The Fujinon 7x50 FMTR-SX Polaris Binoculars is outfitted with a suite of optical and design elements that make them an ideal optic for a variety of glassing applications. For those jobs on and around water they feature waterproof seals, slip-resistant armor, a wide exit pupil, and long eye relief. For astronomers who like to view the moon, hunt for comets, or enjoy wide-field viewing of planets, the large objectives gather buckets of light while the exit pupil is wide enough to still cover fully dilated pupils in total darkness. Birders will appreciate the Porro prism optical path, field flattener lenses, and anti-reflection coatings that ensure crisp and clear views with accurate color representation that will allow positive identification of elusive species.
