Fujinon 7x50 FMTR-SX Polaris Binoculars

These Fujinon 7x50 FMTR-SX Polaris Binoculars are designed with a range of optical and structural features, making them perfect for various viewing needs. Ideal for marine and water-based activities, they offer waterproof seals, slip-resistant armour, and extended eye relief. For those interested in astronomy, the large objectives capture ample light, and the wide exit pupil accommodates fully dilated pupils in darkness. Bird watchers will benefit from the Porro prism optical system, field flattener lenses, and anti-reflection coatings, which deliver sharp, clear images with precise colour accuracy for identifying even the most elusive species.

Optical Performance

• Optimised 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
