Premium Optics and Ergonomic DesignLightweight, compact, and ergonomic, these 10x40 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. You'll enjoy the generous field of view for the big picture and the 5' close-focus distance for 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 SFL is nitrogen-filled to prevent internal fogging and is waterproof to a depth of nearly 14'.
