So the problem is with the sd card, I thought it was with the sensor, because also when I put the camera in liveview mode, appears a lot of points and lines on the screen and then freezes And if I took the photo looks like kamerakind one
Hi kamerakind, I have the same problem! Do you already found a solution? And my 6d shows me a message on the screen saying "Cannot playback image" and that image in the computer looks like yours. And when this occurs the camera freezes.
