I unboxed my inspire 1 pro last night and after 4 hours of trying to get it to update DJI sent me to the chinese update page where they have an "isnpire 1 pro .bin" that finally worked. So I get that taken care of and turn the second remote on to test the movements and image. I turn the camera and notice a small buzzing when going across a certain spot. I go back and sit it on that spot and it vibrate viciously and makes a very loud buzzing (like metal on metal) Needless to say I am returning it to BH photo today for an exchange but was wondering if this is a bad sign?
Mine was growling at first too. I now think it had something to do with camera settings. It came pinned to the highest ISO setting and 'auto' de-selected. That's the 'auto' on ISO. I re-set this to 'auto' and the growling went away.
Now I'm focused on dealing with 'auto' exposure hunting for settings while recording video--snapping back and forth, almost a flicker. But that's another thread.
Oh, and on 'calibrate lens'. This is on the tools portion of the 'menu' in camera settings. It isn't clear whether the calibration is in progress, is it done, or is it frozen? Follow instructions and hit OK. Then the AF/MF goes to MF, the yellow auto-focus square goes white and a distance scale appears. But then that's all. I left it alone for a while but nothing changed. The white auto-focus square and AF/MF didn't go back to normal until re-booting the I1. Is this normal?
