The ZEISS SFL binoculars (SFL stands for SmartFocus Lightweight) are optimized to be as lightweight and compact as possible. The new binoculars are offered in 10×40 and 8×40 configurations.
The new ZEISS Ultra-High-Definition (UHD) offers true-to-life color reproduction and the highest level of detail and the SmartFocus design places the focus wheel in perfectly position for fast and precise focusing, even with gloves on. The optimized ergonomics and a large exit pupil allow for a relaxed and undisturbed viewing experience.
The 8×40 model offers 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 10×40 version offers a field of view of up to 115 meters at a distance of 1,000 meters and a closest focusing distance of 1.5 meters.
The ZEISS SFL binoculars 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.
The lightweight and rugged magnesium housing enhances durability and longevity. The smaller lens diameter allowed ZEISS to use thinner lens elements that could be installed closer together to offer a high quality image despite the reduction in weight and volume.
The ZEISS Ultra-High-Definition (UHD) design 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 easily.
The ZEISS SmartFocus concept 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, the ZEISS SFL binoculars can clearly and precisely recognize details in the twilight, ensuring that you capture every moment, even in darker environments.
The perfect ergonomics of the ZEISS SFL models enable quick and easy positioning of the eye and also provide comfortable and immersive viewing due to the large exit pupil. In addition, the improved eyecups provide an even better ergonomic feel and a smooth transition between the touch points, which are precisely defined and can be reached perfectly. The ZEISS LotuTec coating of the lenses of its binoculars enables a clear and unhindered view in all weather conditions.
