i just got my 4008 ZM back from irv too. it took about 3 or so months. everything seemed in order till i set up my first test shot. nothing happened. i cant figure it out. i was hoping to pop off a few shots to start the near year off on a good foot, oh well. its going back to cali. i cant help but think its a user error since i just got it back, but i know my way around this camera fairly well. i like irv. i hope this mishap was a freak of nature and not something that happens often.
