Black Dot Issues?
It seems, the "Black Dot Scare" has gripped the EOS 5DMII community (with good cause). From what I can tell, not everyone is able to re-create the black dot effect. This leads me to believe it might be a limited run of cameras that have this problem. If you have noticed this issue with your camera, please post the last 4 digits of your serial number and we can try to figure this thing out.
