Features
Because Every Gram Counts
The lightweight yet rugged magnesium housing enhances durability and longevity. The reduced lens diameter allows the use of thinner lens elements installed closer together, helping make the Victory SFL binoculars up to 30% lighter than comparable binoculars while maintaining image quality.

SmartFocus Concept for an Intuitive and Precise Handling
The SmartFocus concept enables quick and precise focusing without having to spread your fingers. The focusing wheel is positioned in the DoubleLink Bridge and requires only 1.4 turns from close focus to infinity. It can also be rotated precisely when wearing gloves.

Bright Images Even in Low Light
With 90% light transmission, a large 50 mm entrance pupil and ZEISS T* multi-layer coating, the Victory SFL 10x40 allows details to be seen clearly and precisely in low-light situations and at dusk.

ZEISS T* Coating
ZEISS T* coating supports brilliant, high-contrast images, particularly in adverse light conditions and twilight. The technology is continuously adjusted to suit new glass materials and requirements.
