The Leupold 171386 model - known as the VX-5HD, is renowned for its blackened lens edges. This particular feature minimises undesired glare and diffusion through the lens borders, subsequently providing enhanced resolution, improved contrast, and superior optical performance. The VX-5HD is also recognized for its extreme fast-focus eyepiece which guarantees a generous eyebox, an outstanding field of view and optimal diopter adjustment while out in the field. Moreover, it has a user-friendly design allowing users to adjust through the full range of diopter settings in a single rotation of the eyepiece.
