Howevever, as I have tested the 6D for a day, I can say, that Moire is not a big issue for stills.
No, really, use search :-p
If I understand you correctly, you are saying, that the 6D suffers from Moire with stills a lot, too? Really? I only had it for one day, and didn't run into such problems, but it may depend heavily on the subject...
Oh my, you really want me to use search for you? http://www.canonrumors.com/forum/index.php?topic=18987.msg360151#msg360151
