Yes, that is my point. I made the switch from my mrkIV on the promise of improved focus. The 5Dmrk3 is much faster to focus, but not seeing better results. The improvements in high ISO is noticeable, but for my application (wildlife and scenic) shooting in the dark is not really applicable. Sharpness and speed of focus is key for me. Could the 61 point focus system be so technically advanced that many users will have difficulty using it and achieving focus? Could it be that advanced? I have established that I'm a fool for selling my mrkIV, now what is a fool to do? Return the 5Dmrk3 and than purchase what? I'm asking myself if it is time to jump ship? Considering the issues with this focus system not sure that the 1DX will be any different, after all the 1DX has the same focus system. The only other advantage of the 1DX is the weather proof body and 14 fps. I don't shoot in the rain and unless your shooting hummingbirds I don't need 14fps either. I have one more test and calibration test to do today, then its decision time. It still bothers me that canon released a camera with focus issues and DPP software that is not up to the task. Canon has been quoted saying that the software fix will take 'some time'. REALLY? What where they using when they tested this camera?
