ZEISS SFL 10x50 Binoculars – Lightweight Power with Stunning Clarity
The ZEISS SFL 10x50 binoculars deliver premium optical performance in an exceptionally lightweight and compact design, rivalling even traditional 42mm models. Combining 10x magnification with a large 50mm objective lens, they offer both detailed observation and outstanding brightness, making them ideal for birdwatching, wildlife viewing, and nature exploration from dawn until dusk.
Ultra-High-Definition Optics
Thanks to the ZEISS Ultra-High-Definition (UHD) Concept, these binoculars provide razor-sharp resolution, vivid colour reproduction, and an impressive level of detail. This advanced optical system makes it easy to distinguish subtle plumage features, fine textures, and even the smallest movements in nature.
SmartFocus Ergonomics
The innovative SmartFocus Concept ensures smooth, precise focusing without unnecessary finger movement. The perfectly positioned focus wheel within the DoubleLink Bridge requires only 1.4 turns from close focus to infinity, giving you fast and accurate control – even when wearing gloves.
Bright and Clear, Even in Low Light
With an impressive 90% light transmission, ZEISS T* multi-layer coating, and large 50mm objective lenses, the SFL 10x50 delivers bright, high-contrast images even in twilight or overcast conditions. Whether scanning open landscapes or following birds in shaded woodland, you’ll enjoy consistently clear views.
Comfortable Viewing Experience
Designed with ergonomics in mind, the SFL 10x50 offers a large exit pupil for relaxed, immersive viewing. Improved eyecups provide a smooth, comfortable fit and easy eye positioning, reducing fatigue during long observations.
ZEISS T* and LotuTec® Coatings
