Hi, I have a brand new 7d Mark I I and took it out for the first time today and after half a dozen shots the AF stopped and the shutter wouldn't release, had to take battery out to get it going , sometimes it wouldn't even power down , had 1.0.4 firmware , anyone else had this problem , was shooting with a 70-200 f2.8 non IS , also tried the 24-105 f4 with the same issue. Reset camera settings tried different modes but just keeps happening. Frustrating
