Sfl 10x40 binoculars - ZEISS

Thanks to the SmartFocus concept, the focusing ring is perfectly positioned and allows fast and precise focusing, even when wearing gloves. Optimized ergonomics and a large exit pupil allow for a relaxed and undisturbed view.
With a field of view of up to 115 meters at a distance of 1,000 and a close focusing distance of 1.5 meters, the SFL 10x40 transmits a perfect overall vision combined with precise recognition of details.
The diameter of the lens has been reduced by 2 mm, allowing the use of thinner and closer lenses and therefore reducing the weight of the binoculars by up to 20% and their volume up to 13% compared to ZEISS Victory SF models. As a result, SFL binoculars are up to 30% lighter than similar competitive products.
The lightweight yet robust magnesium hull therefore improves durability and longevity for generations to come. The smaller lens diameter has allowed us to use thinner lenses that can be mounted closer together. At the same time, SFL binoculars offer perfect image quality despite the incredible reduction in weight and volume.
The Ultra-High-Definition (UHD) concept features a special treatment and an improved optical design that ensures binoculars offer the highest level of detail definition and faithful color reproduction. This means that you can recognize even the smallest details and identify prey reliably.
The SmartFocus concept allows fast and precise focusing, without having to spread your fingers. The focusing ring, perfectly positioned in the DoubleLink bridge, offers the highest level of operational ergonomics, requiring just 1.4 turns from close focus to infinity and capable of rotating precisely even when wearing gloves.
