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.)
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.
