Just got the Canon 5DMKIII and really love it. I have a 7D and this is quite a step up for me. Today, I had a few minutes so I rigged the 5D through an Atomos Connect system and into my Samurai recorder to test the camera and the Samurai together. They seemed to play nice, so that is a good thing. I edited in Final Cut X. It is certainly not be best work, but again this is only a test!
