DESC: With the new Leupold Golden Ring 8x42mm and 10x42mm binoculars we have seriously raised the bar for optical performance. The key is Leupold's exclusive Index Matched Lens System. Each lens coating is matched specifically to the type of glass and the lens placement in the binocular. The result is a standard of brightness, clarity, and color fidelity like you've never seen before. For sensing those subtle variations of color and shade, or pulling out crucial details for a positive ID, these are the binoculars you'll want in hand.
