What are Carl Zeiss optical lenses?

The imaging quality of a digital camera mainly depends on the following three components: lens, CCD and image processing engine. Among them, the lens is the main receiving source of external light, and its quality directly affects the clarity and vividness of the image.

Some digital camera manufacturers use their own lenses, while others use lenses from other specialized manufacturers. The latter situation is still quite common in the industry. Representative examples include Samsung's Schmid lenses, Sony's Carl Zeiss lenses, Panasonic's Leica lenses and Fujifilm's Canon lenses. Today we mainly introduce to you the Carl Zeiss lens used by Nokia on its N90 mobile phone.

Carl Zeiss is a large international company in Germany famous for its production of optical products such as lenses and film cameras.

The glorious history of Carl Zeiss in the history of lens manufacturing began in 1890 with the invention of the Anastigmat, an astigmatic positive photographic lens, invented by the company's engineers. In the same year, the Protar lens was released; in 1896, the Planar lens was released, establishing Carl Zeiss' authoritative position in chromatic aberration correction technology. In 1902, the Zeiss factory designed the 1:6.3 Tessar lens. This lens was bright and sharp, and the image quality was quite good.

As a long-established optical company with a history of more than 150 years, Carl Zeiss is also well-known in the medical manufacturing industry. The microscopes, magnifying glasses, medical endoscopes, camera lenses, glasses and other products it produces are very famous in the world. Among them, the lenses of the Zeiss factory have always been famous for their vivid images, clear details, bright surfaces, anti-color cast and anti- Known for its superior reflective properties. Below, we will briefly introduce a few of the most representative models among the more than 100 camera lenses produced by Carl Zeiss.

*Planar (Planar lens)

Double Gaussian lens, excellent correction of various lens aberrations. Since then, the design of standard lenses of various brands produced around the world has all benefited from Planner.

*Sonnar (Sonnar lens)

Has deep detail fidelity and color balance skills. Unlike the smooth and soft image of the Plana lens, the imaging performance of the Sona is more detailed and sharp. Commonly used for photo and movie shooting.

*Distagon (Distagon lens)

The field of view of the lens is extremely wide, and the wide-angle and telephoto performance are very good. It is also commonly used for photo and film shooting.

*Tessar (Tessar lens)

A lens composed of 3 groups of 4 lenses. The final image is not only bright and translucent in the center, but also has clear details in the corner areas, making it suitable for photo shooting. .

*Biogon (Biogon lens)

This lens invented by Dr. Mehta caused a huge response in the industry at the time. The biggest feature of the lens is that its wide-angle end is almost No lens distortion will occur.

*Hologon (Hologon lens)

Although it does not support large apertures, the distortion of the lens at the wide-angle end is almost zero, and the imaging performance is very excellent.

In fact, many digital cameras are equipped with lenses produced by Carl Zeiss. Taking Sony as an example, its high-end models have never used lenses from other brands except Carl Zeiss. Although there is a saying in the industry that Sony did not directly use Carl Zeiss lenses, but only introduced some optical technologies from Zeiss to produce them on its own, but in any case, Sony camera lenses are deeply influenced by Carl Zeiss from appearance design to internal technology. This is certain. It is precisely because of Carl Zeiss technology that Sony's high-end camera lenses are excellent in terms of imaging and expressiveness. Among the recently launched products, Sony's Cybershot F828 and Kyocera's Contax SL300R are equipped with Carl Zeiss T* lenses.
