Was shooting a tractor mowing grain today and noticed something I haven't seen before, It was an extremely clear day and I was shooting around noon. Shooting straight down on the green wheat I got a hot spot with the shadow of the Mavic Pro in the center. Thought it was a malfunction at first but realized it was a reflection of the sun off the field. Nothing similar when shooting at an angle to the ground. Didn't realize the sun would actually focus that way. Earlier or later in the day and it wouldn't have happened.
