Chi­nese opti­cal instru­ments are afford­able, but what about their qual­i­ty now? Today we will con­sid­er binoc­u­lars from the famous Chi­nese optics man­u­fac­tur­er Svbony. The SV47 mod­el is man­u­fac­tured with dif­fer­ent opti­cal para­me­ters, the arti­cle will have the F9340B 8x42 vari­ant (i.e. 8x mag­ni­fi­ca­tion and 42mm lens diam­e­ter).

Pack­ag­ing and equip­ment

For this lot there is a fast deliv­ery from a ware­house in the Russ­ian Fed­er­a­tion. The par­cel arrives at the pick­up point of the CDEK com­pa­ny. Packed secure­ly, as it should be for an opti­cal instru­ment. The card­board box with the binoc­u­lars is cov­ered with a film, and the binoc­u­lars are inside in a case with soft walls. There is pro­tec­tion against mois­ture — sil­i­ca gel. Case dimen­sions: 18x13x7 cm.

The opti­cal device is made in Chi­na. War­ran­ty 1 year.

The includ­ed nylon sheath can be worn on the adjustable shoul­der strap or on the waist belt. Hard­ware is actu­al­ly plas­tic. Inside the cov­er there is an addi­tion­al com­part­ment with a zip­per (for exam­ple, you can put a cloth nap­kin).

In addi­tion to binoc­u­lars and a case, the pack­age includes:

  • Eye­piece pro­tec­tion (sin­gle)

  • Lens guards (2 pcs.)

  • Neck strap

  • Mul­ti­lin­gual instruc­tion (with­out Russ­ian lan­guage)

  • Cloth nap­kin for optics

Pro­tec­tors for optics are remov­able, made of flex­i­ble rub­ber. Los­ing is easy. There was no for­eign chem­i­cal smell dur­ing unpack­ing.


The shape of the body of the SV47 is deter­mined by the opti­cal scheme used, name­ly the roof (the lens and the eye­piece are locat­ed on the same axis). The binoc­u­lars are com­pact in width, the dis­tance between the pupils is eas­i­ly adjustable (the mech­a­nism is lubri­cat­ed). You get used to the mass in your hand, you can’t call binoc­u­lars very heavy.

The body is cov­ered with a dense rub­ber-like plas­tic, which increas­es the grip in the hands. On the side, in addi­tion to the eye­lets for the belt, there is an addi­tion­al tex­ture of dots, it is con­ve­nient to hold the binoc­u­lars even with gloves.

Fill­ing the her­met­ic body of the binoc­u­lars with pure nitro­gen is claimed, but this is dif­fi­cult to ver­i­fy. But I note that fog­ging of the optics when the tem­per­a­ture changes (I brought it home from a cold car in the morn­ing) was not noticed. Also, there is a pro­tec­tion of the body from water, which allows you to use the SV47 with­out fear in nature.

Optics are coat­ed with Mul­ti Coat­ed (gives green col­or), which reduces unnec­es­sary reflec­tions and increas­es light trans­mis­sion. Glass is well processed, there are no vis­i­ble defects.

Let’s go through the adjust­ments of the binoc­u­lars.

I have already said about the inter­pupil­lary dis­tance, it is in the range of 55–75 mm, enough for both chil­dren and adults. There is a rotary adjust­ment of the dis­tance (removal) to the pupil, for those who wear glass­es it will be use­ful. Adjust­ment comes with clicks, you can sim­ply set the same dis­tance.

Under the right eye­piece there is a cor­ru­gat­ed met­al diopter adjust­ment wheel.

Focus is adjust­ed by the cen­tral drum, and of course, syn­chro­nous­ly for both eyes. More­over, the drum rotates as it should, a lit­tle tight, but with­out jam­ming and rustling. The min­i­mum sharp focus­ing dis­tance for the SV47 8x42 is 6 meters.

It is also pos­si­ble to mount the obser­va­tion device on a tri­pod, but you need to buy a spe­cial (L‑shaped) adapter. The thread is hid­den under the cov­er in the cen­ter.


The real mul­ti­plic­i­ty of the device is 8, which is con­ve­nient for use in tourism, hunt­ing or observ­ing ani­mals and birds. We get a wide field of view and a min­i­mum of “shake” in the pic­ture when viewed from the hands. But this is not a tele­scope for astro­nom­i­cal obser­va­tions and not marine binoc­u­lars, com­fort­able work­ing dis­tances here are with­in 1 km or less.

For exam­ple, a car num­ber is clear­ly vis­i­ble for ~200+ m:

The pho­to through the eye­piece is bad for me, there are always black fields or loss of sharp­ness. With an eye (and in binoc­u­lars — with two eyes), the pic­ture is much bet­ter, volu­mi­nous and with a min­i­mum of dis­tor­tion.

Let’s look at the pho­to through the eye­piece of the SV47 8x42.

Near zone (100–350 m) and fur­ther (2–3 km).

At the same time, you can com­pare (pho­tographed the same places) with a mod­el with para­me­ters 10X42 (F9340D). Review here. It is heav­ier, and a lit­tle bet­ter approach­es.


Svbony SV47 8x42 is a prac­ti­cal and afford­able binoc­u­lar with good work­man­ship, mag­ni­fi­ca­tion of 8x allows you to con­fi­dent­ly observe from your hands with­out stop­ping. The image through the eye­piece is bright and sharp, dis­tor­tion and chro­ma­tism are at a min­i­mum. The kit is com­plete, every­thing you need to use.
