The filter size for the 60-600 is 105mm.
The 82mm for the 70-200 is a first but all the modern 16-35/24-70 lenses already have this size anyway, so it makes sense to have a common filter size - only 82mm instead of 77mm.

OK, the same as the previous sport..........that means front heavy again......

strange that the first sport is a larger lens with a larger front element yet suffered more vignetting and the F stop closed earlier zooming in than the G2...........

   Let's see what happens with this new one!
