Leica is famous for its sharp optics, which have been key to their legendary cameras. They apply that same imaging know-how to these Trinovid 10 x 42 HD Binoculars. As the name suggests, they deliver 10x magnification through impressive 42mm front lenses and the ability to focus on objects as close as 5.3 feet. The housing is also similar to its cameras, with a nitrogen-filled magnesium case given a full rubber wrap for added durability, including water resistance down to 13 feet.
