In addition, the improved eyecups provide an even better ergonomic feel and a smooth transition between the touch points, which are precisely defined and can be reached perfectly.; Zeiss T Coating - 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.; A Clear View, Whatever the Weather - There are always exciting things to be seen in the world of nature – even in wet weather.
