Optimal Optics for Any Occasion

These Fujinon 7x50 FMTR-SX Polaris Binoculars are the perfect choice for a range of glassing applications. They're waterproof and slip-resistant, with long eye relief, making them ideal for use on or around water. Astronomers will love the large objectives and wide exit pupil, allowing them to observe the moon, hunt for comets, and view planets in total darkness. Birders will appreciate the Porro prism optical path, field flattener lenses, and anti-reflection coatings, which provide crisp, clear views with accurate colour representation for positive identification.

Optical Performance

• Optimized for marine use, bird watching, and wide-view astronomy
• Moderate 7x magnification helps to produce a wide exit pupil and long eye relief for enhanced low-light use and easier viewing on rough or rolling seas
• Large 50mm objective lenses boost light-gathering ability for brighter views in challenging conditions such as at dawn and dusk or in heavy fog
• Traditional Porro prism light path presents a rich depth of field to discern the relative position of objects within the field of view
• Integrated field-flattener lenses eliminate distortion at the edges of the field view for a more immersive experience
• Anti-reflection EBC fully multicoated optics boots light transmission to 95% for brighter high-contrast images with accurate Colour rendition
• Generous 395' field of view at 1000 yards

Use and Handling

• Individual focusing eyepieces ensure the sharpest views possible for every user
• Fold-down rubber eyecups contour to the eye socket and block peripheral light from affecting the view
• 56-74mm interpupillary adjustment range
• Exceptional 23mm eye relief presents a generous eye box that allows the optic to be held away from the face, prevents accidental impacts on rough seas, and makes viewing more comfortable with reduced eyestrain
• Wide 7.1mm exit pupil allows you to enjoy the entire view without vignetting, even on rough seas

Construction Details
