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:

- Lens protection 2 pcs.

- Carry bag with adjustable strap
- Multilingual instruction

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.


Appearance
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.



Conclusion

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.
