This is a framegrab from video. I was a little hesitant that the 6d couldn't achieve that magic look like my 5D ii but it assurd me that the 6d is very capable.
Truthfully, I personally feel that the video thing has been overblown about the 6D. I have been very pleased with the video I have personally gotten from the 6D, and it is SO much better implemented than on the 5DII I used previously. I have seen great video from other people as well. Moire is an issue, but I have personally only seen it one time in my personal use.
