Hello I recently got my 7D Mark II and love it however I am noticing some heavy focusing issues when I try to track my Kid. I am not sure what Case I was in, I typically do 1, 3, or 4. Al Servo Priority was set to Release and then focus for 2nd. Setting both to focus resulted in terrible results. Default middle might work best for me. I had this exact same issue on my 1D Mark IV with 70-200 IS II, It tracks cars or birds no problem but anything to do with my kid running around, It struggled really bad.
Do you think this is an issue with settings, lens or user error?
Below is a sequence of 18 images shot in RAW Converted to JPEG then uploaded to Imgur. Looking at the grass, There is plenty of focus room. I don't get it.
Settings were 1/800th - 1/1000th, f3.2 - f4, ISO 800 to 1250.
