Best Fujinon Binoculars: Reviews of Fujinon Spotting Scopes & Binocs

Our experts rate the best Fujinon binoculars with reviews of Fujinon waterproof & marine binoculars, spotting scopes & Fujinon’s image stabilized binoculars.

Fujinon binoculars are created by a division of Fujifilm, best known for the cameras, film, and other photographic equipment it produces. Fujinon was established in the early 1940’s to explore the world of optics in all its many forms. One of those forms just happened to be binoculars.

Through Fujinon, a great many discoveries have been made in areas as diverse as movie camera lenses and medical imaging. But one of the best things to come of the Fujinon offshoot has been the line of binoculars they manufacture.

Great variety, high quality, and affordable prices make Fujinon binoculars some of the most attractive in the industry.

Fujinon Binoculars: The Lineup

For an overview of the entire Fujinon catalogue of binoculars, here’s a look at the different series available and what makes them special and unique.

Mariner XL

These are high quality Fujinon marine binoculars that have large objective lens diameters, but are able to maintain a reasonable weight. These can easily be carried for long stretches at a time on the river, lake, or ocean.

Nautilus A

These Fujinon waterproof binoculars are also made for marine activity, with nitrogen-filled barrels keeping them high and dry. But even though they were made for water-bound sightseeing opportunities, these are light enough to take with you anywhere.


Perhaps the best of Fujinon’s marine binocs, the Polaris line is designed for use in severe weather conditions. Rugged, air tight, and fully waterproof, the Polaris FMT/MT series is as tough as they come.


The Poseidon line is made up of full-size marine binoculars that are a little too big to take anywhere else but on the boat. These are fully multi-coated and nitrogen-purged for exceptional clarity and a waterproof construction.


For those who need some extra help keeping the image steady, these Fujinon stabilization binoculars have an internal gyro system that keeps your views level. And like most other Fujinon binocs, they’re also waterproof.


This lineup of compact binoculars was made for sheer portability. None of the nine models in this series will drag you down, no matter where you go. They are also all made with the eco-friendly Echo-Glass system to help keep our planet green.


This is the advanced series of image stabilization binocs from Fujinon. They are one hundred percent waterproof and feature a battery-powered microprocessor for its high-tech gyro system.

Beyond these lines of Fujinon binoculars, you can also find an assortment of Fujinon spotting scopes, monoculars, and binocular telescopes available in a variety of styles and sizes.

Fujinon Binocular Reviews: Close-Up on Polaris

If you need a pair of binoculars to take with you as you cruise the waves, without having to worry that they’ll get damaged by the water, then look no further than Fujinon’s Polaris line.

These fully waterproof devices come in a number of different models, including:

  • FMT/MT 7×50 Binoculars
  • FMT 10×50 Binoculars
  • FMT/MT 10×70 Binoculars
  • FMT 16×70 Binoculars

There are various models with each magnification (the number to the left of the X, which denotes how many times an image is enlarged) and objective lens diameter (the number to the right of the X, which refers to the size, in millimeters, of the lens—the bigger the lens, the more light transmission, and also the heavier the equipment) listed above, tailored specifically to your exact needs.

But one thing is quite clear: these were made to see long-distance objects. With such large objective lens diameters, these can not only be used on the water, but also for great nighttime stargazing. The light transmission afforded by a 70mm lens is extraordinary, and the stars will never look brighter than they do through them.

These are rugged devices. They are made to withstand a great deal of torture from both Mother Nature’s wrath and your own clumsiness.

Are there any drawbacks? Only a few. Because the objective lenses are so big, these aren’t the most portable devices. They can wear your arms and neck out pretty quickly if you don’t have a good place to rest them. Also, the individual focus system does take some time getting used to.

All in all, though, these are some mighty fine marine binoculars—you’d be hard-pressed to find better ones anywhere.

Fujinon Binoculars: The Details

Let’s pull away from the Polaris series to give a wide angle view of the technical aspects that run up and down the Fujinon binoculars line. Here, we’ll see how wide the ranges of magnification, Field of View, and objective lens diameter are within the Fujinon catalogue.


With less than two dozen models to choose from, it’s surprising to find that the range of magnification is quite large within this catalogue. You can find a pair of super compact binocs with a magnification of 6x—Nautilus 6×30 AR-SX—or you can find a jumbo image stabilizing model with a magnification of 16x—Stabiscope 16×40 Day. In between, there are models available that are 7x, 8x, 10x, 12x, and 14x. Also, within the binocular telescope line, the range goes from 15x to 40x.

Field of View

The area of your view when looking through a pair of binoculars is called the Field of View—or FOV, for short. The specification is noted 1,000 yards away from a subject and is measured in feet. Fields of View are also known to be measured in degrees, as with Fujinon binoculars. Most models will rest between the 5 and 6 degree field, but there is one as low as 4 degrees—Polaris 16×70 FMT-SX—and as high as 7.5 degrees—KF 8x42H.

Objective Lens

There are two things of note with the range of objective lens diameters in Fujinon binoculars. The first is that it’s quite a large range with plenty of options. The second is that there are some really great ultra compact models. The low end of the range is 24mm, as found with the KF 8×24 H models. The high end is 70mm, like in the Polaris 16×70 FMT-SX. There are also jumbo binocular telescope products with objective lens diameters of 150mm for the best in stargazing light transmission.

Fujinon Binoculars: Consumer Information

There are a few more things we need to discuss before you can make up your mind about whether or not to buy a pair of Fujinon binocs. Switching over to the business side of things, let’s see what prices and warranties look like with these optical devices.

Price Range

Fujinon binoculars are mid-range products in terms of costs. They are certainly not the cheapest sports optics in the business, but nor are they the most expensive. The low end of the price range comes in at $160 for the Mariner 7×50 WP, while the high end tops out at $1,250 for the Techno-Stabi 14×40 with water- and shock-proof casing. In the telescope catalogue, though, you’ll find prices upwards of $10,000 for the stargazing equipment.

Warranty Info

Almost all Fujinon binoculars come with a limited lifetime warranty that protects them from damage on the factory floor and in transit. But there are a few exceptions. The Starscope models have the limited lifetime warranty on the casing and a 30-day warranty on the tubes. With the Mariner series, the limited lifetime warranty is only for 5 years. And for the Techno-Stabi, Techno, Jr., and Stabiscope lines, the limited lifetime warranty covers just 1 year. It may not be the most spectacular warranty system in the industry, but at least manufacturing damages are covered.
