With all the long lens cameras covering the World Cup, I find it hard to believe there isn't even an incidental shot of the 7D Mk.II - that is if it's even there?
It is not hard to believe. With thousands of dollars on the line for that perfect shot I am sure the photographers are all aiming on the field. If it is there it either looks like a 1dx without the 1dx written on it or it looks like a 5d/ 7d without 5d/ 7d written on it so it would be hard to notice unless you are looking for it. Maybe once one of the photog's comes home and happens to look through the pictures that will not make them money there would be the possibility that they accidently got a good shot of a camera they do not recognize.
