Hey everyone, I'm very close to pulling the trigger on a 5D3, and probably will despite this question.

I'm keen to use the SD slot for an Eye-Fi card for transfer or jpgs for review on a tablet while shooting in the field. I've just noticed this article doing the rounds about the 5D's SD card slot...

So my question is, can anyone with the camera please give feedback on whether the SD card does slow the camera down noticeably when shooting continuous high speed? (SD card slot is 133x or 20MB/s) And further to that, the Eye-Fi is only Class 6 which is slower again (only 6MB/S), does anyone have any experience with it slowing down your camera?
