8A Clear View, Even in the Rain
Lightweight, compact, and ergonomic, these 8x40 SFL Binoculars combine ease of use with the premium optical quality ZEISS is known for. The SFL (SmartFocus Lightweight) line uses slightly smaller objective lenses for a significant weight reduction from previous models, making a day of nature observation or sightseeing much more comfortable. The expansive 420' field of view aids in following or searching for visual targets. Turn the focus wheel just 1.4 turns for the 5' close-focus distance, assuring a good look at that nearby bird or butterfly. Schott HT glass with the famous T* ("T star") coating delivers 90% light transmission for a beautiful image, even in the low light of dusk or dawn. The 8x40 SFL is nitrogen-filled to prevent internal fogging and is waterproof to a depth of nearly 14'.
The lightweight yet rugged magnesium housing also enhances durability and longevity for generations to come. The smaller lens diameter allowed ZEISS 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 relative to other models.
True Colors for Nature/Wildlife Observation
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 colors with natural fidelity. This makes it possible to precisely identify the smallest features in the plumage and reliably distinguish between species.
SmartFocus Concept for Intuitive, Precise Handling
The 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, you can clearly and precisely recognize details in the twilight, ensuring that you capture every moment, even in darker environments.
The ergonomic 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.
ZEISS T* coating is a guarantee of the brilliant, high-contrast images that you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.
A Clear View, Even in the Rain
There are always exciting things to be seen in the world of nature, even in wet weather. This is why ZEISS developed LotuTec, a coating for the lenses of binoculars and spotting scopes that enables a clear and unhindered view in all weather conditions.
