The Opticron 10x50 Oregon 4 PC Oasis Binoculars address the particular demands of hunters, birders, and outdoor enthusiasts by delivering bright high-contrast images with accurate true-to-life color and crisp clarity, even when observing from long distances in low and challenging light conditions. The prisms have phase-correcting and highly reflective coatings that boost light transmission and are complemented by anti-reflection fully multicoated optics which provide bright, clear, high-contrast views with accurate color rendition.
