My 5d mkii was sent in for repair twice for err 30. The second time I got the error was about a week after the first. I just had this happen again this morning. I'm supposed to shoot a band tomorrow and I'm an hour and a half away from a back up camera. My warranty expires on 12/16 and it's 12/12 today. WTF. When does the d700 replacement come out? The downside is Nikon only having 720p video recording in their cameras. I'm just starting to get into video and almost purchased a rig with follow focus for my camera last week. There should be some sort of lemon law for cameras.
