ZEISS objektivi

A lens with relatively few glass-air surfaces, it was developed by Dr. Ludwig Bertele at ZEISS in 1930. At the time it was one of the fastest high-speed lenses for 35 mm photography, with apertures as large as 1:1.5 and high contrast thanks to effective stray light reduction. Its high speed and high contrast helped give the lens its name, which is derived from the word “sun,” the symbol of maximum brightness. You continue to find the aforementioned benefits with modern lenses in the normal and telephoto ranges whose optical design is based on this basic type.
