Last Friday [25 August] in Ajman stadium, started at 4:45pm[16:45], as usual, i was using 1D3 and 1D2 with lenses 300 2.8IS and 70-200 2.8ISmk1.
In that game, my 1D3 wasn't focusing properly, say it wasn't focusing at all unless i do manual focus even it is on AF, i didn't know what's wrong, i went to C.Fn and tried to go back to what i was used to do, still, but i found it was in that C.Fn I, wow, a small setting make a big mistake, so i returned it to default or as it was before and my MKIII work again, i accepted it even it wasn't perfect tracking focus, but this problem is with many cameras, even my friends were complaining to same issue, so i decided i never look back about it and just keep shooting and whatever i can get i accept it and delete what is OOF.
