Sooner or later, your shooting time and bad weather will collide. This is why ZEISS developed LotuTec®. A protective exterior lens coating for ZEISS optics that enables a clearer and unhindered view in all weather conditions. It helps to greatly repel rain, snow, dust, and fingerprints, and makes lens cleaning easier.
ZEISS T* coating is a guarantee of the brilliant, high-contrast images which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.
