ULTRAVID are brighter, sharper and more rugged than many other glasses with this lens diameter. Their high level of optical and mechanical performance is the result of specially designed eyepieces. The construction guarantees a sharp view without colour fringing from edge to edge. In addition, the full rubber-ammo  makes the Leica Ultravid BR very resistant and reliable in any situation.

The Leica Ultravid BR models are available with front lens diameters of 20 and 25mm.
