Their magnesium-alloy, rubber-armored body is both durable and lightweight. The LX L binoculars are also waterproof, fog-proof, and shockproof, so they can be used in a range of outdoor environments. Like less expensive models, the LX L 8x20 feature multiple anti-reflective lens coatings, optimizing light transmission, but they add silver-coated roof prisms for phase correction, which improves clarity and sharpness. The LX L 10x25 are a similar option, though slightly less compact.
