For reference only, recently, someone used 70D to shoot for two hours, and the camera motherboard burned, and the manufacturer did not guarantee it. It's ok to shoot video with a SLR, but it's mainly to take pictures. More than 7 D2 6000, high-definition cameras are generally in their early 3000 s, which is enough for civilian use. It is easy to shorten the service life and consume a lot of power when shooting video with SLR. For reference only.
