ZEISS SFL 8X30 BINO BLK 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 the SFL 30 we now offer compact high-performance binoculars in the practical design of pocket binoculars that, thanks to their light weight, do not add to the load, even on longer hunts. With a field of view of up to 142 meters at a distance of 1,000 meters and a closest focusing distance of 1.5 meters, the SFL 8x30 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 23% and their length by up to 21% compared to the ZEISS Victory SF models. As a result, the SFL binoculars are up to 30% lighter than comparable products from competitors.
