Some 5 years ago even thought it was impossible that the Chinese video and photography can be some decent competition brands known throughout the world, today our Chinese friends are beginning to fill this gap. Let the technology of these devices are used license, the devices themselves work easier in functionality and is likely to be devices of last generation, but the price negates all these minor flaws.
I want to draw your attention to the action camera from Xiaomi – Yi 4K, which is a worthy analogue of the action Cam from Sony (the line GoPro model Hero4).
And so, once we compare this camera with a trendsetter in the field of action cameras, we will make a comparative rating plate camera Xiaomi Yi 4K GoPro Hero4 and Sony. In addition, a Chinese manufacturer puts in their cell and their matrix, which is also symbolic.

The camera is available only in two basic colors. On the other hand, why is that bad? I would accept if the color was all one, for example, gray.
The design and form of action-camera too, no complaints. At the time, Sony chose a very good Thomas and the size of the body that have passed the test of time. Xiaomi went the beaten track – and rightly so.
Still, what is important for the budget of products of this kind due to the presence of a gyroscope, which permits, even by means of electronic stabilization, but this very stabilization to do.
Camera features Yi 4K, which make its use as comfortable as possible:
- The inclusion of the entry in one press 3 seconds / start shooting when the camera is on for 1 second;
- Image stabilization;
- Increased battery capacity;
- Correction of lens distortion;
- Sensor from Sony;
- Quality, by the standards of action cameras, display;
- A huge number of shooting modes;
- Full 4K.
In General, good and inexpensive camera for everyday purposes.
Only don’t skimp and get to it once all of the necessary accessories. Plus a mandatory order one or two batteries on the stock and the additional device if you take lots of photos.
