Fujinon 7x50 FMT-SX
The Fujinon FMT-SX 7x50 is a big and solid pair of binoculars from the top-of-the-range series of this renowned producer which also includes the following models: 8x30 (most likely not produced any more), 7x50, 10x50, 10x70 and 16x70. All of these instruments are equipped with huge Porro prisms. The binoculars meet US military specifications regarding ruggedness and resistance against pressurized water –according to M24 specification they are shock-proof and also sea waterproof. Their lenses and prisms are digitally designed, made of BaK-4 glass and fully multi-coated using special EBC technique (Electron Beam Coating) which allows as much as 99.9% of light pass through one air-to-glass surface. Such an antireflection layer reduces light flares and is sea waterproof. According to the producer the light transmission for the whole instrument can exceed even a very high level of 95%.
The binoculars of this series are sold in two versions: the FMT-SX and the FMTR-SX. The second one is additionally rubber-padded but both remain completely waterproof and nitrogen filled. The padded FMTR-SX model took part in our big 10x50 class binoculars’ test. In the case of the 7x50 class we decided to test a more classic-looking FMT-SX model.
Buyers get a hard case, a strap, caps and a cleaning cloth in the accessory kit. The binoculars come with a 10-year guarantee of the producer.

Let’s start by comparing the tested binoculars to their most serious rivals – a chart, published below will make it easier. You can notice that among the whole group of sealed Porro devices produced by the most renowned manufacturers the Fujinon provides the best field of view. It is also one of the biggest pairs of binoculars in this class and definitely physically the heaviest – those huge Porro prisms and a solid casing have to weigh a lot.
In the photo below the tested instrument is situated next to the Docter Nobilem 7x50 B/GA. You can see clearly that we deal here with two binoculars of roughly the same dimensions. Large eyepieces of the Fujinon stick out – they are definitely bigger than those of the Docter.
The Fujinon impressed us especially with its transmission. Although the results presented by its competitors like the Steiner Commander or the Docter Nobilem were splendid as well, those of the Fujinon are simply brilliant. In the middle of the visible spectrum the transmission reaches the value of 98% and an excellent level of over 90% is kept in a wide range of wavelengths, from 430 to 680 nm.
The binoculars didn’t manage to avoid some slip-ups. Too light area around exit pupils and the shape of these pupils, as they are slightly truncated despite those huge prisms, can be counted among them. These flaws are not very important, though, and they are easily compensated by very good or downward excellent achievements in other categories. Overall the final score in our test reached a splendid level of over 146 points. Only few other pairs of binoculars managed to accomplish such a feat and all of them are far more expensive than the Fujinon, tested here.
We can write with a clear conscience that the Fujinon FMT-SX 7x50 is one of the best pairs of binoculars available on the market at a not especially steep price when you compare it to the possibilities of that instrument. We do recommend it wholeheartedly!
