We’re absolutely “wowed” by these new Zeiss SFL 8×40 binoculars.  They are in a truly unique niche. They’re full size, high end glass and features, yet they are $1,000 less than the top of the line.

The ZEISS SFL binoculars (SmartFocus Lightweight) have been optimized to be as lightweight and compact as possible, making them a perfect addition to the SF family. The new Ultra-High-Definition (UHD) Concept ensures true-to-life color reproduction and the highest level of detail. Thanks to its SmartFocus Concept, the focus wheel is perfectly positioned and enables fast and precise focusing – even with gloves on. The optimized ergonomics and a large exit pupil allow for a relaxed and undisturbed viewing experience.

With a field of view of up to 140 meters at a distance of 1,000 meters and a closest focusing distance of 4.9 ft, the SFL 8×40 deliver a perfect overview combined with precise detail recognition.

The lens diameter has been reduced by 2 mm, making it possible to use thinner lens elements at closer spacing and thus reduce the binoculars’ weight by up to 20% and their volume by up to 13% compared to the ZEISS Victory SF models. As a result, the SFL binoculars are up to 30% lighter than comparable products from competitors.

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 makes it possible to precisely identify the smallest features in bird plumage and reliably distinguish between species.

SmartFocus 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.

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.

Fully Multi-coated Lenses. ZEISS T* coating is a guarantee of the brilliant, high-contrast images­­ that 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.
