Guys, i need your advice. Recently I had bought Canon 1DX and I had found out that the 61 point auto focus speed (under single shot mode) is slightly slower (maybe 0.5 second) than my previous modal 7D. I had try several lenses in same light condition but I still found the same issue. For example normally when I half press the shuttle button, the 7D act extremely fast like no lag and focus indicator light up and beep immediately. When I half press the 1DX shuttle button, it seem needs half a second to process then its only light up the focus point and beep. AI servo and single point focus have no problem. I want to check with you guys, this is 1DX normal behavior or abnormal. Furthermore, it's something like I need to spend 1 to 2 second to snap a single shot in 7D and 2 to 3 second in 1DX. I had update the firm ware to 2.0.2 but the problem still exists. Thanks a lot.
