The 42 mm Ultravids impress with all benefits of the new HD-models, for example the water and dirt repellent Leica AquaDuraTMcoating and the innovative FL lens glass. A specific benefit of the ergonomic design of the LEICA ULTRAVID HD models: the formed thumb supports on the rear of the 50 mm and 42 mm HD models ensure that the binoculars fit in your hands without slipping. Also the large central focusing device enables relaxed, natural handling.
