Cool, so it is fine to go high ISO for night soccer or some indoors with bad lights using 7D II, i will be using either 70-200 2.8 mkII or 300 2.8 mk1 which helps for quality.
Now from your last posts here i can confirm about buying 7D II and selling my 1D3, if i will shoot wildlife then i will use 1DX, mostly for birds or wildlife i don't shoot with 2 bodies even it may may the life easier, but in sports i mostly use 2 bodies, 1DX is as main, but i want to have my backup body as good as 1DX if not better but not another 1DX again, i hope i can have budget in the future so i can buy a newer camera that will be better than 1DX then i will keep 1DX as a backup.
Also, 7DII has 2 things that i want over 1D3, 1. Cropability, 2. MP [20mp vs. 10mp], so if i crop about 30-60% with 1D3 then with 7D2 i may crop at about 10-30% so i may not lose more of quality or details, and if i use 300mm then i may not crop more than 20% for most shots and 300 giving better results than the zoom so i keep 70-200 on 1DX for another better results with the zoom.
But, and BIG BUT is, i read a lot about the AF issue, don't know if it is with AI Servo because this is what i use always in shooting sports, so what is the major shooters experience with Ai Servo performance so far?
