Zeiss SFL 10x50

ZEISS SFL 10x50 – powerful optics in a compact design
The ZEISS SFL 10x50 is a high-quality binocular for observations where good detail recognition and a bright, high-contrast image are required. The combination of 10x magnification and a 50 mm objective diameter offers a balanced mix of range, brightness, and comfortable viewing.
Whether for nature and wildlife observation, travel, landscape viewing, or other situations where a precise look into the distance matters: the SFL 10x50 brings distant details closer without compromising on high-quality optical equipment.
10x magnification and 50 mm objective
With 10x magnification, even distant subjects can be viewed in detail. The 50 mm objective diameter simultaneously allows for high light intake. ZEISS specifies a light transmission of 90% for the SFL. The exit pupil of the 10x50 is 5.0 mm, supporting a bright and pleasant image. Zeiss
The field of view is 122 meters at 1,000 meters distance. This ensures that despite the 10x magnification, a sufficiently large image section remains, which can be especially practical when observing animals or moving subjects. Zeiss
Detailed images with ZEISS optics
The SFL 10x50 is equipped with high-quality ZEISS T* multi-coatings. These support high light transmission as well as contrast-rich and color-true images, especially under challenging lighting conditions.
The LotuTec® coating on the lenses repels water and dirt, supporting clear vision even in changing weather. The optical equipment is complemented by the Ultra-HD concept and FieldFlattener technology, designed for high detail reproduction and good sharpness up to the edges of the field of view. sportsoptics-shop.zeiss.com
Thoughtful and comfortable handling
In developing the SFL, not only optical performance but also the most comfortable handling possible was considered. The SmartFocus concept positions the focus wheel so it is quickly and precisely reachable. This allows easy adjustment of sharpness for different observation distances. sportsoptics-shop.zeiss.com
The close focus limit of 1.8 meters enables viewing of closer subjects in addition to classic long-distance observation. The diopter adjustment can be set from -4 to +4 dpt, while the eye relief is 18 mm. Zeiss
Compact despite 50 mm objectives
Despite the comparatively large 50 mm objectives, the SFL 10x50 is designed to be compact and lightweight. The magnesium housing and the special arrangement and construction of the lens elements allow a length of only 160 mm with a weight of 872 g. This keeps the binoculars comparatively handy for a 50 mm model.
The housing is also nitrogen-filled and waterproof up to 400 mbar. According to ZEISS, the SFL is designed for a temperature range from -20 °C to +55 °C. This makes it suitable for use under changing external conditions.
For versatile observations
The ZEISS SFL 10x50 is especially suitable for users who want to combine 10x magnification with the light performance of a 50 mm objective. This combination is ideal, for example, for bird and nature observation, landscape viewing, or observing distant subjects.
Here, not only maximum magnification is important but especially a good balance of image quality, brightness, field of view, and handling.
