was bought as a worthy device, which I switched to after 450 Kenon. I chose between Pyatdvak and 7D, there was not enough money and outweighed 7D. I was satisfied with everything, until during the shooting all the buttons stopped working and the device itself stopped working. And this is only after 8.5 thousand frames. now he is in the service, where they shook their heads and said that they would return it no earlier than a month .
