How about gemantech camera in Germany?

Amazon, Best Buy and Yi Bei don't have this brand, so it should not be a first-class brand. Although it is a miscellaneous brand, I observe that the workmanship is still very good, and there should be no big problem.

You should pay attention to the compression ratio and the fineness of the picture. For example, a 32G card can't shoot normally for 2 hours with full power, and the picture can be similar to other cameras when playing. If these can be done, it shows that the cost performance is still quite high.

Whether it is high-grade or not can mainly be seen in the above two points.
