With the ZEISS SFL binoculars (SmartFocus Lightweight), special moments can be experienced with ease. Optimized to be as lightweight and compact as possible, the SFL binoculars are 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 1.5 meters, the SFL 8x40 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.
