. Upon completion of his apprenticeship, Carl Zeiss was employed briefly as an auditor at Jena University.

While in this position, Herr Zeiss began a study of the theory of lens manufacturing. Later Zeiss traveled for seven years visiting with glass and lens manufacturers in cities such as Stuttgart, Darmstadt, Wein, and Berlin. He made extensive notes on glass melts, materials, kiln temperatures and anything related to the manufacture of glass, microscopes and other optical instruments.

When he returned he attended Jena University where he studied chemistry and mathematics. Then in 1846 when Carl Zeiss was just 30 years old, he started his workshop at Neugasse along the gate street in Jena. The legend "Carl Zeiss" factory was established. Carl Zeiss' first products were magnifying glasses and simple microscopes produced by a group of 20 employees.

By tracing the history of Carl Zeiss, we find it becomes the history of photography. The Carl Zeiss Lenses are favored by a great number of photographers. For example, Ansel Adams (a photographer who develop the zone metering method) loved the Sonnar lens; he appreciated the importance of a visual image, that while the overall image may set the mood it is the subtle details, light, dark, shadow and form, that allow the soul to express itself. To realize this end, Carl Zeiss made daring challenges to the development and production of lenes, resulting in one after another masterpiece of optical engineering which will be forever engraved in this history of photography.

Protar - Carl Zeiss' first camera lens

Carl Zeiss' first camera lens was designed in 1890, by lens researchers named Paul Rudolph. This lens, meaning "the originator" overcame the most difficult barrier in lens design, that of making the distorted focused image appear flat. The theory used in this design, called "Rudolph's Principle", was later used as the basis of lens design.

Planer f3.6 - Now inheriting this name

Launched in 1896, this lens was considered a masterpiece of the no aberration lens and also design by Paul Rudolph. Actually, the Planer lens design is one of the most importance lens type design and the Planer design can be found in every manufacturer's 50mm lens.

Tessar f6.3

Launch in 1902. This lens type is regarding as " The Eagle Eye" which enthralled the world's photographers. Light, small, relatively high resolution, inexpensive to produce comparative to other designs. Classical design is a 4 element design in 3 groups.

Sonnar f1.5 - High performance lens for CONTAX cameras

In 1934, Dr. Ludwig Bertele created the Sonner f1.5, which improved upon the optics of Sonnar f2.0, boosted the world's fastest aperture and once again surprised the photographic elite. The Sonnar lens diminished reflected light from the lens surface and offered delineation with the sharp contrast found in the Tessar lens.

Characteristic: Uses less elements than Planar, so when coating tech was primitive, much less flare and more contrast due to fewer surfaces for light to cross (element to air or element to element) in design. Simpler than Planar, smaller and comparatively less expensive.
