Today’s review is ded­i­cat­ed to a pow­er­ful opti­cal device — binoc­u­lars from SVBONY. Mod­el SV47 is built on a BAK4 prism, has a mag­ni­fi­ca­tion of 10 times and a lens diam­e­ter of 40 mm, and good water pro­tec­tion accord­ing to IPX7 is declared. Let’s check it in action.

Packaging and equipment

Binoc­u­lars are com­plex opti­cal instru­ments and should be care­ful­ly pack­aged. SVBONY is all right with this: inside the trans­port pack­age there is a card­board box, and in it are binoc­u­lars in a case.

The device is made in Chi­na.

SV47 scope of deliv­ery:

  • Binoc­u­lars
  • Eye­piece pro­tec­tion
  • Lens pro­tec­tion 2 pcs.
  • Neck strap
  • Car­ry bag with adjustable strap
  • Mul­ti­lin­gual instruc­tion
  • cloth nap­kin

Pro­tec­tive eye­pieces and lens­es are remov­able, made of flex­i­ble rub­ber.

The com­plete case is solid­ly sewn from dense nylon. It clos­es with Vel­cro, and inside there is even a sec­tion under the zip­per. The cov­er can be hung on a belt, it will be con­ve­nient for some­one. The weight of the set is 0.8 kg.


The binoc­u­lars are made of soft-touch rub­ber­ized mate­r­i­al. This is an addi­tion­al pro­tec­tion against dam­age, and allows you to secure­ly hold the mod­el in your hands.

On the side of the case are eye­lets for attach­ing a belt. The mod­el has a fill­ing with inert nitro­gen, which pre­vents the win­dows from fog­ging up when the weath­er changes. The case is pro­tect­ed from water, can be used with­out risk, for exam­ple, hunt­ing from the water or in the rain.

There is a rotary adjust­ment of the dis­tance to the pupil, for those who wear glass­es. Adjust­ing the dis­tance between the pupils as usu­al frac­ture. Focus is adjust­ed by a drum in the cen­ter of the binoc­u­lars syn­chro­nized for both eyes. On the right side of the diopter cor­rec­tion rotary ring.

Exit pupil 4 mm, lens 40 mm (and glass diam­e­ter 44 mm) — fits 40 mm into the eye­piece if you put a cir­cle on the lens. The mul­ti­plic­i­ty of the device is 10.

An L‑shaped adapter is required for flat or tri­pod mount­ing. It is screwed into the cen­tral focus drum from the front. It must be pur­chased sep­a­rate­ly.

Com­par­i­son with the Beileshi 8X40 I test­ed. The dif­fer­ence in the size of the opti­cal cir­cuits is imme­di­ate­ly vis­i­ble, the reviewed SV47 is built on the roof, and Beileshi on the Por­ro. The roof scheme is more com­pact in terms of the width of the binoc­u­lars.

And the dif­fer­ence in field of view and mag­ni­fi­ca­tion. Mobile->Beileshi 8X40->SV47 10x42

In work

Just a warn­ing: the pho­to in the top­ic as an exam­ple, it is dif­fi­cult to assess the qual­i­ty of the binoc­u­lars from them. Take my word for it, the pic­ture of the SV47 is of high qual­i­ty: sharp, chro­mati­cism and dis­tor­tion in an explic­it form, which cheap binoc­u­lars suf­fer from, are absent here.

It is dif­fi­cult to take a pic­ture with a smart­phone through binoc­u­lars (espe­cial­ly 10x), you need to com­bine the axes of two opti­cal devices, and even focus. And our eye is not a mobile cam­era with a small sen­sor, we look through binoc­u­lars with both eyes, we get a more volu­mi­nous and detailed pic­ture.

The min­i­mum focus­ing dis­tance of the device is 10 meters:

Work exam­ples. Num­bers of cars are read con­fi­dent­ly for 2 quar­ters.

Thanks to fast lens­es, the pic­ture of the SV47 is not bad even at night:

The moon was pho­tographed only with a SLR cam­era, although the relief is vis­i­ble in all details.


SVBONY SV47 10x42 left a pleas­ant impres­sion of use. Binoc­u­lars of this mag­ni­fi­ca­tion are well suit­ed for hunt­ing, shoot­ing, and bird watch­ing. Even the clos­est astron­o­my is pos­si­ble, on a full moon. It’s heavy, yes, but it’s glass, there’s noth­ing to be done.


There is a fast couri­er deliv­ery from a ware­house in the Russ­ian Fed­er­a­tion. From Octo­ber 28 to Novem­ber 12, SVBONY will have the low­est price of the year.

Thank you for your atten­tion. Enjoy the shop­ping!
