Nice soccer shots, i really miss that since so long time ago, i think maybe my last was in 2013 or 2014.
And you have same cameras i have and almost same lenses too, i still consider my 300 2.8 as my favorite lens for soccer or some sports in general, and my 70-200 2.8II never disappoint as well, but i really wish if i sold my 1D 3 so long time ago and upgrade it to something else, now i can't sell neither 1D3 not 1DX to have any good value and then buy another two cameras for sports.
