Which manufacturer is more successful, Zeiss or Leica?

The positioning of the two is different, and we can't say which is better or worse;

Zeiss, Zeiss is the world's leading optical giant. At present, many lens structures we use are invented by Zeiss, such as the famous Kirk, Tiansai and Plana. At present, many lens designs are their variants or still use their designs.

At present, Zeiss produces a wide range of photographic lenses with a very long product line, including film, TV photographic lenses, medical care, military, surveying and mapping, microscopy, astronomy and other fields. The camera lens is just a branch of it.

Lycra used to be a famous film camera manufacturer, and its lens and fuselage processing technology is unparalleled in the world. Its fuselage design level is not very high, and many later models benefited from the design of Minolta in Japan, but the processing technology and imaging quality of its products are really impeccable. Its antique products are also expensive now.

Its disadvantages are less product lines, few types, less automation than Japanese cameras, and extremely high price.
