These elegant Porro-prism binoculars have excellent optical characteristics. The fully coated optics guarantee a decisively higher light transmission through the glass, thus increasing color fidelity and contrast. Diopter compensation is standard with these models. This makes these binoculars suitable for beginner birders or nature observers. The 50-mm objective lenses gather enough brightness for observation even in twilight conditions.
