Binoculars ZEISS SFL 10x50:
optical excellence in a compact and lightweight design
The zeiss SFL 10x50 binoculars embody the perfect combination of cutting-edge optical performance and exceptional compactness, designed for enthusiasts of birdwatching, astronomy, and natural landscapes. Available on qualioptic.com, these binoculars from the SFL (SmartFocus Lightweight) range deliver flawless image quality, optimized ergonomics, and impressive lightness, rivaling traditional 42 mm models.
Whether you are a birdwatcher seeking to identify a rare bird or an amateur astronomer observing the stars, this model is an ideal companion for all your outdoor adventures.
An innovative design for unmatched lightness
The design of the zeiss SFL 10x50 binoculars is a technological achievement by ZEISS, a brand globally recognized for its optical expertise since 1846. Thanks to a strategic reduction of the lens diameter by 2 mm compared to traditional models, the optical elements are thinner and closer together, reducing the weight by 20% and the volume by 13% compared to ZEISS Victory SF models.
Weighing only 872 g, these binoculars offer the lightness of a 42 mm model while retaining the brightness of a 50 mm objective.
A robust magnesium construction
The binoculars’ housing is made of a magnesium alloy, a material that is both lightweight and extremely durable. This robust construction ensures exceptional longevity, even for future generations, while protecting the internal optical components.
Shock-resistant and built to withstand harsh conditions, the SFL 10x50 are ideal for outdoor use, whether in the forest, mountains, or humid environments.
Three formats to meet all needs
The SFL 50 series comes in three formats to suit your observation preferences: 8x50, 10x50, and 12x50. The 8x50 model offers a wider field of view (131 m at 1000 m), perfect for landscapes and birdwatching.
The 10x50, with a 122 m field of view, balances detail and stability, making it ideal for hunting or wildlife observation at medium distances. Finally, the 12x50, with higher magnification, is designed for observations requiring maximum detail, such as astronomy.
Exceptional optical quality thanks to the UHD concept
At the heart of the zeiss SFL 10x50 binoculars is the Ultra High Definition (UHD) concept, which ensures faithful color reproduction and impressive sharpness.
This advanced optical system allows you to precisely identify the finest details, such as a bird’s plumage or lunar craters, even in low-light conditions. The multi-coated lenses ensure a 90% light transmission, delivering clear and bright images.

zeiss T* coating for brilliant images
The ZEISS T* coating applied to the lenses of the SFL 10x50 is an advanced technology that maximizes contrast and brightness. This coating reduces glare and enhances clarity, even at dusk or in poor weather conditions. Whether you are observing a deer at dawn or a constellation on a clear night, this treatment ensures an exceptional visual experience.
LotuTec coating for clear vision in all weather
The binoculars are equipped with the LotuTec® coating, an innovation from ZEISS that repels water, dirt, and fingerprints. This treatment ensures a clear view, even in rain or humid conditions. During a rainy hike or coastal observation, the lenses remain clean and ready for use, allowing you to focus on your subject.
A wide field of view to miss nothing
With a field of view of 122 m at 1000 m, the SFL 10x50 binoculars provide a perfect overview for tracking moving subjects, such as birds in flight or wildlife. This wide field is especially valued in birdwatching, where locating a subject in dense environments can be challenging. The apparent field of view of 66° enhances this immersive experience.
Close focus distance for detailed observations
The SFL 10x50 also stand out with their close focus distance of 1.8 m. This feature is an asset for observing nearby subjects, such as insects or flowers, without changing equipment. For example, during a walk in the forest, you can easily switch from viewing a butterfly a few meters away to a raptor perched in the distance.
Optimized ergonomics with the SmartFocus concept
The SmartFocus concept is at the heart of the SFL 10x50’s ergonomics. The focus wheel, perfectly positioned in the DoubleLink Bridge, allows for quick and precise adjustments, even when wearing gloves. In just 1.4 turns, you can go from close focus to infinity, ideal for tracking moving subjects. This intuitive design is a real advantage for long observation sessions.

Balanced handling for long-lasting comfort
Thanks to their optimized center of gravity, the zeiss sfl 10x50 binoculars offer perfectly balanced handling. This design reduces muscle fatigue, even after several hours of use. Whether you are on a stakeout for birdwatching or hiking to admire landscapes, these binoculars remain comfortable to hold and operate.
Ergonomic eyecups for all users
The eyecups of the SFL 10x50 are designed to provide maximum comfort. With a 20 mm eye relief and adjustable positions, they suit both eyeglass wearers and other users. The large 5 mm exit pupil ensures an immersive and effortless viewing experience, even during extended observations.
Perfect for astronomy and birdwatching
The zeiss SFL 10x50 binoculars are particularly well-suited for amateur astronomy and birdwatching. Their 50 mm objective lens gathers a large amount of light, making stars and constellations visible with remarkable clarity. For birdwatching, the 10x magnification allows you to spot fine details, such as feather patterns, at medium distances.
Versatility for natural panoramas
In addition to their performance in astronomy and birdwatching, these binoculars excel at observing natural panoramas. Their wide field of view and image sharpness make them an ideal tool for exploring mountain landscapes, valleys, or coastlines. You can capture all the beauty of a sunrise or a clear horizon with unmatched precision.
Resistance to all conditions thanks to waterproofing
With waterproofing up to 4 meters deep, the SFL 10x50 are ready to take on the most demanding environments. They are also nitrogen-filled to prevent internal fogging, even during sudden temperature changes. Whether you are caught in a downpour or in freezing conditions, these binoculars maintain their performance.
Extreme temperatures: a reliable companion
The binoculars operate flawlessly in a temperature range from -20°C to +55°C, and can be stored between -30°C and +70°C. Whether you are observing the northern lights in the Arctic or wildlife in a tropical forest, the SFL 10x50 are engineered to withstand any climate.
Twilight factor for low-light observations
The twilight factor of 20.5 for the SFL 10x50 makes them an excellent choice for observations at dusk or dawn. This factor, combined with 90% light transmission, allows you to discern details in low-light conditions, such as an owl taking flight at sunset.

An ideal companion for long observation sessions
