I would send the camera and flash back too as they take rubbish photo's! Or maybe send the photographer back! JOKING!!
Back to the 1Dx... I had one ordered which arrived in my local Calumet store the other day and I told them I no longer wanted it. Not that I never had the beans to pay for it but I thought to myself 'Do I need it'? The 5D Mark III would easily give it a run for it's money (and even win in some cases, size, portability etc).
So, for now I'm happy with the 5D, I'll be waiting 'til they add more pixles to the X range before I buy.
