Our lightweight 20x80mm is probably the best buy in the Oberwerk line, especially so since it comes with a $45 rugged hard case. Giant 80mm objectives have a serious amount of light grasp, yet they weigh just 4 lbs! Fabulous for astronomy when used with a tripod, and light enough to be hand-held for terrestrial usage, such as wildlife observation and surveillance. Low-reflection broadband multi-coating is used on every air-to-glass surface, including prisms. Light loss due to reflection and scattering is minimized, providing the highest level of light transmission possible. New “slow-focus” provides precise focus control that won’t drift. All Oberwerk binoculars have rugged rubber-armored metal bodies, all-glass lenses, BAK4 prisms, right ocular diopter adjustment, fold-down eyecups, brass 1/4-20 tripod adapter socket, caps, and strap. Our new rugged hard case with custom-cut foam is also included.
