Carl Zeiss Biogon T* 28mm f2.8
The Biogon lens configuration was invented by Dr. Ludwig Bertele and still remains a benchmark design in optical history. It is an immortal design favoured by photographers for many years. An advantage of this lens is that since there is no mirror in the camera very little distance is required between the lens and film.
The lens designers, therefore, could develop the Biogon T* 28mm f2.8 lens with almost perfect correction of distortion. The Biogon T* 28mm f2.8 lens is almost completely symmetrical in design and has lower distortion than Distagon wide-angle lenses on SLRs.
The Biogon T* 28mm f2.8 is a highly regarded lens greatly desired by professional photographers for regular use providing high performance in any shooting situation.
