7D, 8FPS? only in good light!
Here is my guess:
I don't know about the 7d... but on my 5d2 the higher ISOs have a much higher MB per file.
A 100 iso RAW is around 20mb while a 12800 ISO file is around 40MB! That is double the data!!! As the ISO is boosted it makes for shorter bursts/slower shooting speeds as the cache is filled faster.
Though I ddont have a 7d to test with.. It it happening in the dark with low isos set?
otherwise I am guessing it is an intentional thing to allow for more time for the camera to lock.
