Zeiss SFL 8x40 Binoculars
SFL – SmartFocus and Lightweight
The great outdoors await with awe-inspiring experiences that you simply don’t want to miss. But longer excursions are often associated with a need to lug around heavy equipment and the resulting neck pain. All the better if the choice of the right binoculars does not add to the burden. This is because, with the new ZEISS SFL binoculars, you can enjoy all those magical outdoor moments with a new level of ease. This model combines all the advantages of high-performance binoculars with the compactness of pocket binoculars, guaranteeing a carefree, comfortable, and outstanding viewing experience.
Because Every Gram Counts
Optimised for a lightweight and compact size in every respect, the SFL series perfectly complements the other binoculars in the ZEISS SF family. 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 perfect image quality despite the incredible reduction in weight and volume.
Experience Nature in All Its Splendor
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 colours with natural fidelity. This makes it possible to precisely identify the smallest features in the plumage and reliably distinguish between species. The high degree of light transmission and the T* multicoating deliver an accurate image, even in twilight conditions. Even in extreme situations such as rain or high humidity, you’ll always enjoy a clear view thanks to the lenses’ LotuTec coating, which water droplets and dust particles simply pearl off of. The ergonomics of the new ZEISS SFL models have been optimised to make positioning the eye quick and easy, providing a comfortable and immersive viewing experience.
Everything Under Control
Zeiss' proven SmartFocus concept makes handling the binoculars easy and comfortable. It includes a perfectly positioned focus wheel in the DoubleLink Bridge for fast and precise focusing – even when wearing gloves. Whether you have everything in view or an eye for the smallest details, the focusing range from close focus to infinity is only 1.4 rotations apart. Improved eyecups also guarantee an ergonomic feel with smooth transitions between the touch points, which are precisely defined and can be reached perfectly. So that you never miss a moment in the great outdoors.
