We sometimes see this type of unexplained electronic equipment failure as we visit the U.K. crop circles with our tour group. The camera affected this time is a new Canon Rebel EOs T2i in the East Kennett formation. It lost it’s ability to focus as the person stepped into the formation, then it completely lost power for a few minutes. A few hours later it had completely recovered. (My camera video recorder also failed briefly as I attempted to record this anomalous event.)
