Features Lightweight Because every ounce counts. The lightweight yet rugged magnesium housing also enhances durability and longevity – for generations to come. The smaller lens diameter allowed us to use thinner lens elements that could be installed closer together. At the same time, the SFL binoculars offer a perfect image quality despite the incredible reduction in weight and volume. Reliably identify targets The Ultra-High-Definition (UHD) concept features a special coating and an improved optical design that ensures the binoculars deliver the highest level of detail and reproduce colors with natural fidelity. This means you can recognize even the smallest features and identify the game reliably. SmartFocus Concept for an intuitive and precise handling The SmartFocus concept makes it possible to focus quickly and precisely – without having to spread your fingers. The focusing wheel, perfectly positioned in the DoubleLink Bridge, offers the highest level of operating ergonomics, requiring only 1.4 turns from close focus to infinity and capable of being rotated precisely even with gloves on. 90% Light Transmission Featuring 90% light transmission and ZEISS T* multicoating, you can clearly and precisely recognize details in the twilight, ensuring that you capture every moment, even in darker environments. Comfortable viewing experience The perfect ergonomics of the ZEISS SFL models enable quick and easy positioning of the eye and also provide comfortable and immersive viewing due to the large exit pupil. 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. This is why ZEISS developed LotuTec®. A coating for the lenses of binoculars and spotting scopes that enables a clear and unhindered view in all weather conditions.
