Built for your outdoor adventures

Want a rugged, high-performance pair of binoculars for all of your outdoor activities? The Fujinon POLARIS™ FMTR-SX combines 7X magnification with a durable, all-weather body. It makes a great pair of "long-distance eyes" for nature watching, sporting events, and even checking out the moon.

The POLARIS series difference

POLARIS series binoculars strike a nice balance between optical performance, durability, and size. They use a unique EBC (Electron Beam Coating) coating that allows 95% of light to pass through. These binoculars feature a wide, "sticky" grip that makes them very easy to hold — even in wet conditions.

POLARIS binocs are also waterproof and fog-proof, so they'll hold up under less-than-ideal weather conditions.

My firsthand experience

I brought a pair of POLARIS™ binoculars home to test for a few weeks. I found them to provide a clear, bright view. The individually adjustable eye cups allow you to precisely dial in the focus for your eyes. The icing on the cake: the objective lens caps are tethered to its body, so you don't have to worry about losing them.

    Hands-on research

    Product Research


    Overview: The Fujifilm Polaris FMT-series binoculars are built for marine use, professional fishing, and other severe environments. They can also be used for for astronomical viewing, hunting, camping, and other rugged activities. FMT-series binoculars come with a comfortable neck strap, an eyepiece cover, integrated objective lens covers, and a cleaning cloth.

    Construction: The FMT-series binoculars feature a rugged cast light-alloy body with high-grade optics and water resistance. The rubber armored body and textured outer tubes give you a firm grip, especially in wet conditions. The binoculars are dry-nitrogen purged for 100% waterproof construction that meets and exceeds military specifications. The binoculars can be used in temperature extremes from -20°C to +50°C (-4°F to +122°F).

    Fujinon EBC Coating: Polaris FMT-series binoculars feature the unique EBC coating (Electron Beam Coating) from Fujinon applied to every optical surface. This coating allows 95% of light to pass through the binoculars, making them ideal for use low light conditions. In addition, the binoculars have anti-reflection fully multi-coated lenses.

    Field Flattener Eyepiece: The eyepiece features high-grade "field flattener" lenses which give you sharp images from edge-to-edge without any distortion or discernable astigmatism.

    Individual Eyepiece Focus: The FMT-series binoculars lack a center focus control, but have individual focus controls for each eyepiece. Users with normal eyesight will find distant objects are clearly in focus when the diopter scales of each eyepiece are set to 0. Near or farsighted users should adjust each eyepiece until each eye sees a sharp, perfectly focused distant image. Each eyepiece can be adjusted by + or - 5.

    Rubber Eyecups: The non-adjustable rubber eyecups offer extra long eye relief (23mm), allowing you to get a full field-of-view through the binoculars. If needed, the eyecups can be folded over for viewing with eyeglasses. The binoculars have a wide interpupillary distance adjustment so that you are viewing a single image when looking through the eyepieces. The hinge has scale markings so you can observe your own personal setting if the binoculars are used by others.

    Tripod Adapter Socket: The FMT-series binoculars offer a 1/4"-20 threaded socket at the end of the central axis for attaching an optional tripod adapter (sold separately). The socket is covered by a screw-in cap.

    Limited Lifetime Warranty: The Fujifilm Polaris FMT-series binoculars are protected by a Limited Lifetime Warranty. The warranty applies to the original end user, and does not cover rubber or accessories.
