I have a kind of problem connected with continuous shooting mode speed in my 5d3.
When the battery level is over 50%, everything seems to be OK, so 6 fps.
But the problem starts, when it goes under 50%, so beginning from 49%. Then the shooting speed reduces to 3 fps without a reason.
I should add, that I'm working without battery grip, and the CF card is not the problem, because it's fast and, what is more, the shooting speed would probably reduce also over 50% of battery, if the problem is connected with memory card.
My 5d3 is not the only one that slows down under 50%, my friends 5d3 also behaves the same way. He bought the camera at the same time as I, in the same store, so our SNs are simillar. It's very annoying, especially when shooting sports, so we often change the battery for another one, when it goes under 50%...
Does anybody have the same problem with 5d3?
