Nikon's high-grade HG L series binoculars bring everything into focus and uncover the beauty of the world around you. Topping off Nikon's acclaimed lineup of binoculars, the six HG L series models are designed for unparallelled performance and comfort. Advanced lens and prism construction delivers sharp, bright images that intensify your viewing experience. Other elements, such as the user-oriented optical and mechanical design, work together to reveal fine details you'd have otherwise missed. And in 42mm objective diameter models, the weight has been significantly reduced. What's more, environment-friendly materials extend the quality of the HG L series even further.
The overall result is something Nikon believes all binocular users should experience: more moments of clarity.
Light transmission rates

Generally speaking, the higher the light transmission rate of a lens, the brighter and clearer your image will be, with less blur and ghosts. Each of Nikon's high-grade binocular models features a high light transmission rate thanks to our multilayer-coated lenses and prisms.
