When I bought it only, the sound was recorded strangely. The noises are crackling, as if someone is constantly blowing into the microphones. Then it just went away. But the sound vseraveo is so-so if the interview. Autofocus is generally a problem. Constantly loses focus. It is better to shoot close-up objects only with a connected smartphone, otherwise you will not notice how the focus has disappeared and you will shoot soap.
