I am in the situation where i do a lot of interior low light images. I am not allowed to use flash. I have been using my 5d III but was wondering if the 1dx perform better in low light at higher iso? I do at times do continuous shooting and know that 1dx does 12 frames per second.
I have a Mark d5 III and the longest lens that I have is the 70 - 200mm 2.8. I am being asked to shoot indoor sports Basketball and hockey. I would like to get 300mm, but could only afford the 300mm 4, not sure if that will be fast enough and in mix low light conditions. Should I get the 300mm or get the 7d with the APC sensor which with the 70-200 2.8 give me the speed and 300+ distance?
