ZEISS SFL® 40 – The New Compact Binocular from ZEISS

ZEISS introduces new binoculars featuring maximum optical performance with a lightweight and compact design for your next hunt.

ZEISS is excited to introduce the ZEISS SFL 40, the newest member of the ZEISS SF line of binoculars. The ZEISS SFL (SmartFocus and Lightweight) provides exceptional optical performance combined with a compact and lightweight design. The new binoculars come in two models, the ZEISS SFL 8×40 and 10×40. “Our new ZEISS SFL 40 allows users to experience special hunting moments with incredible ease by combining the advantages of high-performance binoculars with the compact design of smaller binoculars,” said Tammo Lueken, Head of Category Management Hunting at ZEISS.

Lightweight and Compact Design

“Especially when on long hunts in challenging terrain, all of the gear you carry can become a burden as every ounce adds up,” Lueken explained. “That’s why our primary goal was to develop binoculars that are not only lightweight, compact and tripod adaptable, but also offer incredible image quality for memorable moments in the field.” Thanks to the reduced lens diameter, the use of thinner and more closely spaced lens elements, and the rugged and durable magnesium housing, the ZEISS SFL 40 is an exceptionally lightweight yet reliable companion. 

Color Fidelity and Sharpness of Detail – Thanks to New UHD Concept

The new Ultra-High-Definition (UHD) concept offers exceptional color fidelity and high image resolution thanks to the perfect combination of optimized lens coatings and a sophisticated optical design for a truly natural and immersive viewing experience. The 90% light transmission and T* multi-coating deliver an impressive image; even in twilight conditions. ZEISS’s proprietary FieldFlattener technology provides edge-to-edge clarity, with a wide field of view of up to 420 feet at 1,000 yards on the 8×40 model. Adding in a close focusing distance of 4.9 feet, the binoculars deliver an incredible combination for viewing up close as well as at a distance. “Combining high image resolution and precise immense detail recognition, the ZEISS SFL allows hunters to observe even the slightest movements, like the flicker of a deer’s ear in dense brush,” Lueken reports. This is complemented by the LotuTec® coating on the lenses, which guarantees a clear view even in rain and mud thanks to its beading effect. 

Simple, Intuitive Operation with Perfect Ergonomics

“When observing wildlife while hunting, sometimes a few seconds can be crucial in order not to miss the perfect moment for a responsible shot. That’s why it’s so important that users can operate the binoculars intuitively and easily,” Lueken added. Thanks to the proven SmartFocus concept and the ideally positioned focusing wheel, users can focus quickly and precisely, even when wearing gloves. Using only 1.4 rotations to go from close focus to infinity, the SFL is the perfect combination between speed and precision. In combination with the improved eyecups and the very large exit pupil in relation to the binoculars’ compact size, the ZEISS SFL delivers a comfortable viewing experience, even in twilight.
