After considering the advice of folks on the forum -- thanks! -- I pulled the trigger on a 6D over the 5D3. Just made more sense based on my interests and seriousness. I have a few 45 MB/s cards, but wondering what the above is doing with RAW video, which I plan to explore in earnest. Thought there was a choke points in the recording speed -- of course, that could be irrespective of the available card speed..Anyway, maybe someone knows whether it's worth the hefty price tag. Thanks
