Zeiss SFL 12x50

ZEISS SFL 12x50 – detailed observation with high magnification
The ZEISS SFL 12x50 combines 12x magnification with a 50 mm objective diameter, making it especially interesting for observations where a highly detailed representation of distant subjects is important. Whether for nature and bird watching, traveling, or observing distant landscapes – the binoculars allow a close look at details that quickly get lost to the naked eye.
The 12x magnification brings distant objects significantly closer. At the same time, the 50 mm objective ensures a correspondingly large light intake. The ZEISS SFL 12x50 achieves a light transmission of 90% and has an exit pupil of 4.2 mm. This creates a bright and detailed image, even when lighting conditions are no longer optimal.
High-quality ZEISS optics
For natural color reproduction and high detail fidelity, ZEISS uses the Ultra-HD concept in the SFL. The high-quality ZEISS T* coating supports high light transmission and good contrast. Additionally, the lenses are equipped with the LotuTec® coating, which repels water and dirt, supporting clear vision even in changing weather conditions.
The FieldFlattener technology contributes to good sharpness up to the edges of the field of view. This is especially helpful when observing landscapes, animals, or larger scenes, as not only the image center but also the surrounding area can be perceived in detail.
Comfortable handling
A special feature of the SFL series is the SmartFocus concept. The focus wheel is positioned for quick and precise operation. This allows the focus to be easily adjusted, for example, when an observed animal moves or when switching between different distances.
With a close focus limit of 1.8 meters, the binoculars are suitable not only for distant subjects but also allow observation of nearer objects. The eye relief is 18 mm, and the diopter adjustment ranges from -4 to +4 dpt.
For different applications
The ZEISS SFL 12x50 is especially suitable for users who want to combine high magnification with powerful optics. The 12x magnification is interesting, for example, in bird and nature watching when animals are to be observed from greater distances. The combination of magnification and 50 mm objective can also show its strengths in landscape observation or on the go.
The field of view is 105 meters at 1,000 meters distance. The binoculars are also nitrogen-filled and waterproof up to 400 mbar.
