The ZEISS SFL 10x30 combine powerful 10x magnification with a remarkably compact design weighing just 460 g. Their 120 m to 1,000 m field of view retains excellent versatility for spotting and observing birds from a distance.
The UHD (Ultra High Definition) optical concept delivers an excellent level of detail and natural color reproduction. FieldFlattener technology maintains excellent sharpness all the way to the edges, while 90% light transmission ensures a clear, high-contrast image.
The SmartFocus system allows for fast, precise focusing, while the ZEISS T* and LotuTec® coatings optimize image quality and protect the lenses in the field.
For me, the distinction within the range is very clear: SFL 10x30 = priority on compactness and lightness; SFL 10x40 = more light comfort, but with an additional 180 g.
